Question

I have a similar requirement to this post…
Populate Gridview at runtime using textfile

Where I want to read a text file with StreamReader and populate a DataTable with the data in the file, however I’m not sure how to implement a split() with a tab.

Could anybody point me in the right direction, please?

You can try this:

        DataTable table = new DataTable();
        table.Columns.Add("col1");
        table.Columns.Add("col2");
        table.Columns.Add("col3");

        var lines = File.ReadAllLines(@"Data.txt").ToList();
        lines.ForEach(line => table.Rows.Add(line.Split((char)9)));

I presumed that rows are delimited by newline (if that’s the case ReadAllLines method can be used). Number 9 is the ASCII value for horizontal tab character and it is used for splitting the line. ForEach is a method that can be used on generic lists, it is there instead of the foreach loop.
