Asp.net中获取应用程序完整Url路径的小例子

代码如下:

/// <summary> 
/// Gets the absolute root 
/// </summary> 
public static Uri AbsoluteWebRoot 
{ 
    get  www.zzvips.com
    { 
        var context = HttpContext.Current; 
        UriBuilder uri = new UriBuilder(); 
        uri.Host = context.Request.Url.Host; 
        if (!context.Request.Url.IsDefaultPort) 
        { 
            uri.Port = context.Request.Url.Port; 
        } 

        uri.Path = VirtualPathUtility.ToAbsolute("~/"); 

        Uri absoluteWebRoot = uri.Uri; 

        return absoluteWebRoot; 
    } 
}
