2.引用ChineseConverter.dll文件

3.编写代码

using Microsoft.International.Converters.TraditionalChineseToSimplifiedConverter;

        /// <summary> 
        /// 简体转换为繁体
        /// </summary> 
        /// <param name="str">简体字</param> 
        /// <returns>繁体字</returns> 
        public static string GetTraditional(string str)
        {
            string r = string.Empty;
            r = ChineseConverter.Convert(str, ChineseConversionDirection.SimplifiedToTraditional);
            return r;
        }
        /// <summary> 
        /// 繁体转换为简体
        /// </summary> 
        /// <param name="str">繁体字</param> 
        /// <returns>简体字</returns> 
        public static string GetSimplified(string str)
        {
            string r = string.Empty;
            r = ChineseConverter.Convert(str, ChineseConversionDirection.TraditionalToSimplified);
            return r;
        }
