推荐答案

System.Drawing不会帮助改变excel单元格的颜色。您没有说明如何访问excel文件。但是，您正在访问excel文件（使用下面的互操作），您必须通过获取其范围来解决要更改颜色的单元格，然后根据需要设置内部颜色和字体颜色。示例：使用下面的互操作：

System.Drawing is not going to help changing the color of an excel cell. You do not say how you are accessing the excel file. However you are accessing the excel file (using interop below) you will have to address the cell you want to change the color by getting its range, then setting the Interior color and font color if needed. Example: using interop below:

Range range = MySheet.get_Range("B3");
string someValue = "ValueToFlag";
if (range.Value.ToString() == someValue) {
  range.Interior.Color = Color.Red;
  range.Font.Color = Color.Yellow;
}
else {
  range.Interior.Color = Color.White;
  range.Font.Color = Color.Black;
}
Console.ReadKey();
