i want to import data from an excel file into a temp table in sql and then display it in a gridview in asp.net.

What I have tried:

C#

SqlDataAdapter da = new SqlDataAdapter();

da.InsertCommand = new SqlCommand("SELECT * into #InsertQueues FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;HDR=NO;IMEX=1;Database= " + filePath + "'" + @"SELECT * FROM[" + getExcelSheetName + @"')");


da.SelectCommand = new SqlCommand("Select * from #InsertQueues");

vid.Open();

da.InsertCommand.ExecuteNonQuery();

da.SelectCommand.ExecuteNonQuery();

DataSet ds = new DataSet();

da.Fill(ds);

GridView2.DataSource = ds;

GridView2.DataBind();

vid.Close();

Error: ExecuteNonQuery: Connection property has not been initialized.

ExecuteNonQuery: Connection property has not been initialized.

C#

da.SelectCommand = new SqlCommand("Select * from #InsertQueues", vid);

And no need to open and close the connection. SqlDataAdapter does this internally. Also, ExecuteNonQuery is not required here, everything is handled by Fill method.
