Help how to improve this code/make it more compact

[MrNorth]

Hi!

I am looking for ways to improve this block of code, similar kind of code is found throughout the application I am working on, and I wonder if there is a way to compact it, make it more readable and less error prone, maybe through some clever lablda syntax, extension methods etc?

private void CopyToExcelExecute() {
            StringBuilder sb = new StringBuilder();
            Clipboard.Clear();
            foreach (var row in SelectedBOMRows) {
                if (row.BOMRow.Position != null)
                    sb.Append(row.BOMRow.Position.ToString());
                else
                    sb.Append(";");
                sb.Append(";");

                sb.Append(row.BOMRow.Level.ToString());
                sb.Append(";");

                if (row.BOMRow.ArticleReference != null) {
                    sb.Append(row.BOMRow.ArticleReference.Object.ArticleNumber);
                    sb.Append(";");
                    sb.Append(row.BOMRow.ArticleReference.Object.Title.DisplayText);
                    sb.Append(";");
                    sb.Append(row.BOMRow.ArticleReference.Quantity.ToString());
                    sb.Append(";");
                }
                else
                    sb.Append(";;;");

                sb.Append(row.BOMRow.Remark.DisplayText);

                if (row.BOMRow.SectionReference != null) {
                    sb.Append(";");
                    sb.Append(row.BOMRow.SectionReference.Object.Title.ToString());
                }
                else
                    sb.Append(";");
                sb.Append(Environment.NewLine);
               
            }
            Clipboard.SetText(sb.ToString(), TextDataFormat.CommaSeparatedValue);
           
        }

I appreciate all assistance and input! Most of the code is boilerplate and I really wish I could remove the if/else checks and write some compact C# code instead...
