WebRequest.Create Method (Uri)

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.

For example, when a URI beginning with http:// or https:// is passed in requestUri, an HttpWebRequest is returned by Create. If a URI beginning with ftp:// is passed instead, the Create method will return a FileWebRequest instance. If a URI beginning with file:// is passed instead, the Create method will return a FileWebRequest instance.

The pre-registered reserve types already registered include the following:

• http://

• https://

• ftp://

• file://

The .NET Framework includes support for the http://, https://, ftp://, 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();
