MimeFormatter Class

Provides an abstract base class for all readers and writers for Web services and clients implemented using HTTP but without SOAP.

Namespace: System.Web.Services.Protocols
Assembly: System.Web.Services (in system.web.services.dll)

Web service writers and readers serialize and deserialize, respectively, between the parameter or return objects of Web methods and the HTTP request or response streams. The MimeFormatter class establishes a common interface and functionality for reader and writer classes, in both client and service-side .

The MimeFormatter class supports the .NET Framework's implementations of Web services via the HTTP-GET and HTTP-POST operations. In HTTP-GET operations request parameters are encoded in the HTTP request's Uniform Resource Locator (URL). In HTTP-POST operations, request parameters are encoded in the HTTP request body, as with an HTML form. With both implementations, the return value appears in the HTTP response body as a non-SOAP XML document.

A developer typically does not need to directly use MimeFormatter or its descendant classes. Instead, when the Wsdl.exe tool generates client proxy code according to the HTTP-GET or HTTP-POST implementations, it applies the HttpMethodAttribute to each Web method and sets the attribute's ParameterFormatter and ReturnFormatter properties to the appropriate type derived from the MimeFormatter class. On the server, the appropriate derived types are used according to settings in an ASP.NET configuration file (Web.config). On the client the appropriate derived types are determined from the WSDL.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
