尝试

try

static void Main()
        {

            string a = GetAutoNumber("1"); // PR001
            string a1 = GetAutoNumber("11");// PR011
            string a2 = GetAutoNumber("111");// PR111
            string a3 = GetAutoNumber("1111");// PR1111

        }
        public static string GetAutoNumber(string lastPRNo)
        {
            string prefix = "PR";
            string number = lastPRNo;
            if (lastPRNo.Length < 3)
            {
                number = "000" + lastPRNo;
                number = number.Substring(number.Length - 3, 3);
            }

            return prefix + number;
