将数据写入到CSV文件中--出现“科学计数法”问题

标签：

1. 在数据后面加上"/t" 或者加上/r 进行转义

2. Ends.Write(retReader["Statis_dt"].ToString() + ","); Ends.Write(retReader["BranchCode"].ToString() + ","); Ends.Write(retReader["OrganCode"].ToString() + ","); Ends.Write(retReader["Iou_No"].ToString() + "/t,"); Ends.Write(retReader["Contract_No"].ToString() + "/t,"); Ends.Write(retReader["Repay_Term_No"].ToString() + ","); Ends.Write(retReader["Plan_Repay_dt"].ToString() + ","); Ends.Write(retReader["Act_Repay_dt"].ToString() + ","); Ends.Write(retReader["Repay_Capital"].ToString() + ","); Ends.Write(retReader["Loan_Bal"].ToString() + ","); Ends.Write(retReader["Next_Term_Repay_Capital"].ToString() + ","); Ends.Write(retReader["Repay_Status"].ToString() + ","); Ends.Write(retReader["InsertTime"].ToString() + ",");   

3.  private void WriteDataLines(StreamWriter streamWriter)

4.         {

5.             foreach (DataRow dataRow in _dataTable.Rows)

6.             {

7.                 foreach (DataColumn dataColumn in _dataTable.Columns)

8.                 {

9.                     WriteValue(streamWriter, dataRow[dataColumn.ColumnName].ToString()+"\r");

10.                 }

11.                 streamWriter.WriteLine();

12.             }

13.         }

14. Ends.Write(Ends.NewLine);
