Making only the Header row (row1) Bold in Excel [C#]

[Shaitan00]

Given an Excel File [Tasks.xls] that I create (as a kind of template) which has a Header row [row1, the first row in the Excel File]
So obviously I want to make that rows font BOLD, problem is when I use my current code (as shown below) it seems to make the entire range BOLD so the actual rows of information I add afterwards [row2+] are all BOLD also - not just the header row as I wanted.

oSheet.get_Range("A1", "G1").Font.Bold = true;

Is there a way maybe to set the Font cell by cell? [very easy to just manually set cells [1, 1-6] bold, I just dont want every subsequent row to also be bold.
Is there a way to set it only for row1? (cell by cell basis? row by row basis? of setting Font.Bold = true?)
Thanks,

There a a few different ways to accomplish this.
assuming o.Sheet is the Excel.Worksheet reference.
1. using the Range properity - oSheet.Range("A1:G1").Font.Bold = True
2. using a cell by cell loop

For i = 1 to 6
oSheet.Cells(1, i).Font.Bold = True
End For

3. specific cell referencing
oSheet.Cells(1, 1).Font.Bold = True

I hope this gives you an idea how to solve your task.

This is how I generate my oSheet

Excel._Worksheet oSheet = (Excel._Worksheet)oWB.Sheets["Sheet1"];

Sadly none of your 3 suggestions seem to work...
1. There is no oSheet.Range property (doesnt exist)
2/3. There is no .Cells().Font property (doesnt exist) AND it is .Cells[] not .Cells()

Any clues as to why? What I am doing wrong? Other ideas?
I find it really hard to beleive that there is no way to BOLD only certain rows or cells ...

Thanks,

Heres a suggestion for establishing an Excel worksheet.

Dim excelApp As New Excel.Application
If excelApp Is Nothing Then
    MessageBox.Show("Excel Installation Error", "Microsoft Excel must be installed on this computer for this feature to operate.")
End If

Cursor.Current = Cursors.AppStarting

Dim excelBook As Excel.Workbook = excelApp.Workbooks.Add
Dim excelWorksheet As Excel.Worksheet = CType(excelBook.Worksheets(1), Excel.Worksheet)
Dim row as Integer = 1

With excelWorksheet
    .Cells(row, 1).Value = "Add Something Here"
    .Cells(row, 1).HorizontalAlignment = Excel.XlHAlign.xlHAlignLeft
    .Cells(row, 1).Font.Bold = True
End With

OR

With excelWorksheet
    .Cells(row, 1).Value = "Add Something Here"
    .Cells(row, 1).HorizontalAlignment = Excel.XlHAlign.xlHAlignLeft
    .Range(row & "1:L1").Font.Bold = True you can write a function here to convert a numeric column number to a letter
End With

excelWorksheet.Columns.AutoFit()
Cursor.Current = Cursors.Default
excelApp.Visible = True

I hope this helps.
