Invokes the remote WebService method based on the specified information
</summary>
<param name= "url" >webservice http form of address </param>
<param name= "namespace" > the namespace of the WebService to invoke </param>
<param name= "ClassName" > The class name of the WebService to invoke (excluding the namespace prefix) </param>
<param name= "methodname" > The WebService method name to invoke </param>

Execution results of <returns>webservice </returns>
<remarks>
If the call fails, the exception is thrown. Please call, properly intercept the exception.
Exception information can occur in two places:
1, the dynamic construction of WebService time, compileassembly failure.
2, webservice itself failed to execute.
</remarks>
<example>
<code>
Object obj = Invokewebservice ("Http://localhost/GSP_WorkflowWebservice/common.asmx", " Genersoft.Platform.Service.Workflow "," Common "," Gettooltype ", New object[]{" 1 "});
