如何在c#中读取Visio文档内容
本文关键字:Visio 文档 读取 | 更新日期: 2023-09-27 18:11:26
我的DLL库代码如下:
using System;
using IVisio=Microsoft.Office.Interop.Visio;
namespace Emix
{
public class Visio
{
protected String path;
public Visio(String path)
{
this.path = path;
}
public void open()
{
try
{
IVisio.Document doc = new IVisio.Application().Documents.Add(this.path);
Console.WriteLine("Number of pages: " + doc.Pages.Count);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
但是,这段代码打开Visio编辑器,然后显示文档中的页数。
是否可以在不打开Visio的情况下读取该文件内容?
这是如何在visio中读取形状属性的程序....
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 sense 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);
}
}
}
}
上面的例子假设你已经在你的PC上安装了Visio Primary Interop Assembly,并且在你的项目中包含了一个Microsoft.Office.Interop.Visio的裁判。
我希望这对你有帮助....
如果你使应用程序不可见,你将不会看到新的Visio实例打开(仍然会有一个Visio实例运行,只是不是可见的)
Application application = new Application();
application.Visible = false;
Document doc = application.Documents.Add(this.path);
Console.WriteLine("Number of pages: " + doc.Pages.Count);
看一下如何使用c#在Visio上获取形状数据信息。它包含一些关于您的场景的有用信息
这篇文章还解释了如何获取所有的形状以及如何将所有的形状连接在一起
正如另一个答案指出的那样,您可以使用应用程序。
另一种选择是直接读取Visio的VDX文件格式来检索页面数、自定义属性等。这避免了必须启动Visio才能从文件中读取信息。但是这个解决方案确实要求您将VDX的文件变成XML模式。
