打开的Xml样式颜色显示不正确

Question

我正在使用OpenXml for Office SDK创建电子表格。我无法使单元格背景颜色正常工作。 我尝试将背景色应用于任何显示为黑色的单元格。

这是我生成的xml摘录：

用于生成它的代码如下：

fillList只是颜色列表

            Fills fillsNode = new Fills() { Count = GetUint(_fillList.Count)};
            foreach (System.Drawing.Color color in _fillList) {
                fillsNode.AppendChild(GetFill(color.R, color.G, color.B));
            }
            stylesheet1.Append(fillsNode);

这些函数用于创建Fill对象，并将r，g和b值转换为格式化的十六进制字符串。这是我怀疑可能会出错的地方之一。

        private Fill GetFill(int r, int g, int b) {
            PatternFill pf1 = new PatternFill { PatternType = PatternValues.Solid };
            pf1.Append(new BackgroundColor() { Rgb = GetHexStringFromRgb(r, g, b)});
            Fill f1 = new Fill();
            f1.Append(pf1);
            return f1;
        }

        private string GetHexStringFromRgb(int r, int g, int b) {


            return $"FF{r.ToString("X2")}{g.ToString("X2")}{b.ToString("X2")}";
        }

任何帮助将不胜感激。
