使用C#在Excel中进行条件格式设置 [英] Conditional Formatting in Excel with C#

问题描述

如果该值与另一列中的值不同，则需要对单元格的文本应用颜色.最好的方法是什么?我能想到的方法非常昂贵.

I need to apply a color to a cell's text if the value is not same as a value in another column. What would be the best approach for it ? The way I can think of is quite expensive.

 for (int i = 0; i < ColumnARange.Cells.Count; i++)
                    {
                        if (ColumnARange.Cells[i, 1] != ColumnBRange.Cells[i, 1])
                        {
                            Range currCell = ColumnBRange.Cells[i, 1];
                            currCell.Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
                        }
                    }

尝试如下条件格式，但徒劳无功.

Tried conditional formatting as below, but in vain.

FormatCondition cond = ColumnBRange.FormatConditions.Add(XlFormatConditionType.xlCellValue, XlFormatConditionOperator.xlNotEqual, ColumnARange);
                cond.Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

我正在使用VSTO，C#

推荐答案

以下代码将条件格式添加到D1到E10的单元格范围中

The following code, adds a conditional formatting to the cell range of D1 to E10

它分别比较值D1 = E1或D2 = E2.您可以设置字体颜色，或在FormatCondition对象上填充颜色.

It compares the values D1 = E1 or D2 = E2 respectively. you can set the font color, or color fill on the FormatCondition Object.

FormatCondition format =(FormatCondition)( targetSheet.get_Range("D1:E10",
                Type.Missing).FormatConditions.Add(XlFormatConditionType.xlExpression,
                                                   XlFormatConditionOperator.xlEqual,
                                                   "=$D1=$E1", 
                                                   Type.Missing, Type.Missing, Type.Missing,
                                                   Type.Missing, Type.Missing));
            
            format.Font.Bold = true;
            format.Font.Color = 0x000000FF;
