Workbook Opening Opening from Stream or Byte Array
In addition to opening from disk, SpreadsheetGear can also open from a memory stream or byte array using the IWorkbooks.OpenFromStream(...) and OpenFromMemory(...) methods. You can access IWorkbooks and these methods by first creating an IWorkbookSet, as demonstrated below.
// First create an empty workbook set. SpreadsheetGear.IWorkbookSet workbookSet = SpreadsheetGear.Factory.GetWorkbookSet(); // Open workbook file from a stream SpreadsheetGear.IWorkbook workbook = workbookSet.Workbooks.OpenFromStream(stream); // Open workbook file from a byte array SpreadsheetGear.IWorkbook workbook = workbookSet.Workbooks.OpenFromMemory(bytes);
