c# - 我想通过 interop.word 用 word 文档中的图像替换某些文本

Question

所以我想知道我的代码有什么问题，我试图用图像替换文本字段。具体来说，我想用 uncheck.jpg 替换“{no}”，用 check.jpg 替换“{yes}”。我知道我遗漏了一些东西，但我不知道它是什么。当我调试它时，它给出了一个异常 aDoc.InlineShapes.AddPicture("C:\Users/can.KUMSAATI/Documents/Visual Studio 2012/WebSites/WebSite4/check.jpg", ref missing, ref missing, "{yes }"); 类型不匹配。请在短时间内提供帮助。
