2个字符串肉眼看着一样，但是实际长度不相等的情况记录

            string t1 = "bedf812f-2311-4717-a749-8b1272fc3c86";
            string t2 = "bedf812f-2311-4717-a749-8b1272fc3c86";

            var len1 = t1.Length;
            var len2 = t2.Length;

            if (t1 == t2)
            {
                Console.WriteLine("相同");
            }
            else
            {
                Console.WriteLine("不同");
            }
