这是一个简单的C#类,它以编程方式创建Excel WorkBook并向其中添加两个工作表,然后填充两个工作表。最后,它将WorkBook保存到应用程序根目录中的文件中,以便您可以检查结果......
public class Tyburn1
{
object missing = Type.Missing;
public Tyburn1()
{
Excel.Application oXL = new Excel.Application();
oXL.Visible = false;
Excel.Workbook oWB = oXL.Workbooks.Add(missing);
Excel.Worksheet oSheet = oWB.ActiveSheet as Excel.Worksheet;
oSheet.Name = "The first sheet";
oSheet.Cells[1, 1] = "Something";
Excel.Worksheet oSheet2 = oWB.Sheets.Add(missing, missing, 1, missing)
as Excel.Worksheet;
oSheet2.Name = "The second sheet";
oSheet2.Cells[1, 1] = "Something completely different";
string fileName = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)
+ "\\SoSample.xlsx";
oWB.SaveAs(fileName, Excel.XlFileFormat.xlOpenXMLWorkbook,
missing, missing, missing, missing,
Excel.XlSaveAsAccessMode.xlNoChange,
missing, missing, missing, missing, missing);
oWB.Close(missing, missing, missing);
oXL.UserControl = true;
oXL.Quit();
}
}
要执行此操作,您需要向项目添加对Microsoft.Office.Interop.Excel的引用(您可能已经创建了这个,因为您创建了一个工作表)。
添加第二张表的声明是......
Excel.Worksheet oSheet2 = oWB.Sheets.Add(missing, missing, 1, missing)
as Excel.Worksheet;
'1'参数指定单个工作表,如果要一次添加多个工作表,则可以更多。
最后说明:声明oXL.Visible = false;告诉Excel以静默模式启动。

var groupedSheetList = UserData
.GroupBy (u => u.date)
.Select (grp => grp.ToList ())
.ToList ();
您可以尝试
using (var package = new ExcelPackage ())
{
foreach (var item in groupedSheetList) {
var workSheet = package.Workbook.Worksheets.Add (item[0].date);
}
}
