Error Message Deciphered

Thankful the designer of vb.net have taken the view that error messages should be descriptive and helpful.
Some of the even suggest a solution.

Let's take this error message and decipher it.

No overload for 'GetAverage' takes 0 arguments


Let decode the error message.

• No Overload ...
  
  So what is an Overload?
  An overload is method that has the same name as another method in your class/module but with different input signatures.
  So I know know as something to do with one of the methods "GetAverage"

• takes 0 arguments
  
  So what is an argument?
  
  Arguments are the values you provide for a method's input parameters.
  

    Public Function Add(x As Integer, y As Integer) As Integer
      Return x + y
    End Function
    
    Dim z = Add(1,2)
    
  

  
  Parameters: x y
  
  Arguments: 1 2
  
  So it must be something to the number of parameters I'm passing, or not passing.

Message Deciphered
No Overload of the Method "GetAverage" has Zero number of Parameters, to take the Zero number of parameters I'm passing.
So that suggest I'm not providing enough arguments.


Conclusions

Don't understand the full error message, then break it up it chunks.
Research and understand each aspect and concepts.

That the debugging and analysis skills learn for programming, apply not only to programming! Use them.
