I am trying to write a script that reads a xls file that the user uploaded on a page. The input looks like this:
<body>
<form id="uploadForm" runat="server">
<div>
<input type="file" id="UpdateFile" runat="server" />
</div>
<div>
<asp:Button runat="server" ID="submitFile" Text="Submit" OnClick="SubmitButton_Click"/>
</div>
</form>
<h3 id="message" runat="server"></h3>
</body>
protected void SubmitButton_Click(object sender, EventArgs e)
{
if (UpdateFile.PostedFile != null)
{
var file = UpdateFile.PostedFile;
....
I'm trying to figure out how to read this file line by line. I saw this post suggesting using ExcelPackage but I can't figure out how to add ExcelPackage to my project. I used the NuGet package manager to add ExcelPackage to my project but my code isn't recognizing it, ExcelPackage isn't showing up in my references even though I added it through NuGet.
