使用 openxml C# 生成的损坏的 powerpoint pptx

Question

I am getting the following error while opening the powerpoint file, generated using open xml. I compared the xml of repaired file and corrupted file, it seems to be the same. Can you please help

Thanks in advance.

Edit:

I used the sample code from here . If you run this code, it works fine. However, if we change this part:

   bodyShape.TextBody = new TextBody(new Drawing.BodyProperties(),
                        new Drawing.ListStyle(),
                        new Drawing.Paragraph(new Drawing.Run(new Drawing.Text() { Text = text }));

It creates the corrupt file.

                string _DescripcionSuperior = "Hello World";

                bodyShape.TextBody = new P.TextBody(new Drawing.BodyProperties(),
                             new Drawing.ListStyle(),
                             new Drawing.Paragraph(new Drawing.Run(
                                 new Drawing.RunProperties() { Language = "es-MX", FontSize = 1000, Dirty = false, Bold = false },
                                 new Drawing.Text(_DescripcionSuperior)
                                 )));
