Efficient way to check if DataTable has row

Question

I have a function that search for a keyword and then return DataTable. I want to check if there rows inside because sometimes there's no query found.

    'which one shoud I use ?
    If dtDataTable Is Nothing Then
        'some code
        lbl_count.Text = "Found 0 result"
    End If

    If dtDataTable.Rows.Count > 0 Then
        'some code
        lbl_count.Text = "Found " & dtDataTable.Rows.Count.ToString & " results"
    End If

Thanks.

Answer 1

How about:

If dtDataTable IsNot Nothing AndAlso dtDataTable.Rows.Count > 0 Then
    'some code
    lbl_count.Text = "Found " & dtDataTable.Rows.Count.ToString & " results"
Else
    'some code
    lbl_count.Text = "Found 0 result"
End If

If you're using VB 9.0 (VS 2008) you can simply this with the following

lbl_count.Text = String.Format("Found {0} result(s)", if(dbDataTable, dbDataTable.Rows.Count,0))
