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

Initializes a new instance of the UriBuilder class with the specified scheme, host, port number, path and query string or fragment identifier.

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


Public Sub New ( _
    scheme As String, _
    host As String, _
    port As Integer, _
    path As String, _
    extraValue As String _
public UriBuilder(
    string scheme,
    string host,
    int port,
    string path,
    string extraValue


  • host
    Type: System.String
    A DNS-style domain name or IP address.
  • port
    Type: System.Int32
    An IP port number for the service.
  • extraValue
    Type: System.String
    A query string or fragment identifier.


Exception Condition

extraValue is neither nulla null reference (Nothing in Visual Basic) nor Empty, nor does a valid fragment identifier begin with a number sign (#), nor a valid query string begin with a question mark (?)


scheme is not a valid scheme name.


port is less than 0 or greater than 65,535.


The UriBuilder instance is initialized with the Scheme property set to schemeName, the Host property set to hostName, the Port property set to portNumber, and the Path property is set to pathValue. If extraValue begins with a number sign (#), then Fragment is set to extraValue. If extraValue begins with a question mark (?), then Query is set to extraValue.


The following example creates a UriBuilder instance that contains the URI http://www.contoso.com:8080/index.htm\#to.

  Dim myUri As New UriBuilder("http", "www.contoso.com", 8080, "index.htm", "#top")

      UriBuilder myUri = new UriBuilder("http","www.contoso.com",8080,"index.htm","#top");
