Hi,

I have a web page that allows a user to select an excel file using the
FileUpload Control (BrowseFileToUpload), then using a button's onclick
command (ButtonUploadFile_Click), uploads the selected file and saves it
using a preset name ("ExcelImportODS-" + u.UserName + ".xls") in a folder on
the webserver. 

Is there anyway to tell how many rows were in the uploaded file?

My upload is as follows:

    protected void ButtonUploadFile_Click(object sender, EventArgs e)
    {
        //Uploads the file selected by the user using the Browse button of
the fileupload control(CALLMaster\Data\TestImport.xls)
        //and uploads to web server using new name
ExcelImportODS-{webaccountname].xls.
        if (BrowseFileToUpload.HasFile)
        {
            try
            {
                String strFileExt =
System.IO.Path.GetExtension(BrowseFileToUpload.PostedFile.FileName);
                if (strFileExt == ".xls")
                {
                    try
                    {
                        String strSettingSelected = "";
                        if (RadioButtonListImportSetting.SelectedIndex == 1)
                        {
                            strSettingSelected = "Custom Settings";
                        }
                        else
                        {
                            strSettingSelected = "Fixed Settings";
                        }

                        MembershipUser u =
Membership.GetUser(User.Identity.Name);
                        //You can use the u.xxxxx method to access various
user info.  ex. u.email or u.lastactivitydate
                        //use intelisense for options.

BrowseFileToUpload.SaveAs(Server.MapPath("~/ImportData/ExcelImportODS-" +
u.UserName + ".xls"));
                        //LabelUploadStatus.Text = "<br>Uploaded File Name:
BrowseFileToUpload.PostedFile.ContentType + " File Size: " +
BrowseFileToUpload.PostedFile.ContentLength + "kb FileExtension: " +
strFileExt + "<br>";
                        LabelUploadStatus0.Text = "<br>Uploaded File Name: "
+ BrowseFileToUpload.PostedFile.FileName + "<br>" + " with " +
strSettingSelected + "<br>";
                        PanelBrowseUpload.Visible = false;
                        PanelViewImport.Visible = true;
                    }
                    catch (Exception ex)
                    {
                        LabelUploadStatus.Text = "Upload Error: " +
ex.Message.ToString();
                    }
                }
                else
                {
                    LabelUploadStatus.ForeColor = System.Drawing.Color.Red;
                    LabelUploadStatus.Text = "<br> * File Type Error: File
must be .xls.  File not uploaded.";
                }
            }
            catch (Exception ex)
            {
                LabelUploadStatus.Text = "Error: " + ex.Message.ToString();
            }
        }
        else
        {
            LabelUploadStatus.Text = "Please select a file to upload";
        }
    }

Hi Morris,

From your description the requirement is to know how many rows are there in
the uploaded xls file, right?
If so I think you can try Excel interop. Here's the code that demonstrates
how to do so. (Please add reference Microsoft.Office.Interop.Excel first)

Aspx:

        <asp:FileUpload ID="FileUpload1" runat="server"  />
        <asp:Button ID="Button1" runat="server" Text="Upload"
onclick="Button1_Click"  />

Aspx.cs:

using Excel = Microsoft.Office.Interop.Excel;

  static object mylock = new object();

        protected void Button1_Click(object sender, EventArgs e)
        {
        string extension= 
System.IO.Path.GetExtension(this.FileUpload1.FileName);
        if (extension.ToLower() == ".xls")
         {
             lock (mylock)
             {
                 string path = Server.MapPath("test.xls");
                 this.FileUpload1.SaveAs(path);
                 //get the total row number
                 Excel.Application app = new Excel.Application();
                 object missing = Type.Missing;
                 Excel.Workbook wb =
app.Workbooks.Open(Server.MapPath("test.xls"), missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing,
missing, missing, missing);
                 try
                 {

                     Excel.Worksheet ws = app.ActiveSheet as
Excel.Worksheet;
//Please notice the code demonstrates how to get the used row of the active
sheet.
//You can get the reference of the inactive sheets via app.Sheets collection
                     int total_rows= ws.UsedRange.Rows.Count;
                 }
                 finally
                 {
                     app.Quit();
                 }

             }
         }
        }

Please test the above code to see if it works.
