C# CSV文件导入数据库

做CSV导入数据库，一般是采用逐行读取，数据连接读取，再有这个通过引用Microsoft.VisualBasic.FileIO.TextFieldParser

其它方法我没试过，有朋友可以提示一下，非常感谢。逐行读取方法比较傻，数据连接读取效率高,通过TextFileParser这个方法比较特殊吧，今天刚发现，感觉不错。

1.通过数据连接读取

 1:  private void button1_Click(object sender, EventArgs e)

 2:  {

 3:      subImportCsv_Dataset("f:\\", "jjj.csv");

 4:  }

 5:  public void subImportCsv_Dataset(string filePath, string fileName)

 6:  {

 7:      string strConn = @"Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=";

 8:      strConn += filePath;//这个地方只需要目录就可以了                                                      

 9:      strConn += ";Extensions=asc,csv,tab,txt;";

10:      OdbcConnection objConn = new OdbcConnection(strConn);

11:      DataSet ds = new DataSet();

12:      try

13:      {

14:          string strSQL = "select * from " + fileName;//文件名，不要带目录

15:          OdbcDataAdapter da = new OdbcDataAdapter(strSQL, objConn);

16:          da.Fill(ds);

17:          //开始导入数据库

18:      }

19:      catch (Exception ex)

20:      {

21:          throw ex;

22:      }

23:  }

 

2.通过TextFileParser读取

 1:  private void subImportCSV_FileIo(string strFile)

 2:  {

 3:      Microsoft.VisualBasic.FileIO.TextFieldParser TF = new Microsoft.VisualBasic.FileIO.TextFieldParser(strFile, Encoding.GetEncoding("GB2312"));

 4:      TF.Delimiters = new string[] { "," }; //设置分隔符

 5:      string[] strLine;

 6:      while (!TF.EndOfData)

 7:      {

 8:          try

 9:          {

10:              strLine = TF.ReadFields();

11:              //开始导入数据库,这个地方要排除行头

12:          }

13:          catch

14:          {

15:          }

16:      }

17:      TF.Close();

18:  }
