如何解决如何在Visio中读取Shape的属性
| 我有以下任务。我正在Studio 2010中使用C＃编写Visio 2010加载项。 假设我打开了一个图表。在此图中，我有一个任意形状（让我们从一开始就尝试管理一个形状）。问题是如何读取此形状的任何属性？我应该使用哪个API？ 基本算法： 扫描打开的文档中的形状 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） 在shapes数组上运行并读取每个元素的任何属性（有机会对属性进行编写/修改将非常有帮助） （代码示例将不胜感激）解决方法
我假设通过属性来引用形状数据，该形状数据过去在UI中称为“自定义属性”，但在API中仍通过该名称知道。
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，以了解如何定义属性。请参阅“ ShapeSheet发生了什么？”，以了解如何在Visio 2010中打开Shapesheet。
以下示例程序将帮助您入门。本示例假定您在PC上安装了Visio主Interop程序集，并且在项目中包含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,(short) VisCellIndices.visCustPropsLabel
).get_ResultStr(VisUnitCodes.visNoCast);
string value = shape.get_CellsSRC(
(short) VisSectionIndices.visSectionProp,(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);
