On which port my web application is running asp.net C#

Question

有没有办法找到我的Web应用程序使用C＃代码运行的端口，因为我喜欢用整数变量写它？

Answer 1

You can get it this way, MSDN , If you could not see port in url it means the port is 80.

int port =  Request.Url.Port;

or you can get from url

Uri uri = new Uri("http://www.mywebsite.com:80/pages/page1.aspx");
int port  = uri.Port;

Answer 2

If you running from Visual Studio then every time it will pick up a new port number, once you have deployed your application then it will pick up the port given for your website.

The default port is 80 .

Answer 3

如果使用Visual Studio Development Server或在IIS设置中选择端口，则可以在项目设置中选择端口。
