C#半角字符和全角字符相互轉換函數代碼

這兩個C#函數分別用于將半角字符轉換成全角字符和將全角字符轉換成半角字符，調用簡單

/// <summary>
        /// 轉全角的函數(SBC case)
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        public static string ToSBC(string input)
        {
            //半角轉全角：
            char[] c = input.ToCharArray();
            for (int i = 0; i < c.Length; i++)
            {
                if (c[i] == 32)
                {
                    c[i] = (char)12288;
                    continue;
                }
                if (c[i] < 127)
                    c[i] = (char)(c[i] + 65248);
            }
            return new string(c);
        }
