asp.net中有關URL的信息

 【說明】如果你已經熟悉了，請不必往下看，如果你還不熟悉，請做下參考，因爲經常在asp.net中需要獲取有關URL相關方面的信息，雖然msdn上列出了各種方法，無奈方法和屬性太多，沒辦法一一記住，就做了個例子，將與路徑和文件信息相關的參數通過一個方法列出來，以備平時查閱。

    {
        Response.Write("Request.AppRelativeCurrentExecutionFilePath=" + Request.AppRelativeCurrentExecutionFilePath + "<br>");
        Response.Write("Request.CurrentExecutionFilePath=" + Request.CurrentExecutionFilePath + "<br>");

        Response.Write("uri.Port=" + uri.Port + "<br>");
        Response.Write("uri.Segments=");
        foreach (string str in uri.Segments)
        {
            Response.Write( str+ ",");
        }
    }
}
