在C#中复制PPT形状的对象值

Question

是否可以创建一个 PPT 形状列表并让它们在从幻灯片中删除原始形状后仍保持其值？

我想在幻灯片中创建所有形状的列表，操作幻灯片，但仍然保留原始的所有信息。

List<Microsoft.Office.Interop.PowerPoint.Shape> pptShapes = new List<Microsoft.Office.Interop.PowerPoint.Shape>();
for (int jCurr = 1; jCurr <= slide.Shapes.Count; jCurr++)
                {                        
                    currShp = slide.Shapes[jCurr];
                    pptShapes.Add(currShp);
                }
//Do something else like delete a few of the shapes
if (slide.Shapes[1] != null)
{
     slide.Shapes[1].Delete();
}

//Below gives me Null since I deleted the original shape
MessageBox.Show(pptShapes[0].Type.ToString());

我想保持原来的形状，因为以后我打算copy/paste特殊到占位符等，所以我需要的不仅仅是内容。

如果您想要引用一个您希望从某种集合中删除的值，无论是 COM 还是托管，您都需要按值执行复制。在您的示例中，它看起来像这样：

List<Microsoft.Office.Interop.PowerPoint.Shape> pptShapes = new List<Microsoft.Office.Interop.PowerPoint.Shape>();
for (int jCurr = 1; jCurr <= slide.Shapes.Count; jCurr++)
                {                        
                    currShp = slide.Shapes[jCurr];
                    pptShapes.Add(currShp);
                }

string deletedString = "";

if (slide.Shapes[1] != null)
{
     string deletedString = pptShapes[0].Type.ToString();
     slide.Shapes[1].Delete();
}

MessageBox.Show(deletedString);

对于引用类型，您需要对此对象执行 DeepCopy。
