Question

我在下面的法典中写道,要改变使用c#代码的平面电池的背景,但是没有发生:

//creating powerpoint aaplication
PowerPoint.Application pptApp = new PowerPoint.Application();
pptApp.Visible = Office.MsoTriState.msoTrue;
var pptPresent = pptApp.Presentations;
var fileOpen = pptPresent.Open(@file, Office.MsoTriState.msoFalse, Office.MsoTriState.msoTrue, Office.MsoTriState.msoTrue);
// getting first slide
PowerPoint.Slide objSlide = fileOpen.Slides[1];
PowerPoint.Shapes item = objSlide.Shapes;
// getting first shape
var shape1 = item[1];
// check if shape is table
if (shape1.HasTable == Office.MsoTriState.msoTrue)
{
    // change the table cell to red color
    shape1.Table.Cell(2, 5).Shape.Fill.BackColor.RGB = System.Drawing.Color.Red.ToArgb();
    // make it visible
    shape1.Fill.Visible = Office.MsoTriState.msoTrue;
}
// saving the ppt
fileOpen.SaveAs(openFolder + subStr + ".pptx",PowerPoint.PpSaveAsFileType.ppSaveAsDefault,Office.MsoTriState.msoTrue);
// close the ppt
fileOpen.Close();

没有人能够帮助我吗?

Answer 1

改变囚室彩色 ForeColor需要使用,而不是使用 Back。肤色可能无法按预期运作。改变使用科罗拉传输器的情况。

shape1.Table.Cell(2, 5).Shape.Fill.ForeColor.RGB = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

问题! 锡尔人的财产也可用于沙皮物体,不论它是一个单元还是另一种类型的沙皮。

Another example for the Fill property is mentioned in this thread: https://stackoverflow.com/a/26253177/20337158.
