How to Create & Apply Line/Border Style in an Excel Comment?

We need to attach one more namespace OfficeOpenXml.Drawing.Vml, because in this code we can see LineWidth, LineColor, LineStyle properties. These properties belong to ExcelVmlDrawingComment class & ExcelComment class is inherited from

ExcelVmlDrawingComment class so, that's why the object of ExcelComment class gets those properties from his base class.

Please see this below code.

using(ExcelRange Rng = wsSheet1.Cells["B15"]) {
    ExcelComment cmd = Rng.AddComment("Comment Text", "Rajdip");
    cmd.Font.Bold = true;
    cmd.Font.Color = Color.Blue;
    //Apply Line or Border Style in Excel Comment.
    cmd.LineWidth = 3;
    Color GreenHexCode = ColorTranslator.FromHtml("#008000");
    cmd.LineColor = GreenHexCode; //Color.Green;
    cmd.LineStyle = eLineStyleVml.DashDot;
    cmd.Visible = true;
}

We can use custom color code by using ColorTranslator static class methods,

• FromHtml (string htmlColor), 
• FromOle (int oleColor), 
• FromWin32 (int win32Color).

return type of these methods are Color struct object.

There is another enum eLineStyleVml is used in this above code. This enum has eight enumerator list. These are



Here, I am using DashDot, that means 4 within enumerator list.

The output of Code,

            ExcelPkg.SaveAs(new FileInfo(@ "D:\FormatComments.xlsx"));
        }
    }
}
