Can't call private C#?

Question

WPF

public void test1()
        {
            int a =25;
int b =25;
int c=a+b   
        }
        private void button_Click(object sender, RoutedEventArgs e)
        {
            test1();
        }

Mistake.
It turns
out that the called object was rejected.

Answer 1

I could be wrong, but " button_click " shouldn't be public ?

Answer 2

First, provide the text of the error so that we can help you.
And secondly, the test1() method lacks a semicolon in the third line.
