Set custom BackgroundColor of a Excel sheet cell using epplus c#

问题

The problem:

I am using EEPlus.

I am stuck at applying a hex color code, e.g. #B7DEE8, for a cell in my Excel sheet.

I got the following (working) code:

ws.Cells["A1:B1"].Style.Fill.PatternType = ExcelFillStyle.Solid;
ws.Cells["A1:B1"].Style.Fill.BackgroundColor.SetColor(Color.Gray);

But I need something like the following:

ws.Cells["A1:B1"].Style.Fill.BackgroundColor.SetColor("#B7DEE8");

So my question is: is it possible to use hex color codes with EEPlus? If so, how can I do that?

回答1:

Try this

Color colFromHex = System.Drawing.ColorTranslator.FromHtml("#B7DEE8");
ws.Cells["A1:B1"].Style.Fill.PatternType = ExcelFillStyle.Solid;
ws.Cells["A1:B1"].Style.Fill.BackgroundColor.SetColor(colFromHex);

This is working well.

Dim objExcel As New ExcelPackage
Dim Sheet As ExcelWorksheet = objExcel.Workbook.Worksheets.Add("SheetName")
Sheet.Cells["A1"].Style.Fill.PatternType = Style.ExcelFillStyle.Solid
Sheet.Cells["A1"].Style.Fill.BackgroundColor.SetColor(Color.FromArgb(170, 170, 170))

You are not obliged to translate a hexadecimal CSS color formula: You can simply put "0X" as a header of that number, which makes it an integer expression:

    var couleur = System.Drawing.Color.FromArgb(OXB7DEF8);
    Sheet.Cells["A1"].Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
    Sheet.Cells["A1"].Style.Fill.BackgroundColor.SetColor(couleur);
