如何读取MaxRequestLength的值----（.net2.0)

static public double getMaxlength()

{

System.Web.Configuration.HttpRuntimeSection hrs = new System.Web.Configuration.HttpRuntimeSection();

////return hrs.MaxRequestLength * 1024;

return hrs.MaxRequestLength ;

}

static public string getMaxlengthByAppSetting()

{

//先在Web.Config文件中增加一个key ****************************************//

// <appSettings>

// <add key="maxRequestLength" value="1550000"/>

//</appSettings>

//再来读取这个值，遗憾的是，这样只能写两遍，即

//<system.web>

//<httpRuntime maxRequestLength="1550000" executionTimeout="3600"/>

//</system.web>

//这两个值必须保持一致。

Configuration config = WebConfigurationManager.OpenWebConfiguration("~");

return config.AppSettings.Settings["maxRequestLength"].Value;

　/* *********************以下为修改某个AppSettings的Key值。

////Configuration config = WebConfigurationManager.OpenWebConfiguration("~");

////if (config.AppSettings.Settings["MyAppKey"] == null)

//// config.AppSettings.Settings.Add("MyAppKey", "Hello!");

////else

//// config.AppSettings.Settings["MyAppKey"].Value = "Hello2!";

////config.Save();

}
