Each of the numeric types in C# has a Parse method that you can use when converting from string representations of a numeric value to an object of the appropriate numeric type.
Here are some examples:

| byte b1 = byte.Parse("200");sbyte sb1 = sbyte.Parse("-100");float f1 = float.Parse("1.2e-4"); |
If the string does not represent a value of the associated numeric type, or represents a numeric value that is outside the range of the type, a FormatException or OverflowException is generated.

| int n1 = int.Parse("3.4"); // FormatExceptionuint ui1 = uint.Parse("-1"); // OverflowException |
Numeric strings containing digit grouping (thousand separator) or decimal points are assumed to be in a format matching the current culture. E.g. ‘.’ for decimal symbol in the US, ‘,’ for decimal symbol in France.
