Well, then stop development of Windows Form application. Stop it all and start reading some language and .NET manual, some general programming topics. Start with elementary problems, perhaps, writing some simple console-only applications as exercises. Seriously, everything else will be just a waste of time, including reading any answers you might get — it cannot help you.

Sad but true

:-( :-( :-( (This is the link; please see :-)
But actually this is not so sad. Take a break and learn, isn't that a good thing?

How about showing us the code (not too much) you are working with ? Where is the definition of the Class in which you want to access the value ? Where are instances of that Class created in your project ?

It's likely that OP can show some code, but unlikely that he clearly understands instances and classes to answer your questions — such people nearly always know how to access a member. Let's see though...

Solution 1

A public variable, say myvar, is accessible if you can access an instance of the form, say Form1, this way:

C#

Form1.myvar

That said, it is not a very good idea exposing member variables such a way. As other suggested, you should study a good book on Object Oriented Programming (and possibly on C#)

Hi, I'm not down-voting your answer, but I do think this is a confusing answer, particularly for a newcomer who is obviously not "at home" in .NET, and may be relatively new to the whole idea of semantic scope in OOP.

Thank you for your comment. Don't be afraid to downvote my answer if you think it is not helpful.

using System;
using System.Windows.Forms;

class form1:Form{
public  string variablename=""; // here you are declaring a variable 
//

here your code

//
}
First Create a object of that form class and using that object  you can call a variable

Form1 form=new Form1();
string str=form.variablename;     // here we can call that variable  using object of that class and store it into another variable
