Passing value across methods

[yonelay]

namespace Sample1

{

public partial class MainForm : Form

{

private int field1;

public MainForm()

{

InitializeComponent();

field1 = 2;

}

private void button1_Click(object sender, EventArgs e)

{

if (field1 == 2)

{

do something here;

}

else

do other;

}



How can I get the field1 value to be 2 when button1_Click method is called? Right now everytime I call field1, I get null value. I'd like to recall the value that is assigned in one method to another method. Thanks for your answer.

I don't see anything wrong with that code with the exception of some missing } at the end...

There must be something else that is throwing the null reference exception...

It is impossible for field1 to be null as it is an int and therefore the compiler will automatically give it a zero value?.... As JurkMonkey said, something else is wrong here. Could you paste the code that is calling it?

As an added note, if it was declared an int? (with the questionmark) then it could be null.

? <- this makes any primitive data type nullable.
