将图片从word保存到文件夹C#

Question

所以我想出了如何使用这个link用word中的文字替换图片

但现在我需要将图片从 word 导出到文件夹。而且我猜每当我找到一个对象的图片（type s=Microsoft.Office.Interop.Word.WdInlineShapeType.wdInlineShapePicture）我应该用它做点什么......但我找不到选项：s。 saveAsPicture(@"C:\pic.jpg");

您的问题可能与以下内容重复：extract image from word file

但是，基于my previous answer 对您关于如何以编程方式将外部图像与 Word 中的内联形状进行比较的问题（请参阅Compare picture in Word file and in a folder?） - 您可以进行一些简单的调整并使用几乎完全相同的示例代码将每个内联形状导出到一个文件夹，而不是将这些形状与另一个图像进行比较。

为了说明我已经为你做了必要的调整，并提供了下面的源代码。同样，该应用程序是基于 .NET 4.5、Microsoft Office 对象库版本 15.0 和 Microsoft Word 对象库版本 15.0 的 C# 控制台应用程序。

和以前一样，我在源代码中包含了引用，这样您就可以看到我的解决方案基于哪些来源（并且这些来源得到了他们应得的荣誉；））
