I agree with @aspnet_regiis.

The same type of question is discussed here[^].

The WebMethods are always atatic.
For details check the link below.

Why do ASP.NET AJAX page methods have to be static?[^]

So, why do page method calls have to be static?

If you’re implementing page methods, you’re probably well aware of their excellent performance. They are especially performant compared to the UpdatePanel’s partial postbacks.

They are efficient largely because they do not require the ViewState to be POSTed and they do not create an instance of the Page, while partial postbacks do both of these things. As we now know, a page method couldn’t create an instance of the page even if desired, since the ViewState isn’t provided in the request.

This is exactly why they must be marked as static. They cannot interact with the instance properties and methods of your Page class, because a page method call creates no instance of the Page or any of its controls.

Page methods are roughly equivalent to shorthand for standalone web services. In fact, the ScriptManager even calls them exactly as it would a regular web service.

Go through the link and learn the fundamentals.

As the WebMethod is static, it cannot call one normal method of the Page class.
If you want to call one method inside the WebMethod, you need to mark it as Static.

Thanks...

Solution 1

You declare the private method what you wants to call as static

C#

[WebMethod]
public static string MyWebMethod(string postCode)
{
// My webmethod code
string str = MyPrivateMethod(2,5);
}

private static string MyPrivateMethod(int a, int b)
{
// My private method code
}

Sorry, If I have missed some other obvious question.

Thanks to Tadit Dash for pointing out the issues.

The second function "MyPrivateMethod" has to be static.

Would you please explain why ?

Sorry. I have also missed one thing in my previous comment.
That is - the webmethod also need to be static, which you have done wrong here.
And
as webmethods are always static, so, it cannot call one normal function.
It can only call one static function.

If you still have doubts, please try with the codes you have written and let me know, it works or not.

Thanks...

yes, You are right. At first, I overlooked as simple web service. After your comment realized its a webmethod in aspx page.
Updated solution to declare both method as static. Thanks Tadit Dash

Most welcome, my pleasure.
Thanks Milind...

I think you also need to change the first line in your answer
"I fail to understand the purpose behind the question. You call any other method from WebMethod, just like you call any other function from any function.".

It would be better you change it a little bit...

Thanks Millind...
