[C#] Global Variables.

Hello, I have 2 windows forms in my C# application. I want a string to be able to communicate with Form2. Like if I click on button1 then it will be

textBox1.Text = myString; // this is form 2's textBox.

And I heard something about Global Variables, but I've been searching around, but I didn't find anything. So does anyone know how I can get myString from Form1 to Form2 ?

 

This is realy easy, you can create a new class, let's call it MyClass

in MyClass, create a public string and name in something (e.g myString)

Code:

using System;
using System.Collections.Generic;
using blah blah blah...

namespace FormsApp
{
    class MyClass
    {
           public static string MyString;
    }
}

then in Form1

Code:

private void button1_click(object sender, EventArgs e)
{
MyClass.myString = textBox1.Text;
}

and from Form2 (let's say we want the text in textbox1 as a title on form2..

Code:

private void Form2_load(object sender, EventArgs e)
{
   this.Title = MyClass.myString;
}

it's easy as that...
don't just copy and past cause it probably wont work since i wrote it in the reply box so probably some wrong casing or misspelling, but I guess you can figure it out

 

In any class (outside of a method), make sure you have a public static variable, and it will be global.
