int.TryParse failing with Console.ReadLine() in C#
If I try the following code in a simple console application:
string input = Console.ReadLine();
bool isString = int.TryParse(input, out myid);
I receive an error saying "the best overloaded method match for 'int.TryParse(string out int)' has some invalid arguments. I cannot work out why. Can anyone shed any light on this please?
在将它传递给int.TryParse之前，需要将myid声明为int
int myid;
string input = Console.ReadLine();
bool isString = int.TryParse(input, out myid);
