WebRequest.Create Method (Uri)

Initializes a new WebRequest instance for the specified URI scheme.

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

public static WebRequest Create (
	Uri requestUri
)
public static WebRequest Create (
	Uri requestUri
)
public static function Create (
	requestUri : Uri
) : WebRequest

Parameters

requestUri

A Uri containing the URI of the requested resource.

Return Value

A WebRequest descendant for the specified URI scheme.
Exception typeCondition

NotSupportedException

The request scheme specified in requestUri is not registered.

ArgumentNullException

requestUri is a null reference (Nothing in Visual Basic).

SecurityException

The caller does not have permission to connect to the requested URI or a URI that the request is redirected to.

The Create method returns a descendant of the WebRequest class determined at run time as the closest registered match for requestUri.

For example, if you create a WebRequest descendant, Handler1, to handle requests to http://www.contoso.com/text/ and another named Handler2 to handle requests to http://www.contoso.com/code/, you can use Create method to return the WebRequest descendant associated with either specified URI.

To return a descendant of the WebRequest class based on only the scheme portion of a URI, use the CreateDefault method.

The .NET Framework includes support for the http://, https://, and file:// URI schemes. Custom WebRequest descendants to handle other requests are registered with the RegisterPrefix method.

The following example uses Create to instantiate an HttpWebRequest instance. A Uri representing the target URL is used as the constructor parameter.

// Create a new 'Uri' object with the specified string.
Uri myUri =new Uri("http://www.contoso.com");
// Create a new request to the above mentioned URL.    
WebRequest myWebRequest= WebRequest.Create(myUri);
// Assign the response object of 'WebRequest' to a 'WebResponse' variable.
WebResponse myWebResponse= myWebRequest.GetResponse();

// Create a new 'Uri' object with the specified string.
Uri myUri = new Uri("http://www.contoso.com");
// Create a new request to the above mentioned URL.    
WebRequest myWebRequest = WebRequest.Create(myUri);
// Assign the response object of 'WebRequest' to a 'WebResponse' 
// variable.
WebResponse myWebResponse = myWebRequest.GetResponse();
