The return format is

 & lt; S: Envelope XMLNS: s="http://schemas.xmlsoap.org/soap/envelope/" & gt; 
 
 True 
 OK 
 
 
 
 

Is the target to get the target value of

 & lt; S: Envelope XMLNS: s="http://schemas.xmlsoap.org/soap/envelope/" & gt; 
 
 True 
 OK 
 
 
 
 

This prefix how to set up, please?

Main point is how to add the ornament in front of the first?

Under the current code: use

 namespace WcfServiceLibrary 
{

Public delegate string DisplayContent (string content); 
//note: the use of "refactoring" menu "renamed" command, can change the code and the name of the class in the configuration file at the same time "Service1," 

[ServiceBehavior (InstanceContextMode=InstanceContextMode. Single Namespace="http://localhost/BOI/")] 
[XmlSerializerFormat] 
Public class WServiceInstance: IService_Contract 
{
Public DisplayContent AddContent; 

Public BoiResult Invoke (string form, string token, string funcName, string parameters) 
{
Var jsonres=AddContent (form + ";" + token + ";" + funcName + ";" + the parameters); 
Var data=https://bbs.csdn.net/topics/new BoiResult (); 
Data. InvokeResult=true; 
Data. The result=jsonres; 
return data; 
} 
} 

[DataContract (Namespace="")) 
[XmlSerializerFormat] 
Public class BoiResult 
{
[DataMember] 
Public bool InvokeResult; 

[DataMember] 
Public string result; 
} 
} 

 namespace WcfServiceLibrary 
{
//note: the use of "refactoring" menu "renamed" command, can change the code and configuration files at the same time the interface name "IService_Contract," 
[ServiceContract (Namespace="http://localhost/BOI/")] 
[XmlSerializerFormat] 
Public interface IService_Contract 
{
[OperationContract (Action="" Name=" Invoke ")] 
BoiResult Invoke (string form, string token, string funcName, string parameters). 
} 
}
