当对函数的返回值有多种需求时（执行是否成功，及业务数据的返回值），可采用的方法

Posted 2022-10-06 changbaishan

（1）bool+out

（2）返回值为实体模式：
 public  class DiskResult
   
        private bool successful;
        private string result;
        private string errorMessage;

        public bool Successful
       
            get
           
                return successful;
           

            set
           
                successful = value;
           
       

        public string Result
       
            get
           
                return result;
           

            set
           
                result = value;
           
       

        public string ErrorMessage
       
            get
           
                return errorMessage;
           

            set
           
                errorMessage = value;
