UriBuilder Constructor (String, String, Int32)

Initializes a new instance of the UriBuilder class with the specified scheme, host, and port.

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

public UriBuilder(
	string scheme,
	string host,
	int portNumber


Type: System.String
An Internet access protocol.
Type: System.String
A DNS-style domain name or IP address.
Type: System.Int32
An IP port number for the service.


portNumber is less than -1 or greater than 65,535.

The UriBuilder instance is initialized with the Scheme property set to schemeName, the Host property set to hostName, and the Port property set to portNumber. The Path property is set to the slash character (/).

If the portNumber is set to a value of -1, this indicates that the default port value for the scheme will be used to connect to the host.

The following example creates a UriBuilder instance that contains the URI

UriBuilder myUri = new UriBuilder("http","",8080);
