使用TextFieldParser多数民众赞成内置到 VB.NET.谷歌找到了我这个例子

Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser _
  ("C:\test\info.csv")

  'Specify that reading from a comma-delimited file'
  MyReader.TextFieldType = FileIO.FieldType.Delimited
  MyReader.SetDelimiters(",")

  Dim currentRow As String()
  While Not MyReader.EndOfData
    Try
      currentRow = MyReader.ReadFields()
      With Me.dgvReport.Rows
        .Add(currentRow) 'Add new row to data grid view'
     End With
   Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException
     MsgBox("Line " & ex.Message & _
       "is not valid and will be skipped.")
   End Try
 End While
End Using
