EPPlus kullanarak Excel belgesini açma

Question

EPPlus başvuru/paketi kullanarak bir Excel belgesi açmaya çalışıyorum. Excel uygulamasının açılmasını sağlayamıyorum. Hangi kod eksik?

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; 
} 

Ben pck.open(newFile); denedi ama buna izin vermez ...

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"); 
}
