c# unicode 编码 中文转换 已测试（转）

    中文传参时因为编码不同经常凌乱风中，故传前编成unicode码来过度是一个不错的解决方法

        public static string unicode_0(string str)
        {

            if (!string.IsNullOrEmpty(str))
            {
                for (int i = 0; i < str.Length; i++)
                {
                    outStr += "/u" + ((int)str[i]).ToString("x");
                }
            }
            return outStr;
        }
        /// <summary>

            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;

            }
            return outStr;
