1 \t a
2 \t b
3 \t c
4 \t d

i have dataset: DataSet ZX = new DataSet();

is there any way for inserting the text file values to this dataset ?

thanks in advance

Answer 1

You will have to parse the file manually. Maybe like this:

string data = System.IO.File.ReadAllText("myfile.txt");

DataRow row = null;
DataSet ds = new DataSet();
DataTable tab = new DataTable();

tab.Columns.Add("First");
tab.Columns.Add("Second");

string[] rows = data.Split(new char[] { '\n' }, StringSplitOptions.RemoveEmptyEntries);
foreach (string r in rows)
{
    string[] columns = r.Split(new char[] { '\t' },   StringSplitOptions.RemoveEmptyEntries);
    if (columns.Length <= tab.Columns.Count)
    {
        row = tab.NewRow();

        for (int i = 0; i < columns.Length; i++)
            row[i] = columns[i];

         tab.Rows.Add(row);
     }
 }

 ds.Tables.Add(tab);

UPDATE

If you don’t know how many columns in the text file you can modify my original example as the following (assuming that the number of columns is constant for all rows):

// ...
string[] columns = r.Split(new char[] { '\t' },  StringSplitOptions.RemoveEmptyEntries);
if (tab.Columns.Count == 0)
{
    for(int i = 0; i < columns.Length; i++)
        tab.Columns.Add("Column" + (i + 1));
}

if (columns.Length <= tab.Columns.Count)
{
// ... 

Also remove the initial creation of table columns:

// tab.Columns.Add("First");
// tab.Columns.Add("Second")
