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

public class HttpVersion

The HttpVersion type exposes the following members.

Public methodHttpVersionInitializes a new instance of the HttpVersion class.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public fieldStatic memberVersion10Defines a Version instance for HTTP 1.0.
Public fieldStatic memberVersion11Defines a Version instance for HTTP 1.1.

The HttpVersion class defines the HTTP versions that are supported by the HttpWebRequest and HttpWebResponse classes. The HTTP version number is used to control version-specific features of HTTP, such as pipelining and chunking.

The following example demonstrates the use of HttpVersion.

			// Create a 'HttpWebRequest' object.
			HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create("");
			Console.WriteLine("\nThe 'ProtocolVersion' of the protocol before assignment is :{0}",myHttpWebRequest.ProtocolVersion);
			// Assign Version10 to ProtocolVersion.
			// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
			HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
			Console.WriteLine("\nThe 'ProtocolVersion' of the protocol after  assignment is :{0}",myHttpWebRequest.ProtocolVersion);
			Console.WriteLine("\nThe 'ProtocolVersion' of the response object is :{0}",myHttpWebResponse.ProtocolVersion);
