I'm using this code to open an excel file and save it in a DataGridView:
string name = "Items";
string constr = "Provider = Microsoft.Jet.OLEDB.4.0; Data Source=" + Dialog_Excel.FileName.ToString() + "; Extented Properties =\"Excel 8.0; HDR=Yes;\";";
OleDbConnection con = new OleDbConnection(constr);
OleDbDataAdapter sda = new OleDbDataAdapter("Select * From [" + name + "$]", con);
DataTable data = new DataTable();
sda.Fill(data);
grid_items.DataSource = data;
As explained on: This youtube link
But I get an ISAM error. Any suggestion?
Since you have not replied to my comment above, I am posting a solution for both.
You are missing '
in Extended Properties
For Excel 2003 try this (TRIED AND TESTED)
private void button1_Click(object sender, EventArgs e)
{
String name = "Items";
String constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
"C:\\Sample.xls" +
";Extended Properties='Excel 8.0;HDR=YES;';";
OleDbConnection con = new OleDbConnection(constr);
OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
con.Open();
OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
DataTable data = new DataTable();
sda.Fill(data);
grid_items.DataSource = data;
}
BTW, I stopped working with Jet longtime ago. I use ACE now.
private void button1_Click(object sender, EventArgs e)
{
String name = "Items";
String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
"C:\\Sample.xls" +
";Extended Properties='Excel 8.0;HDR=YES;';";
OleDbConnection con = new OleDbConnection(constr);
OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
con.Open();
OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
DataTable data = new DataTable();
sda.Fill(data);
grid_items.DataSource = data;
}
For Excel 2007+
private void button1_Click(object sender, EventArgs e)
{
String name = "Items";
String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
"C:\\Sample.xlsx" +
";Extended Properties='Excel 12.0 XML;HDR=YES;';";
OleDbConnection con = new OleDbConnection(constr);
OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
con.Open();
OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
DataTable data = new DataTable();
sda.Fill(data);
grid_items.DataSource = data;
}
