I want to insert data from an Excel file into an SQL table, by matching the column names in the Excel file with the field names in the table. For instance, in my page (form?), I have a drop-down list containing a list of table names from the SQL DB, from which a user can select one as the destination. Into this table, I want to insert data from an Excel file, matching columns with field names. Please point me to some samples.
Thanks.

SQL

BULK INSERT MyTable FROM 'D:\myexcel.csv'
WITH
(
	FIRSTROW=2,
	FIELDTERMINATOR=',',
	ROWTERMINATOR='\n' 
)

Your table must match exact column sequence as you have in Excel.

Here is how can do so.

C#

private void button1_Click(object sender, EventArgs e)
{
	try {
		DataTable sheetTable = loadSingleSheet("C:\\excelFile.xls", "Sheet1$");
		updateDataTable(sheetTable);
	} catch (Exception ex) {
		System.Response.Write(ex.Message);
	}
}

public void updateDataTable(DataTable dt)
{
	using (SqlConnection connection = new SqlConnection(connectionString)) {
		SqlDataAdapter adapter = new SqlDataAdapter();
		DataSet ds = new DataSet();
		ds.Tables.Add(dt);
		adapter.Update(ds);
	}
}

private OleDbConnection returnConnection(string fileName)
{
	return new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + "; Jet OLEDB:Engine Type=5;Extended Properties=\"Excel 8.0;\"");
}

private DataTable loadSingleSheet(string fileName, string sheetName)
{
	DataTable sheetData = new DataTable();
	using (OleDbConnection conn = this.returnConnection(fileName)) {
		conn.Open();
		// retrieve the data using data adapter
		OleDbDataAdapter sheetAdapter = new OleDbDataAdapter("select * from [" + sheetName + "]", conn);
		sheetAdapter.Fill(sheetData);
	}
	return sheetData;
}

It might need some tuning but this is how you will do basically.
