Convert String.Empty to Nothing/Null

Question

Is there a .Net function that does that. I guess if there isn't i have to make my own method.

The thing is i have a function. It accepts integers. If you pass a 0 integer or a null value it still works. Problem is that the value of an empty textbox is a String.Empty value.

I don't want to use if's. I mean it could but its much nicer if i can just call my function like this

MyFunction(txtTextbox.Text) 

But it won't work because it can't convert the string.empty to a integer.

Answer 1

I guess you need:

if(string.IsNullOrEmpty(value)) value = null;

or

int MyFunction(string value)
{
     if(string.IsNullOrEmpty(value)) return 0;

     int val = 0;
     int.TryParse(value, out val);
     return val;
}
