How can I set the RGB Color in font Using xssfworkbook npoi

Question

How can I set the RGB color in cell backgroudn using class xssfworkbook using npoi?

byte[] rgb = new byte[3] { 192, 50, 90 };
XSSFCellStyle HeaderCellStyle1 = (XSSFCellStyle)wb.CreateCellStyle();
HeaderCellStyle1.SetFillForegroundColor(new XSSFColor(new Color(255, 255, 255)));

I don't want to use this pattern:

titlestyle.BottomBorderColor = IndexedColors.Grey25Percent.Index;

You have to make sure you cast your font to XSSFFont first, IFont does not offer access to the RGB color properties of the font.

You can then set the color using an XSSColor , which can either be constructed from a byte array or a System.Drawing.Color object.

Example code, different varieties of the constructor in comments:

var wb = new XSSFWorkbook();
var sheet = wb.CreateSheet("Sheet 1");

// Create a colored font
var font = (XSSFFont) wb.CreateFont();
// var color = new XSSFColor(ColorTranslator.FromHtml("#C88C14"));
// var color = new XSSFColor(new Color(255, 255, 255));
var color = new XSSFColor(new byte[] {200, 140, 20});
font.SetColor(color);

// Create a dedicated cell style using that font 
var style = wb.CreateCellStyle();
style.SetFont(font);

// Create some cell values
var row = sheet.CreateRow(0);
row.CreateCell(0).SetCellValue("Standard text");
var cell = row.CreateCell(1);
cell.SetCellValue("Colored text");

// Apply the cellstyle we created
cell.CellStyle = style;

    solution of your problem is here

    here simply define new xssfcolor and assign it to xssfcellstyle     


 var color = new XSSFColor(new byte[] { 0,255, 0 });
 var rowstyle =(XSSFCellStyle)wb.CreateCellStyle();
 rowstyle.SetFillForegroundColor(color)
