如何更改MS Excel单元格中文本的颜色? [英] How can I change color of text in a cell of MS Excel?

问题描述

我正在使用Microsoft.Office.Interop.Excel库.

我有一个值为绿色红色"的单元格.我想要的很简单.我想插入绿色"文本为绿色，插入红色"文本为红色，如下所示:

I have a cell with values "Green Red". What I want is pretty simple. I want to insert "Green" text to be green and "Red" to be red, like that:

我正在使用以下代码在单元格中插入数据:

I am using this code to insert data in cell:

Excel.Application excelApp = new Excel.Application();
excelApp.Workbooks.Add();
// single worksheet
Excel._Worksheet workSheet = excelApp.ActiveSheet;

for (int startIndex = 0; startIndex < 10; startIndex++)
{
    workSheet.Cells[1, (startIndex + 1)] ="Green" + " Red";
}

该怎么做?

我已经尝试了这种方法，但是我不知道什么是[RangeObject]:

I've tried this approach, but I do not know what [RangeObject] is:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

推荐答案

尝试:

workSheet.Cells[1, (i + 1)].Characters[start_pos, len].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

其中start_pos和len是字符串中要应用颜色的部分.

where start_pos and len is the part of the string where to apply color.

您的用例示例:

    Application excelApp = new Application();
    excelApp.Workbooks.Add();
    // single worksheet
    _Worksheet workSheet = excelApp.ActiveSheet;

    string Green = "Green";
    string Red = "Red";
    for (int start = 0; start < 10; start++)
    {
        Range ColorMeMine = workSheet.Cells[1, (start + 1)];
        ColorMeMine.Value = string.Format("{0} {1}", Green, Red);
        ColorMeMine.Characters[0, Green.Length].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Green);
        ColorMeMine.Characters[Green.Length + 1, Green.Length + 1 + Red.Length].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
    }
