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 
a) FromHtml (string htmlColor), 
b) FromOle (int oleColor), 
c) 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.

            }

            using (ExcelRange Rng = wsSheet1.Cells["B5"])
            {
                Rng.Style.Font.Size = 20;
                Rng.Value = "Excel Comment Border Style";

                ExcelComment cmd = Rng.AddComment("Comment Text", "Rajdip");
                cmd.Font.Bold = true;
                cmd.Font.Color = Color.Blue;

                cmd.Visible = true;
            }

            wsSheet1.Cells[wsSheet1.Dimension.Address].AutoFitColumns();
            ExcelPkg.SaveAs(new FileInfo(@"D:\FormatComments.xlsx"));
        }
    }
}

• Now build & execute this code. The file is (FormatComments.xlsx) store on D: drive of the computer.
