c# short if statement not working with int? (int=null)

Question

I am trying to shorten my code by using short-if: ``` int? myInt=myTextBox.Text == "" ? null : Convert.ToInt32(myTextBox.Text); ``` But I'm getting the following error: Type of conditional expression cannot be determined because there is no implicit conversion between '' and 'int' The following works: ``` int? myInt; if (myTextBox.Text == "") //if no text in the box myInt=null; else myInt=Convert.ToInt32(myTextBox.Text); ``` And if I replace the 'null' in integer (say '4') it also works: ``` int? myInt=myTextBox.Text == "" ? 4: Convert.ToInt32(myTextBox.Text); ```

Accepted Answer

Try this instead :

```
int? myInt=myTextBox.Text == "" ? (int?)null : Convert.ToInt32(myTextBox.Text);
```
