C# 中SqlDataReader怎么获取列名

  SqlConnection thisConnection = new SqlConnection(ConfigurationManagerAppSettings["ConnectionString"]ToString());

            // Open connection

            thisConnectionOpen();

            // Create command for this connection

            SqlCommand thisCommand = thisConnectionCreateCommand();

            // Specify SQL query for this command

            thisCommandCommandText = sCommandText;

            // Execute DataReader for specified command

            SqlDataReader thisReader = thisCommandExecuteReader();

            // While there are rows to read

            //

            //

            View_LogDetailEntity = new List<CView_LogDetail>();//初始化集合

 string sColumnName = stringEmpty;

  while (thisReaderRead())

            {

                CView_LogDetail myCView_LogDetail = new CView_LogDetail();

                for (int i = 0; i < thisReaderFieldCount; i++)

                {

                      sColumnName = thisReaderGetName(i)Trim();

                }

           }
