Question

是否有人知道如何使用C＃更改powerpoint加载项中所选文本范围的颜色？

Answer 1

或只是：

Globals.ThisAddIn.Application.ActiveWindow.Selection.TextRange.Font.Color.RGB = c.ToArgb();

其中'c'是你的颜色元素。

Answer 2

好吧，如果你正在使用互操作......


 var app = new ApplicationClass();
 app.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
 var myPresentation = app.Presentations.Open("c:\\test.pptx",
 Microsoft.Office.Core.MsoTriState.msoFalse,
 Microsoft.Office.Core.MsoTriState.msoFalse,
 Microsoft.Office.Core.MsoTriState.msoTrue);

 var slide1 = myPresentation.Slides[1];
 var range = slide1.Shapes[1].TextFrame.TextRange;
 range.Font.Color.RGB = -654262273;

不要忘记

System.Runtime.InteropServices.Marshal.ReleaseComObject(<your com objects here>)

Answer 3

如果有人还在寻找解决方案：

我遇到了同样的问题。花了一些时间想出这个方法，

var paragraph1 = oTxtRange.Paragraphs(1);
paragraph1.Text = "Test ";
paragraph1.Font.Color.RGB = BGR(Color.Black);

var paragraph2 = oTxtRange.Paragraphs(2);
paragraph2.Text = "Application ";
paragraph2.Font.Color.RGB = BGR(Color.Green);

private int BGR(Color color)
{

 // PowerPoint's color codes seem to be reversed (i.e., BGR) not RGB, so we have  to  produce the color in reverse

 int iColor = (color.A << 24) | (color.B << 16) | (color.G << 8) | color.R;
 return iColor;
}

我希望这有帮助！
