WebRequest.CreateHttp Method (String)

Initializes a new HttpWebRequest instance for the specified URI string.

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

public static HttpWebRequest CreateHttp(
	string requestUriString
)

Parameters

requestUriString
Type: System.String
A URI string that identifies the Internet resource.

Return Value

Type: System.Net.HttpWebRequest
An HttpWebRequest instance for the specific URI string.

ExceptionCondition
NotSupportedException

The request scheme specified in requestUriString is the http or https scheme.

ArgumentNullException

requestUriString is null.

SecurityException

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

UriFormatException

The URI specified in requestUriString is not a valid URI.

The CreateHttp(String) method returns an instance of the HttpWebRequest class for the requestUriString.

When a URI that begins with http:// or http:// is passed in the requestUriString parameter, a HttpWebRequest is returned by CreateHttp(String). Another other scheme will throw an NotSupportedException.

The CreateHttp(String) method uses the requestUriString parameter to create a Uri instance that it passes to the new HttpWebRequest. If the method is successful, the AllowReadStreamBuffering property on the returned HttpWebRequest instance is set to false.

The .NET Framework includes support for the http:// and https:// URI schemes. Custom WebRequest descendants to handle other requests are registered with the RegisterPrefix method. The Create(String) method can be used to create a descendant of the WebRequest class for other schemes.
