See more ULID/UUID Examples

Checks to see if a ULID is valid.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

C#

Chilkat.CkDateTime dt = new Chilkat.CkDateTime();

// A ULID must be exactly 26 chars in length,
// and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
// Note: The ULID alphabet excludes the letters I, L, O, and U

// Here's a valid ULID
string ulid = "01GRGCH4J88RECEN4D4VK4F629";
bool valid = dt.UlidValidate(ulid);
Debug.WriteLine("valid: " + Convert.ToString(valid));

// Here's an invalid ULID
ulid = "71GRGxx4Jr8RECEN4D4VK4F62!";
valid = dt.UlidValidate(ulid);
Debug.WriteLine("valid: " + Convert.ToString(valid));
