Hi developer's
I have a great problem to load a csv file in datatable . A reason is csv file values are seprated by (;). and when I given a (;) in oledb or odbc delimiter they can not identified them and given a "Index 121 type error", so then i am create schema.ini file and save them in bin\debug folder of the project . but after that again csv file not load in datatable.
I also tell u that i m load a many csv file that have a diffrent name then. is it possible to not add a file name in schema.ini file.

my code of project is please read this

public static DataTable ParseCSV(string path)
       {

           if (!File.Exists(path))
               return null;

           string full = Path.GetFullPath(path);
           string file = Path.GetFileName(full);
           string dir = Path.GetDirectoryName(full);

           //create the "database" connection string
           string connString = "Provider=Microsoft.Jet.OLEDB.4.0;"
             + "Data Source=\"" + dir + "\\\";"
             + "Extended Properties=\"text;HDR=yes;FMT=Delimited\";";

           //create the database query
           string query = "SELECT * FROM " + file;

           //create a DataTable to hold the query results
           DataTable dTable = new DataTable();

           //create an OleDbDataAdapter to execute the query
           OleDbDataAdapter dAdapter = new OleDbDataAdapter(query, connString);

           try
           {
               //fill the DataTable
               dAdapter.Fill(dTable);
           }
           catch (System.Exception ex)
           {
               MessageBox.Show(ex.Message);
           }

           dAdapter.Dispose();

           return dTable;
       }

       private void button1_Click(object sender, EventArgs e)
       {
           try
           {
               DialogResult result = this.openFileDialog1.ShowDialog();
               if (result == DialogResult.OK)
               {
                   string filename = openFileDialog1.FileName;
                   textBox1.Text = filename;
               }
               else
               {
                   MessageBox.Show("dear user please select path");
               }
               DataTable dt = Form1.ParseCSV(textBox1.Text);

               dataGridView1.DataSource = dt.DefaultView;
           }
           catch (System.Exception ex)
           {
               MessageBox.Show(ex.Message);
           }
       }
