getDate.wsdl (4.04 KB)

How is your getDate message defined in the imported schema? It appears that C# .Net is having trouble deserializeing (unmarshalling)the soap message into C# objects.


Hi, Mark

Thanks for your response. but i can’t understander what you say. would you please like to give me more detailed information?


Your WSDL file imports the schema “” which defines the getDate message. Your C# client uses this schema to build a class (or classes) that define the getDate message. The classes must know how to read the getDate message and it appears they don’t know “understand” the getDate object defined in your schema. The terms “deserialize” and “unmarshal” are the technical terms to describe the process that your C# classes uses to “read/understand” the getDate message.

HTH explain Marks’ comment.
