static function generates error CS0119:

Questions & Answers

I have the following code:

public class Button{ 
   static int Widest;
   static int Height;
   .
   .
   .
   static public void Calc(int c,int w,int ih,int th,int m,int sw,int sh){
      .
      .
      .
   }

}
. 
.
.
Button b1 = new Button(tCancel ,can,st);
Button b2 = new Button(tRestart,res,st);
Button b3 = new Button(tExit   ,exi,st);
Button.Calc(3,b1.Wider(b2.Wider(b3)),Font2,Font0,MarginY,Width,Height);   // this line generates an error!

This code generates the following error:

error CS0119: Expression denotes a method group', where a variable’, value' or type’ was expected

However I don’t understand why… If I make Calc non staic like this:

public void Calc(int c,int w,int ih,int th,int m,int sw,int sh){
      .
      .
      .
   }

and I call it like this:

b1.Calc(3,b1.Wider(b2.Wider(b3)),Font2,Font0,MarginY,Width,Height); // this compiles OK!

then no error is reported.

Since Calc only affects static varibles inside Button, the logical thing is to make it static, however if I declare it static it simply won’t compile… I have lots of static funtions declared, and lots of static function calls either, but this is the only one that gives me trouble… And I can’t figure out why.

For static function declare as:

 public static void muFunc(int a) {
  ...
 }

Than, change to:

 public static void Calc(int c,int w,int ih,int th,int m,int sw,int sh) {
  ...
 }

I hope that it will help you.
