    public class MyString
    {
        private string _Value;

        //將建構子設為私有，代表無法用new關鍵字 
        private MyString(string value)
        {
            _Value = value.Trim();
        }

        //隱含轉換 接受string型別
        public static implicit operator MyString(string expandedName)
        {
            return new MyString(expandedName);
        }

        //隱含轉換 回傳string型別
        public static implicit operator string(MyString me)
        {
            return me._Value;
        }

        public override string ToString()
        {
            return _Value;
        }
    }


// Test code:
MyString str1 = "123 ";   //字尾有空白
tring x1 = str1;          //字尾無空白
