.net unicode汉字互相转换

【两种方法】.net unicode汉字互相转换

=========================================

//汉字转Unicode编码(ASCII)

private string StringToUnicode(string srcText)

        {

            string dst = "";

            char[] src = srcText.ToCharArray();

            for (int i = ; i < src.Length; i++)

            {

                byte[] bytes = Encoding.Unicode.GetBytes(src[i].ToString());

                string str = @"\u" + bytes[].ToString("X2") + bytes[].ToString("X2");

                dst += str;

            }

            return dst;

        }

//TO汉字 srcText为去除\u之后的4位字符

using System.Globalization;

private string ToCN(string srcText)

        {

            string str = srcText;

            byte[] bytes = new byte[];

            bytes[] = byte.Parse(int.Parse(str.Substring(, ), NumberStyles.HexNumber).ToString());

            bytes[] = byte.Parse(int.Parse(str.Substring(), NumberStyles.HexNumber).ToString());

            return Encoding.Unicode.GetString(bytes);

        }
