How to Fill a Datatable with a tab delimited text file in C#?

I want to fill a DataTable with a tab delimited Text file. The text file contains data as follows:

Name   Id   Place
Sam    2001   USA
Raja    3455   India
Allan    90101   Canada

When I use OleDBConnection to import the text file into the DataTable, I am getting data in DataTable as follows:

Name_Id_Place
Sam2001USA
Raja3455India
Allan90101Canada

The actual text file has 3 columns and 3 rows, but in the DataTable I got all 3 columns as a single column Name_Id_Place.

Can anyone tell me the solution for this problem?

Here I think you reading data from text file in right way, only problem I see that your used Provider cannot understand where a end of column, that why read all row as one column

I had exact same result when trying read data from text file with OleDBConnection.

In my connectionstring as Provider I used: 

Provider=Microsoft.Jet.OLEDB.4.0;

If you used same then you need only change "Format" options for this provider in Windows registry:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Jet \ 4.0 \ Engines \ Text

Then modify "Format" key to value="TabDelimited"

or if you want use some other delimiter character(for example ";") then Format = "Delimited(;)"

    static void Main()
    {
        //create a data table and add the column's
        DataTable table = new DataTable("table_name");
        table.Columns.Add("name", typeof (String));
        table.Columns.Add("id", typeof (Int32));
        table.Columns.Add("place", typeof (String));

        //start reading the textfile
        StreamReader reader = new StreamReader("file_to_read");
        string line;
        while ((line = reader.ReadLine()) != null)
        {
            string[] items = line.Split('\t');
            //make sure it has 3 items
            if (items.Length == 3)
            {
                DataRow row = table.NewRow();
                row["name"] = items[0];
                row["id"] = Int32.Parse(items[1]);
                row["place"] = items[2];
                table.Rows.Add(row);
            }
        }
        reader.Close();
        reader.Dispose();

        // make use of the table


        // when use is done dispose it
        table.Dispose();
    }
