使用EPPlus打开Excel文档

Question

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;
}

我试过了pck.open(newFile);,但它不允许......

试试这个:

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!
