asp.net 抽象方法和虚方法的用法区别,用Global类重写Application_BeginRequest等方法为例子

不废话,直接贴代码

  public abstract class LogNetGlobal : System.Web.HttpApplication
{
protected void Application_Start()
{
Application_Start_();
}
//public static void RegisterRoutes(RouteCollection routes)
//{
// InitRoutes.SetStaticConfig(".html");
// InitRoutes ir = new InitRoutes(routes);
// ir.LoadRoutes(null);
//}
public void Application_BeginRequest(object sender, EventArgs e)
{
Application_BeginRequest_(sender, e);
LogNet.LogNetHttpContext.Items.AddBeginTime();
} public void Application_EndRequest(object sender, EventArgs e)
{
#region 将请求信息存入日志 string url = Request.Url.AbsoluteUri;
if (!url.ToLower().Contains("testpostjson.aspx") && !url.ToLower().Contains("readlog.aspx"))
{
LogNet.Log.WriteLog(Request);
}
#endregion
Application_EndRequest_(sender, e);
}
public void Application_Error(object sender, EventArgs e)
{
HttpApplication httpApp = sender as HttpApplication;
if (httpApp != null && httpApp.Context != null && httpApp.Context.Error != null)
{
LogNet.Log.WriteLog(httpApp.Context.Error);
}
Application_Error_(sender, e);
} /// <summary>
/// 抽象方法不能有方法体,子类必须要重写该方法
/// </summary>
protected abstract void Application_Start_();
/// <summary>
/// 虚方法一定要有方法体,子类可以选择重写该方法,可以通过base.Application_BeginRequest_(sender,e)的方式调用该基方法
/// </summary>
protected virtual void Application_BeginRequest_(object sender, EventArgs e) { }
protected virtual void Application_EndRequest_(object sender, EventArgs e) { }
protected virtual void Application_Error_(object sender, EventArgs e) { }
