OLEDB for EXCEL - Drop Table [SheetName$] - Doen't Delete Sheet

I am using drop table [SheetName$] to delete a worksheet from excel.

This just clears the data of the sheet but does not delete the sheet.

I have tried using xls and xlsx. Doesn't work with both versions !

OleDbConnection connection = new OleDbConnection();

try
{
connection.ConnectionString =
@"Provide开发者_JS百科r=Microsoft.ACE.OLEDB.12.0;Extended Properties='drop.xlsx";
connection.Open();
OleDbCommand command = new OleDbCommand("Drop Table [MySheetName_1$]", connection);
command.ExecuteNonQuery();
}
finally
{
connection.Close();
}

Any Help / Pointers appreciated ! Thanks

Unfortunately, you cannot delete a worksheet using ADO.NET for Excel. Instead, you will need to use the Excel Interop to perform this task. The basic code for the actual DELETE statement would look something like this:

using MSExcel = Microsoft.Office.Interop.Excel;

private MSExcel._Application excel;
private MSExcel._Workbook workbook;
private MSExcel._Worksheet worksheet;
private MSExcel.Sheets sheet;

Excelapp.DisplayAlerts = false;
((Excel.Worksheet)workBook.Worksheets[3]).Delete();
Excelapp.DisplayAlerts = true;

This is the basic rundown of how it would look. The DisplayAlerts lines are to fix an issue some people had with deleting a sheet. Also note that you cannot delete the last sheet in the Excel file. That issue will get you if you don't watch it.
