Uri.Port Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the port number of this URI.

Namespace: System
Assembly: System (in System.dll)

Syntax

'Declaration
Public ReadOnly Property Port As Integer

public int Port { get; }

Property Value

Type: System.Int32
An Int32 value that contains the port number for this URI.

Exceptions

Exception	Condition
InvalidOperationException	This property is valid only for an absolute Uri instance.

Remarks

The port number defines the protocol port used for contacting the server referenced in the URI. If a port is not specified as part of the URI, the Port property returns the default value for the protocol. If there is no default port number, this property returns -1.

Examples

The following example writes the URI port number to the console. In this case, the value is the default port number for HTTP, port 80.

  Dim baseUri As New Uri("https://www.contoso.com/")
  Dim myUri As New Uri(baseUri, "catalog/shownew.htm?date=today")

  outputBlock.Text &= "Uri.Port: "
  outputBlock.Text &= myUri.Port
  outputBlock.Text &= vbCrLf

      Uri baseUri = new Uri("https://www.contoso.com/");
      Uri myUri = new Uri(baseUri,"catalog/shownew.htm?date=today");

      outputBlock.Text += "Uri.Port: ";
      outputBlock.Text += myUri.Port;
      outputBlock.Text += "\n";
