在.net2.0中新增类HttpRuntimeSection :
static public double getMaxlength()
{
System.Web.Configuration.HttpRuntimeSection hrs = new System.Web.Configuration.HttpRuntimeSection();
////return hrs.MaxRequestLength * 1024;
return hrs.MaxRequestLength ;
}
{
System.Web.Configuration.HttpRuntimeSection hrs = new System.Web.Configuration.HttpRuntimeSection();
////return hrs.MaxRequestLength * 1024;
return hrs.MaxRequestLength ;
}
但上述方法读到的值却始终是4096,查阅MSDN,得知System.Web.Configuration(.net2.0中新增的类)的属性和方法除了AppSettings之外均只能读取"不可自定义的属性和功能",没有更好的办法,只好折衷:用.net1.1的方法解决:
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();
*/
}
{
//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();
*/
}
不知有没有更好的办法??
