使用EPPlus打开Excel文档

我正在尝试使用EPPlus参考/包打开Excel文档。 我无法打开Excel应用程序。 我错过了什么代码？

protected void BtnTest_Click(object sender, EventArgs e) { FileInfo newFile = new FileInfo("C:\\Users\\Scott.Atkinson\\Desktop\\Book.xls"); ExcelPackage pck = new ExcelPackage(newFile); //Add the Content sheet var ws = pck.Workbook.Worksheets.Add("Content"); ws.View.ShowGridLines = false; ws.Column(4).OutlineLevel = 1; ws.Column(4).Collapsed = true; ws.Column(5).OutlineLevel = 1; ws.Column(5).Collapsed = true; ws.OutLineSummaryRight = true; //Headers ws.Cells["B1"].Value = "Name"; ws.Cells["C1"].Value = "Size"; ws.Cells["D1"].Value = "Created"; ws.Cells["E1"].Value = "Last modified"; ws.Cells["B1:E1"].Style.Font.Bold = true; } 

我试过pck.open(newFile); ，但它不允许…

尝试这个：

 protected void BtnTest_Click(object sender, EventArgs e) { FileInfo newFile = new FileInfo("C:\\Users\\Scott.Atkinson\\Desktop\\Book.xls"); ExcelPackage pck = new ExcelPackage(newFile); //Add the Content sheet var ws = pck.Workbook.Worksheets.Add("Content"); ws.View.ShowGridLines = false; ws.Column(4).OutlineLevel = 1; ws.Column(4).Collapsed = true; ws.Column(5).OutlineLevel = 1; ws.Column(5).Collapsed = true; ws.OutLineSummaryRight = true; //Headers ws.Cells["B1"].Value = "Name"; ws.Cells["C1"].Value = "Size"; ws.Cells["D1"].Value = "Created"; ws.Cells["E1"].Value = "Last modified"; ws.Cells["B1:E1"].Style.Font.Bold = true; pck.Save(); System.Diagnostics.Process.Start("C:\\Users\\Scott.Atkinson\\Desktop\\Book.xls"); } 

希望这可以帮助！
