asp.net mvc用aspose.cells 导出xlsx格式的excel。无残留

public void Export()
{
HttpResponse Response = System.Web.HttpContext.Current.Response;
// Load your source workbook
Workbook workbook = new Workbook(); // Creating a Workbook object
var sheet = workbook.Worksheets[0];
sheet.Cells[0, 0].PutValue(1);
if (Response != null)
{
// Save in Xlsx format
workbook.Save(Response, "test.xlsx", ContentDisposition.Attachment, new OoxmlSaveOptions());
Response.End();
}
}
