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


[PermissionSetAttribute(SecurityAction.LinkDemand, Name = "FullTrust")]
public sealed class PatternMatcher


Creates a PatternMatcher instance based on the input type.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Searches a text input to deserialize an object representing a Web method return value.


Returns a string that represents the current object.(Inherited from Object.)

The PatternMatcher class performs pattern matching using regular expressions to find Web method return values in text encoded in the body of an HTTP response. The PatternMatcher class is called by the client-side TextReturnReader class, which deserializes Web service return values.

Text pattern matching provides a way for Web services to retrieve HTML content without converting it to XML documents that must be bound to XML Schema definitions. Regular expression search targets are specified in a Web Services Description Language (WSDL) document via match XML elements within text elements. Both elements belong to the namespace

When match elements are specified in a WSDL document, the Wsdl.exe tool applies MatchAttribute attributes to the corresponding Web methods in the client proxy class that is generated. A MatchAttribute attribute's properties establish the search criteria for a PatternMatcher instance.

A developer typically does not need to directly use PatternMatcher.
