EPPlus Excel Change cell color

Question

I am trying to set the color of a given cell with the color of another cell (that is already colored in the template. But worksheet.Cells[row, col].Style.Fill.BackgroundColor doesn't seem to have a getproperty. Is it possible to do that or do I have to find the exact hexdecimal code of the color on the internet ?

EDIT

using the code in the answer, I get that error (it is written in French but it translate with what I wrote in my first comment)

Answer 1

这样的事情怎么样？

//get color from this cell
var rgb = ws.Cells[1, 2].Style.Fill.BackgroundColor.Rgb;
//Convert to system.drawing.color
var color = System.Drawing.ColorTranslator.FromHtml("#" + rgb);
//set color in this cell
ws.Cells[1, 1].Style.Fill.PatternType = ExcelFillStyle.Solid;
ws.Cells[1, 1].Style.Fill.BackgroundColor.SetColor(color);

更新：似乎如果您从系统颜色或调色板中选择一种颜色作为填充颜色，它可以正常工作。如果您在填充下拉列表中选择“主题颜色”之一，则.Rgb返回空字符串

//get style
var style = ws.Cells[400, 1].Style;

//If color from System colors or palette
if (!string.IsNullOrEmpty(style.Fill.BackgroundColor.Rgb))
{
   //Convert to system.drawing.colow
   var color = System.Drawing.ColorTranslator.FromHtml("#" + style.Fill.BackgroundColor.Rgb);
   //set color in this cell
   ws.Cells[1, 1].Style.Fill.PatternType = ExcelFillStyle.Solid;
   ws.Cells[1, 1].Style.Fill.BackgroundColor.SetColor(color);
}
else if (!string.IsNullOrEmpty(style.Fill.BackgroundColor.Theme))
{
   //No idea how to get color from Theme
}

我不确定它是否受支持......根据EPPlus Faqs：

库不支持什么（这些是最明显的功能）？[...] * 主题
