Answer 1

Use String.TrimStart:

// s is string
string trimmed = s.TrimStart('0');

Please note that it is essential that you assign the result of String.TrimStart to a variable of type string. In .NET, strings are immutable and therefore String.TrimStart does not modify the string that the method is invoked on. That is, s.TrimStart('0') does not modify s. If you want to modify s you must say

s = s.TrimStart('0');
