嗯... ImageFormat.pdf不是ImageFormat类的成员，所以你在哪里获得从哪？该代码甚至不会编译，更不用说工作了。你不能只是键入你想要作为类成员的任何旧扩展并期望它工作。
图像和位图类不知道如何以PDF格式保存图像格式。您必须使用第三方库（如PdfSharp）创建PDF文档并将图像插入到文档中。
Ummm... ImageFormat.pdf is not a member of the ImageFormat class so where did you get that from? That code won't even compile let alone work. You cannot just type any old extension you want as a class member and expect it to work.
The Image and Bitmap classes have no idea how to save an image in PDF format. You have to create a PDF document and insert your image into the document using a 3rd party library, like PdfSharp.
