Hi
I am trying to find a way to write VB.net code that can convert any text file into a DataTable
I found the following example that uses a comma delimeter. Is  there a way to detect the delimiter?


Dim dt As New DataTable()
dt.Columns.Add("Row No", GetType(Int32))
dt.Columns.Add("Col No", GetType(Int32))
dt.Columns.Add("Width", GetType(Int32))
dt.Columns.Add("Height", GetType(Int32))
dt.Columns.Add("ImageUrl", GetType([String]))
dt.Columns.Add("Description", GetType([String]))
Using sr As New StreamReader("D:\Temp\fileread\readtext.txt")
      While (InlineAssignHelper(line, sr.ReadLine())) IsNot Nothing
            Dim parts As String() = line.Split(","C)
            Dim dr = dt.NewRow()
            'use newrow to create new row
            For i As Integer = 0 To parts.Length - 1
                  dr(i) = parts(i)
            Next
                  'add row to datatable now
            dt.Rows.Add(dr)
      End While
      sr.Close()
End Using

instead of passing "," , you could pass sn char array of the couple of potential delimiters
with then the issue that none of those characters may appear in the data itself

otherwise you could write a detector function to check on a couple of lines how many times each of the potential delimiters appears...
