Remarks

The HttpExpectationHeaderValue class is a token that represents a particular server behavior that is required by the client. The HttpExpectationHeaderValue is used in the Expect HTTP header on an HTTP request.

For example, 100-continue is a server behavior that the client might depend on and set using the HttpExpectationHeaderValue class.

The Expect property on the HttpRequestHeaderCollection returns an HttpExpectationHeaderValueCollection that contains HttpExpectationHeaderValue objects.
