如何在Visio中读取Shape的属性
我有以下任务。 我正在Studio 2010中的C＃上编写Visio 2010的加载项。假设我打开了一个图表。 我在这个图表中有任何形状（让我们尝试管理一个开头的形状）。 问题是如何阅读这种形状的任何属性？ 我应该使用哪种API？
基本算法：
- 扫描打开的文档以获取形状
- 如果文档中有任何形状，则返回所有形状的数组（或列表）（如果当前文档中没有形状，则返回null）
- 运行形状数组并读取每个元素的任何属性（这将有机会写/修改属性）
（代码示例将不胜感激）
我假设您通过属性引用Shape Data，它曾经在UI中称为Custom Properties，并且仍然在API中以该名称知道。
如果您不熟悉ShapeSheet，则应首先在ShapeSheet中查看具有自定义属性的形状，以查看属性的定义方式。 请参阅“ ShapeSheet发生了什么？ ”以了解如何在Visio 2010中打开Shapesheet。
以下示例程序应该可以帮助您入门。 此示例假定您已在PC上安装了Visio Primary Interop程序集，并且已在项目中包含Microsoft.Office.Interop.Visio的裁判。
namespace VisioEventsExample { using System; using Microsoft.Office.Interop.Visio; class Program { public static void Main(string[] args) { // Open up one of Visio's sample drawings. Application app = new Application(); Document doc = app.Documents.Open( @"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. */ public static void printProperties(Shapes shapes) { // Look at each shape in the collection. foreach (Shape shape in shapes) { // Use this index to look at each row in the properties // section. short iRow = (short) VisRowIndices.visRowFirst; // While there are stil rows to look at. while (shape.get_CellsSRCExists( (short) VisSectionIndices.visSectionProp, iRow, (short) VisCellIndices.visCustPropsValue, (short) 0) != 0) { // Get the label and value of the current property. string label = shape.get_CellsSRC( (short) VisSectionIndices.visSectionProp, iRow, (short) VisCellIndices.visCustPropsLabel ).get_ResultStr(VisUnitCodes.visNoCast); string value = shape.get_CellsSRC( (short) VisSectionIndices.visSectionProp, iRow, (short) VisCellIndices.visCustPropsValue ).get_ResultStr(VisUnitCodes.visNoCast); // Print the results. Console.WriteLine(string.Format( "Shape={0} Label={1} Value={2}", shape.Name, label, value)); // Move to the next row in the properties section. iRow++; } // Now look at child shapes in the collection. if (shape.Master == null && shape.Shapes.Count > 0) printProperties(shape.Shapes); } } } } 我写了一个库，使这更容易
要检索多个形状的属性：
var shapes = new[] {s1, s2}; var props = VA.CustomProperties.CustomPropertyHelper.GetCustomProperties(page, shapes);
存储在props中的返回值将是一个字典列表。 每个字典对应于指定形状的属性。 属性的名称是字典中的键。
获得第一个形状的“Foo”属性……
props[0]["Foo"]
它检索包含属性的这些方面的公式和结果的对象：
- 日历
- 格式
- 无形
- 标签
- LANGID
- 提示
- SORTKEY
- 类型
- 值
- 校验
