網站配置一般用來保存網站的一些設置,寫在配置文件中比寫在數據庫中要合適一下,因為配置文件本身帶有緩存,隨網站啟動讀入緩存中,速度更快,而保存在數據庫中要單獨為一條記錄創建一個表,結構不夠清晰,而且讀寫也沒有配置文件容易實現。這次要做的是網站的基本信息,數據保存在SiteConfig.config。
在14年的時候寫過一篇博客《.Net MVC 網站中配置文件的讀寫》 ,在那篇博客中把思路和方法都已經寫清楚了,這次的實現思路和上次一樣,只是那次自己實現了KeyValueElement類和KeyValueElementCollection類,其實這兩個類在System.Configuration命名空間中都已經實現,直接使用就行。
一、網站配置類(SiteConfig)
1、在Nninesky.Core項目新建文件夾Config
2、在Config文件夾添加類SiteConfig。

using System.ComponentModel.DataAnnotations; using System.Configuration; namespace Ninesky.Core.Config { /// <summary> /// 網站配置類 /// </summary> public class SiteConfig : ConfigurationSection { private static ConfigurationProperty _property = new ConfigurationProperty( string .Empty, typeof (KeyValueConfigurationCollection), null , ConfigurationPropertyOptions.IsDefaultCollection); [ConfigurationProperty( "" , Options = ConfigurationPropertyOptions.IsDefaultCollection)] private KeyValueConfigurationCollection keyValues { get { return (KeyValueConfigurationCollection) base [_property]; } set { base [_property] = value; } } /// <summary> ///網站名稱 /// </summary> [Required(ErrorMessage = "*" )] [StringLength(50, ErrorMessage = "最多{1}個字符" )] [Display(Name = "網站名稱" )] public string SiteName { get { return keyValues[ "SiteName" ] == null ? string .Empty: keyValues[ "SiteName" ].Value; } set { keyValues[ "SiteName" ].Value = value; } } /// <summary> ///網站標題 /// </summary> [Required(ErrorMessage = "*" )] [StringLength(50, ErrorMessage = "最多{1}個字符" )] [Display(Name = "網站標題" )] public string SiteTitle { get { return keyValues[ "SiteTitle" ] == null ? string .Empty: keyValues[ "SiteTitle" ].Value; } set { keyValues[ "SiteTitle" ].Value = value; } } /// <summary> ///網站地址 /// </summary> [DataType(DataType.Url)] [Required(ErrorMessage = "*" )] [StringLength(500, ErrorMessage = "最多{1}個字符" )] [Display(Name = "網站地址" )] public string SiteUrl { get { return keyValues[ "SiteUrl" ] == null ? "http://" : keyValues[ "SiteUrl" ].Value; } set { keyValues[ "SiteUrl" ].Value = value; } } /// <summary> ///Meta關鍵詞 /// </summary> [DataType(DataType.MultilineText)] [StringLength(500, ErrorMessage = "最多{1}個字符" )] [Display(Name = "Meta關鍵詞" )] public string MetaKeywords { get { return keyValues[ "MetaKeywords" ] == null ? string .Empty: keyValues[ "MetaKeywords" ].Value; } set { keyValues[ "MetaKeywords" ].Value = value; } } /// <summary> ///Meta描述 /// </summary> [DataType(DataType.MultilineText)] [StringLength(1000, ErrorMessage = "最多{1}個字符" )] [Display(Name = "Meta描述" )] public string MetaDescription { get { return keyValues[ "MetaDescription" ] == null ? string .Empty : keyValues[ "MetaDescription" ].Value; } set { keyValues[ "MetaDescription" ].Value = value; } } /// <summary> ///版權信息 /// </summary> [DataType(DataType.MultilineText)] [StringLength(1000, ErrorMessage = "最多{1}個字符" )] [Display(Name = "版權信息" )] public string Copyright { get { return keyValues[ "Copyright" ] == null ? "Ninesky 版權所有" : keyValues[ "Copyright" ].Value; } set { keyValues[ "Copyright" ].Value = value; } } } } |
Siteconfig類繼承自ConfigurationSection,繼承自這個類是才能讀寫配置節。
在類中聲明一個配置元素的子元素 private static ConfigurationProperty _property,子元素的配置實體類型是KeyValueConfigurationCollection(鍵/值集合)。
然后徐再在類中聲明一個屬性private KeyValueConfigurationCollection keyValues。利用keyValues獲取、設置配置節鍵/值集合。

[ConfigurationProperty( "" , Options = ConfigurationPropertyOptions.IsDefaultCollection)] private KeyValueConfigurationCollection keyValues { get { return (KeyValueConfigurationCollection) base [_property]; } set { base [_property] = value; } } |
然后就可以使用keyValues[“name”]獲取設置具體配置了。

/// <summary> ///網站名稱 /// </summary> [Required(ErrorMessage = "*" )] [StringLength(50, ErrorMessage = "最多{1}個字符" )] [Display(Name = "網站名稱" )] public string SiteName { get { return keyValues[ "SiteName" ] == null ? string .Empty: keyValues[ "SiteName" ].Value; } set { keyValues[ "SiteName" ].Value = value; } } |
看起來是不是跟其他模型類差不多,知識Get;Set;有所不同。
二、設置配置文件的類型和路徑
打開Nniesky.web項目的 web.config文件,找到configSections,然后添加SiteConfig配置節
紅框部分為添加類型,說明了配置節的名稱和類型,注意紅線部分,restartOnExternalChanges設為"false",如果不設置,配置文件修改后會重啟網站。
在配置文件的結尾</configuration>添加配置文件的路徑
圖中紅框部分為添加內容,指明SiteConfig的位置文件在網站目錄Config文件夾下名為SiteConfig.config的文件。
然后在項目中添加Config文件夾,然后添加名為SiteConfig.config的配置文件。

<? xml version = "1.0" encoding = "utf-8" ?> < SiteConfig > < add key = "SiteName" value = "Ninesky" /> < add key = "SiteTitle" value = "1133" /> < add key = "SiteUrl" value = "http://mzwhj.cnblogs.com" /> < add key = "MetaKeywords" value = "關鍵詞," /> < add key = "MetaDescription" value = "描述" /> < add key = "Copyright" value="Ninesky 版權所有<a>11</ a >" /> </ SiteConfig > |
配置文件中的鍵名與SiteConfig的屬性名對應。
三、控制器和視圖
1、配置文件的讀取
在Ninesky.Web/Areas/Control/Controllers【右鍵】->添加->控制器,輸入控制器名ConfigController。
在控制其中添加方法SiteConfig方法

代碼很簡單,利用WebConfigurationManager的GetSection方法就將配置信息讀出來了。
右鍵添加視圖,將個屬性顯示出來。

@model Ninesky.Core.Config.SiteConfig @{ ViewBag.Title = "站點設置" ; } @section SideNav{@Html.Partial( "SideNavPartialView" )} <ol class = "breadcrumb" > <li><span class = "glyphicon glyphicon-home" ></span> @Html.ActionLink( "首頁" , "Index" , "Home" )</li> <li>@Html.ActionLink( "系統設置" , "Index" )</li> <li class = "active" >站點設置</li> </ol> @ using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class = "form-horizontal" > @Html.ValidationSummary( true , "" , new { @ class = "text-danger" }) <div class = "form-group" > @Html.LabelFor(model => model.SiteName, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.SiteName, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.SiteName, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.SiteTitle, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.SiteTitle, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.SiteTitle, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.SiteUrl, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.SiteUrl, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.SiteUrl, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.MetaKeywords, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.MetaKeywords, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.MetaKeywords, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.MetaDescription, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.MetaDescription, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.MetaDescription, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > @Html.LabelFor(model => model.Copyright, htmlAttributes: new { @ class = "control-label col-md-2" }) <div class = "col-md-10" > @Html.EditorFor(model => model.Copyright, new { htmlAttributes = new { @ class = "form-control" } }) @Html.ValidationMessageFor(model => model.Copyright, "" , new { @ class = "text-danger" }) </div> </div> <div class = "form-group" > <div class = "col-md-offset-2 col-md-10" > <input type= "submit" value= "保存" class = "btn btn-default" /> </div> </div> </div> } |
2、配置文件的保存。
在控制器中再添加一個[HttpPost]類型的SiteConfig方法。
- [ValidateInput(false)]
- [ValidateAntiForgeryToken]
- [HttpPost]
- public ActionResult SiteConfig(FormCollection form)
- {
- SiteConfig _siteConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~").GetSection("SiteConfig") as Ninesky.Core.Config.SiteConfig;
- if (TryUpdateModel<SiteConfig>(_siteConfig))
- {
- _siteConfig.CurrentConfiguration.Save();
- return View("Prompt", new Prompt() { Title = "修改成功", Message = "成功修改了網站設置", Buttons = new List<string> { "<a href='"+Url.Action("SiteConfig") +"' class='btn btn-default'>返回</a>" } });
- }
- else return View(_siteConfig);
- }
- }
代碼也非常簡單,與讀取配置文件相同,使用WebConfigurationManager的GetSection方法將配置信息讀入_siteConfig中,然后用TryUpdateModel<SiteConfig>(_siteConfig)綁定視圖提交過來的信息。
如果綁定成功,利用_siteConfig.CurrentConfiguration.Save()方法保存配置信息(這個方法繼承自ConfigurationSection,不用自己實現)。
效果如下圖
