You could do

For Each row As DataRow In dt.Rows

    Dim line As String = ""

    For Each column As DataColumn In dt.Columns
        'Add the Data rows.
        line += "|" & row(column.ColumnName).ToString()
    Next

    'Add new line
    txt += line.SubString(1)  vbCr

Next

If File.Exists(fileloc) Then
    Using sw As StreamWriter = New StreamWriter(fileloc)
        sw.WriteLine(txt)
    End Using
End If

That way each new line is built as "|a|b|c". The SubString chops off the leading "|" before it is added to the output buffer. You might want to use StringBuilder instead of String. It's much faster when building strings usinc concatenation.

i need output in diz format

Sorry about that. My previous post had a typo. Try

For Each row As DataRow In dt.Rows

    Dim line As String = ""

    For Each column As DataColumn In dt.Columns
        'Add the Data rows.
        line += "|" & row(column.ColumnName).ToString()
    Next

    'Add new line
    txt += line.SubString(1) & vbCrLf

Next

If File.Exists(fileloc) Then
    Using sw As StreamWriter = New StreamWriter(fileloc)
        sw.WriteLine(txt)
    End Using
End If

Dim fileloc As String = "D:\floor.txt"

 Dim fileloc As String = "D:\floor.txt"

                    Using dt As New DataTable()

                        sda.Fill(dt)

Using cmd As New SqlCommand("SELECT (DM_Code + '| ' + DM_Name) FROM [AssetMgmt].[dbo].[Department_Master]")

change the sql statement like this then if u generate d text file
For Each row As DataRow In dt.Rows

                        For Each column As DataColumn In dt.Columns

                            txt += row(column.ColumnName).ToString()
                            'txt += Custodian_ID '|'+ Custodian_Name

                        Next
txt += vbCrLf
