Question

Suppose I my project contains a Form and a Class. I would like to create a variable that can be accessed by both the Form and the class. In VB6 I could create a public variable in the (module / class), and easily access it like so:

VB6 Example

[Module code]

Public string_name as string

[/Module code]

[Form Code]

string_name = "test data"
MsgBox(string_name) ' Returns "test data"

[/Form Code]

How could I produce the above functionality with C#? I’m assuming I’d have to create a public class, but I’m not sure of the best way to declare public variables.

thank you,

You can do the same in c# (expose a field as public), though that is not good practice.

Use properties instead:

// public string property
public string string_name { get; set; }

// within class    
string_name = "test data";
MsgBox(string_name); 

// from another class
myClassInstance.string_name = "other test data";
