Using c# to develop telecom short message service, based on ISAG, they provided some WSDL files, but I don't know how to use them. Friends who developed SP left QQ, thank you.

Does he provide a web service interface? Start menu, program menu, Visual Studio menu, Visual Studio tools and Visual Studio command prompt. After opening, you can use the WSDL command to generate the local calling class of the interface.

Then right-click in the project, add an existing item, then select the CS file generated by WSDL, and then directly create the class object of the file, and then you can operate directly through the created object, just like using the local class method.
