Question

Why can’t i change value with an if statement?

        int amount;
        string inputbalk = inputbar.Text;

        if (inputbalk== string.Empty)
        {
            amount = Convert.ToInt32(inputbalk);
            amount = 1;
        }

        if (inputbalk != string.Empty)
        {
            amount = Convert.ToInt32(inputbalk);
            amount = 1;
        }

        int onepercent = amount/= 100;

It will see “amount” as an unassigned variable, even though I set it to 1, by two different if-statements.

If I debug, I get this:
“Error 1 Use of unassigned local variable ‘amount'”

Thanks for help guys, It is fixed/solved.

Just change second if to else

        if (inputbalk== string.Empty)
        {
            amount = Convert.ToInt32(inputbalk);
            amount = 1;
        }
        else
        {
            amount = Convert.ToInt32(inputbalk);
            amount = 1;
        }

The compiler can’t make sure that one of two if statements will work anyway, so it will throw error that your variable amount can be unassigned.

In if/else notation one of two code blocks will be done anyway, so compiler will not throw error and everything will work as you want.
