int.TryParse syntatic sugar

Question

int.TryPrase is great and all, but there is only one problem...it takes at least two lines of code to use:

int intValue;
string stringValue = \"         


        

Answer 1

This answer is only for those who use at least C# 7.

You can now declare the out parameter inline.

int.TryParse("123", out var result);

Exemplary usage:

if (int.TryParse("123", out var result)) {
    //do something with the successfully parsed integer
    Console.WriteLine(result);
} else {
    Console.WriteLine("That wasn't an integer!");
}
