我的方法:

new UriBuilder(url) { Query = string.Empty }.ToString()

or

new UriBuilder(url) { Query = string.Empty }.Uri

Request.RawUrl.Split(new[] {'?'})[0];

    string url = "http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye";
    string path = url.split('?')[0];

我已经创建了一个简单的扩展，因为其他一些答案抛出空异常，如果没有QueryString开始:

public static string TrimQueryString(this string source)
{ 
    if (string.IsNullOrEmpty(source))
            return source;

    var hasQueryString = source.IndexOf('?') != -1;

    if (!hasQueryString)
        return source;

    var result = source.Substring(0, source.IndexOf('?'));

    return result;
}

用法:

var url = Request.Url?.AbsoluteUri.TrimQueryString() 

var canonicallink = Request.Url.Scheme + "://" + Request.Url.Authority + Request.Url.AbsolutePath.ToString();

System.Uri。GetComponents，只是指定你想要的组件。

Uri uri = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
uri.GetComponents(UriComponents.SchemeAndServer | UriComponents.Path, UriFormat.UriEscaped);

输出:

http://www.example.com/mypage.aspx
