//中文转为UNICODE字符

string str = "中文";

            string outStr = "";

            if (!string.IsNullOrEmpty(str))

            {                

                for (int i = 0; i < str.Length; i++)

                {

                    //将中文字符转为10进制整数，然后转为16进制unicode字符

                    outStr += "\\u" + ((int)str[i]).ToString("x");

                }

            }

//UNICODE字符转为中文

            string str = "\\u4e2d\\u6587";

            string outStr = "";

            if (!string.IsNullOrEmpty(str))

            {

                string[] strlist = str.Replace("\\","").Split('u');

                try

                {

                    for (int i = 1; i < strlist.Length; i++)

                    {

                        //将unicode字符转为10进制整数，然后转为char中文字符

                        outStr += (char)int.Parse(strlist[i], System.Globalization.NumberStyles.HexNumber);

                    }

                }

                catch (FormatException ex)

                {

                    outStr = ex.Message;
