RE: Application-wide Objects in Windows Forms Apps

Hello Alex,

Thanks for using Microsoft Newsgroup Support Service, my name is Ji Zhou
[MSFT] and I will be working on this issue with you.

Based on my understanding on your post, the objective is creating a global
accessible object that can be consumed in every forms in our windows form
application, right? If I have misunderstood, please feel free to let me
know.

Actually, if we want to share an object globally, we can put it in the
Program class as an public static class variable. The Program class is used
to hold the Main() function which is the entry of the whole application.
The following is what I have done on my side, and it works fine. Please let
me know if this addresses your issue.

1.I create a CustomClass using these codes,

class CustomClass
{
int x;
int y;

public CustomClass(int a, int b)
{
x = a;
y = b;
}

public int Add()
{
return x + y;
}
}

2.Create a public static class variable in the Program.cs file before the
Main function,

static class Program
{
public static CustomClass c = new CustomClass(3,4);

[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}

3.Then, we can access the variable c anywhere in the windows form
application project,
private void Form1_Load(object sender, EventArgs e)
{
Debug.Print(Program.c.Add().ToString());
Form2 f = new Form2();
f.Show();
}

private void Form2_Load(object sender, EventArgs e)
{
Program.c.Add();
}

Please let me know if you have any other questions or concerns on this, and
I will try my best to provide future help!
