Question

I am new to C# and I need to be able to access a declared variable from Form1 to Form2. Variable example:

decimal Total = 0.00M;
Total will increase when user enters items.

I need Form2 to access the variable Total from Form1 once the user is finished entering items and once the user selects the method to pay I can zero Total in Form2.

How can I do this?

Answer 1

If Form1 has a reference to Form2, you can just access it as a variable. Like this:

public class Form1
{
  public decimal Total {get; set;}
}

public class Form2
{
  public Form2()
  {
    var form1 = new Form1();
    form1.Show();

    ..later, after use has done some work and you need the variable
    var total = form1.Total;
  }
}
