                @"C:\Program Files\Microsoft Office\Office14\visio content\1033\ASTMGT_U.VST");

            // Get the first page in the sample drawing.
            Page page = doc.Pages[1];

            // Start with the collection of shapes on the page and 
            // print the properties we find,
            printProperties(page.Shapes);
        }

        /* This function will travel recursively through a collection of 
         * shapes and print the custom properties in each shape. 
         * 
         * The reason I don't simply look at the shapes in Page.Shapes is 
         * that when you use the Group command the shapes you group become 
         * child shapes of the group shape and are no longer one of the 
         * items in Page.Shapes.
         * 
         * This function will not recursive into shapes which have a Master. 
         * This means that shapes which were created by dropping from stencils 
         * will have their properties printed but properties of child shapes 
         * inside them will be ignored. I do this because such properties are 
         * not typically shown to the user and are often used to implement 
         * features of the shapes such as data graphics.
         * 
         * An alternative halting condition for the recursion which may be 
         * sensible for many drawing types would be to stop when you 
         * find a shape with custom properties.

我在评论中要求将此代码删除。所以我创造了一个新主题。

帮帮我。此代码打开文档。第一页。但！形状在表单上找不到！我总是iRow = 0.但是！形状在一张纸上！我自己提前制作了它们！可能是什么问题？

我在代码中看不到任何阻止它在Visio 2007中工作的内容。您需要使用包含第一页上具有自定义属性的形状的文件的路径。

如何在Visio中读取Shape属性
