Does anyone have a better way for knowing if a string contains an
int ?

bool IsInt(string valeur)
{
bool result = false;
try {
int.Parse(valeur);
result = true;
}
catch {}
return result;
}

You can use "is"

if (variable is int)
{
return true;
}


or just inline the "variable is int" in your code conditionals without calling a function. This also works for most types.

However, I have not found a good way to detect int? (nullable int) as a type like above. It does not find it; always returns false. Still looking.

Why answer on a 3 year old question with a WRONG answer?

The "is" test if something is already an int not whether
a string can be parsed to an int.
