A field initializer cannot reference the nonstatic field method or property

Question

public readonly int items = 3;
private System.Windows.Forms.TextBox[,] statsBonus = new System.Windows.Forms.TextBox[6, items];

It's giving me this error on the "items" variable. How do I make it so that I can use a variable called "items" instead of having to write 3 in every field that uses the number 3?

If I want to edit this on the code, I don't want to have to change the number 3 to something else manually. I want to use a variable so all I have to do is just change the variable to change everything.

public readonly int items = 3; is working on my computer. What version of .Net do you use ? — cubitouch, Jan 06 '14 at 22:06
@cubitouch How do I find which version I'm using .NET? I'm on Visual Studio 2012 — puretppc, Jan 06 '14 at 22:08
@puretppc Right click project -> Properties -> Application tab — Pierre-Luc Pineault, Jan 06 '14 at 22:10
@puretppc I'm reproducing your example into a console application with .Net 4.0. See you project properties for more informations. — cubitouch, Jan 06 '14 at 22:10
Interesting... Someone can tell why my console app' is running fine ? — cubitouch, Jan 06 '14 at 22:16

Instead of using readonly use const

It's running properly. But what's the difference between those 2 types? – puretppc Jan 06 '14 at 22:06
@puretppc, *readonly* field value can be set in *constructor* and also field initializer, but *const* file value can only be set via field initializer. – Arin Ghazarian Jan 06 '14 at 22:10

You must use

const int items = 3;

Readonly variables can be only assigned via constructer – Omer Jan 06 '14 at 22:08

One option

Move it to the constructor:

public ClassName()
{
  statsBonus = new System.Windows.Forms.TextBox[6, items];
}

Better option

Make items a const.
