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

public UriBuilder (
	string scheme,
	string host,
	int port,
	string path,
	string extraValue
public UriBuilder (
	String scheme, 
	String host, 
	int port, 
	String path, 
	String extraValue
public function UriBuilder (
	scheme : String, 
	host : String, 
	port : int, 
	path : String, 
	extraValue : String



An Internet access protocol.


A DNS-style domain name or IP address.


An IP port number for the service.


The path to the Internet resource.


A query string or fragment identifier.

Exception typeCondition


extraValue is neither a 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 (?).


port is less than 0.

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#top.

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

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