Question

I am trying to use TryParse to find if the string value is an integer. If the value is an integer then skip foreach loop. Here is my code.

string strValue = "42 "

 if (int.TryParse(trim(strValue) , intVal)) == false
 {
    break;
 }

intVal is a variable of type int?(nullable INT). How can I use Tryparse with nullable int?

You can’t do this without using another variable, unfortunately – because the type of out arguments has to match the parameter exactly.

Like Daniel’s code, but fixed in terms of the second argument, trimming, and avoiding comparisons with Boolean constants:

int tmp;
if (!int.TryParse(strValue.Trim(), out tmp))
{
    break;
}
intVal = tmp;
