ExcelReaderFactory, reading first sheet

Question

I am using the ExcelDataReaderFactory in C#, in order to read my Excel files and inserting them to a database.
Right now I am specifying sheetname

Answer 1

I don't know that library. But I think you are converting it to a DataSet anyway. Then the first sheet/table is:

DataTable firstWorkSheet = reader.AsDataSet().Tables[0];

Since the indexer of DataTableCollection has an overload for the index not only for the name.

So the whole method is:

public IEnumerable GetFirstSheetData(bool firstRowIsColumnNames = false)
{
    var reader = this.getExcelReader();
    reader.IsFirstRowAsColumnNames = firstRowIsColumnNames;
    return reader.AsDataSet().Tables[0].AsEnumerable();
}
