Hey try the below code or do you have any pattern?

public static string AlphaNumericNo(int length = 16)
{
string cAlphaNumericCharacters = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
string sAlphaNumericNo = string.Empty;
for (int i = 0; i < length; i++)
{
string character = string.Empty;
do
{
int index = new Random().Next(0, cAlphaNumericCharacters.Length);
character = cAlphaNumericCharacters.ToCharArray()[index].ToString();
} while (sAlphaNumericNo.IndexOf(character) != -1);
sAlphaNumericNo += character;
}
return sAlphaNumericNo;
}
