你要么使用

series1.Points(1).Format.Fill.ForeColor.RGB = System.Drawing.ColorTranslator.ToOle(Color.Green);

或

series1.Points(1).Format.Fill.ForeColor.RGB = Excel.XlRgbColor.rgbGreen

编辑：请注意，点是 1 索引而不是 0 索引。

它不喜欢 ToArgb（） 中的 A。 使用 & 运算符来摆脱它：

series1.Points(1).Format.Fill.ForeColor.RGB = Color.Green.ToArgb() & 0xffffff;
