I would use IO.StreamReader class to open the file, then read it into a
dataTable.
Here is the function that does just that in VB.Net (but it can be easily
converted to C# to suit your needs though
To use it, you do something like
Dim dt As DataTable = BuildDataTable("C:\myTestFile.txt", ",") 'for CSV file
Once you get this data table, you can do whatever you want with it... Each
datarow serves as one object in your question.
'Reading file to datatable
Private Function BuildDataTable(ByVal fileFullPath As String, ByVal
seperator As Char) As DataTable
Dim myTable As DataTable = New DataTable("MyTable")
Dim i As Integer
Dim myRow As DataRow
Dim fieldValues As String()
Dim f As IO.File
Dim myReader As IO.StreamReader
Try
'Open file and read first line to determine how many fields
there are.
myReader = f.OpenText(fileFullPath)
fieldValues = myReader.ReadLine().Split(seperator)
'Create data columns accordingly
For i = 0 To fieldValues.Length() - 1
myTable.Columns.Add(New DataColumn("Field" & i))
Next
'Adding the first line of data to data table
myRow = myTable.NewRow
For i = 0 To fieldValues.Length() - 1
myRow.Item(i) = fieldValues(i).ToString
Next
myTable.Rows.Add(myRow)
'Now reading the rest of the data to data table
While myReader.Peek() <> -1
fieldValues = myReader.ReadLine().Split(seperator)
myRow = myTable.NewRow
For i = 0 To fieldValues.Length() - 1
myRow.Item(i) = fieldValues(i).ToString
Next
myTable.Rows.Add(myRow)
End While
Catch ex As Exception
MsgBox("Error building datatable: " & ex.Message)
Return New DataTable("Empty")
Finally
myReader.Close()
End Try
Return myTable
End Function
Hope this helps.
