I have a format of String , for example:
However, instead of x you can enter several letters or numbers, for example:
What I need to do is compare to see if the format is the same, but the value does not matter.
Using Regex.IsMatch() you can check if a string is within the expected pattern, below is an implementation.
Do not forget to include the namespace System.Text.RegularExpressions
using System.Text.RegularExpressions;
string pattern = @"^.{4}-.{4}-.{3}$";
string[] input = { "A216-0450-013" , "X2LP-1018-589", "Y585-0000-047" , "585-0000-047" };
foreach(var item in input)
{
if(Regex.IsMatch(item,pattern))
Console.WriteLine("{0} is Match",item);
else
Console.WriteLine("{0} does not Match",item);
}
