Answer 1

Look at something like EPlus which seems to be a popular library.

... or FileHelpers, where there is a good quickstart showing you how to create a .csv file

You can just use the export functionality of Sql Server Management studio if it's a one off type job?

Answer 2

Best way is to use XmlSerialization of the data table and then perform Excel Loading of the serialised Xml...

There is a nice open source utility (which you can add to your project and make changes to as well) called ExcelLibrary ... please refer to this article... Create Excel (.XLS and .XLSX) file from C#

This is one of the most efficient ways of Bulk Excel Loading.

Here is how I solved this :

Private Function getData(ByVal query As String, ByVal conStr As String) As Object
    Dim adapter As New Data.OleDb.OleDbDataAdapter(query, conStr)
    Dim dataSet As New Data.DataSet
    adapter.Fill(dataSet)
    Dim dataTable As Data.DataTable = dataSet.Tables(0)
    Dim data(dataTable.Rows.Count, dataTable.Columns.Count - 1) As Object
    For col = 0 To dataTable.Columns.Count - 1
        For row = 0 To dataTable.Rows.Count - 1
            data(row, col) = dataTable.Rows(row).ItemArray(col)
        Next
    Next
    Return data
End Function

Then Finally, do the following to the range where you want to have this data

range.Value = getDate(query,conStr)

That solved the whole problem !

The simplest solution is if you write a csv file. In the csv the columns are separated with comma (;) and the excel can read this file.

The best way is the OLE Automation but for this you have to install an excel to the pc where your program runs. Here is a sample: OLE Automation
