Processing delimited file into a database

I have several semicolon-delimited files which contain hundreds of thousands of records in each. My objective is to reliably import them into a MS SQL database that I set up. I figured the easiest way to do this was to write a simple VB.NET application to process it.

The tricky part is that the values in the columns are not contained in quotes, and the last column has values that actually contain semicolons. There are a total of 5 columns.

Does anyone have recommendations on how I can best import these files into MS SQL?

If you know that columns 1 through 4 will not contain semicolons, you can reliably use the Split() function on the semicolon to break the rows down into values, since you will know that the first 4 members of the array will map to columns 1 through 4, and that all indexes after 3 (the fourth index in the array) need to be concatenated back into column5, below is a prototype of that scenario....
 

        Dim sr As New IO.StreamReader("c:\somefile.txt")

        While Not sr.EndOfStream
            Dim values() As String = Split(sr.ReadLine, ";")
            For i = 0 To 3 'These are the first 4 columns
                'Do something values(i)
            Next
            Dim col5 As String = String.Empty
            For i = 3 To UBound(values) ' These will all be parts of column 5
                col5 &= values(i)
            Next
            'Do something with col5 here then move on to the next row
        End While

Oops... that should actually be:
For i = 4 To UBound(values) ' These will all be parts of column 5
                col5 &= values(i)
Next

Can you not use the Import/Export wizard?

Kaufmed: I can't. The import/export wizard is unreliable. I tried it initially but as expected it failed with cryptic error messages.
