Can't convert number to Int C#

I'm trying to make a small application. It gets an ID in a server response, but it's in string format. I need to convert it to int, but it doesn't seem to work. That ID is for example 76561198078450726. Int.TryParse returns 0.

Other methods doesn't work either. Do you have any Idea, whats the problem?

Edit: Thanks a lot for your helpful answers. I don't know, how I could miss that. Thanks!

Int32.MaxValue is 2,147,483,647. When TryParse fails it returns 0.

Try long.TryParse()

That's a really big number. Int only goes to 2147483647.

Use long or take a look at System.Numerics.BigInteger to go even bigger: https://msdn.microsoft.com/en-us/library/system.numerics.biginteger.aspx

Edit: Also, int.TryParse returns true or false and that is what you should be checking, not if the out value is 0. Because int i; int.TryParse("0", out i); is also completely valid.

Since int.MaxValue is 2147483647, this value is too large for an 32-bit signed integer. I would suggest to parse it to long instead.

long l = long.Parse("76561198078450726");

76561198078450726 is far outside the range of int (which is -2,147,483,648 to 2,147,483,647), use long instead:

if (long.TryParse(value, out myValue)) ...
