检索域名网址

我想在asp.net中检索我的域名网址.

例如,如果我的网址是:

http://www.mydomain.com/blog/currentPage.aspx?id=156

我只想要这个部分

http://www.mydomain.com/blog/

谁能帮我吗？

你有很多选择:

string root = this.ResolveUrl("~")

要么

Uri requestUri = Context.Request.Url;
string baseUrl = requestUri.Scheme + Uri.SchemeDelimiter + requestUri.Host + (requestUri.IsDefaultPort ? "" : ":" + requestUri.Port);

要么

string baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);

如果你想将/ blog附加到最后两个,请添加

+ Request.ApplicationPath

// Request.Uri
Uri originalUrl = new Uri("https://www.example.com/blog/currentPage.aspx?id=156");

// www.examle.com
string domain = originalUrl.Host;

// https://www.example.com
string domainUrl = String.Concat(originalUrl.Scheme, Uri.SchemeDelimiter, originalUrl.Host);
