如何调用非静态webmethod表单客户端静态方法？

Question

I' m trying to do something but I'm not sure if it is allowed in c# here is what I'm tring:

I have a Web Method which is not a static here it is:

   [WebMethod]
    public Byte[] recStuff(Byte[] recstuffile)
    {
        myfile = Unzip(muStuff);

        return null;
    }

and here is my client:

 public static  XmlDataService.StufServiceSoapClient lhaservice = null;
        public static void Autoupload()
        {
            string fileContents = File.ReadAllText(XMLStuffName);
            string text = fileContents;
            byte r2 = Zip(text);
            lhaservice.recStuff(r2);
        }

I am getting Error that:

Object reference not set to an instance of an object.

what can I do here?

Answer 1

It is very logical. lhaservice = null. Initialize it.

Answer 2

In any case you have to instantiate lhaservice first before you use it in your (static) constructor:

lhaservice = new XmlDataService.StufServiceSoapClient();

...but unless you show all your relevant code we don't really know for sure what the problem could be in your code.

Note: avoid static classes and operations if they don't make any sense. Make them non-static and create an instance before using the Autoupload operation. Your code will become more flexible and testable. So you might want to rethink your code.
