OpenOffice with .NET：如何遍历所有段落并阅读文本

如何遍历OpenOffice Writer文档中的所有段落并输出文本。 我有Java示例，但不知道如何将代码转换为C＃。 Java示例可以在这里找到： http ： //wiki.services.openoffice.org/wiki/API/Samples/Java/Writer/TextDocumentStructure

我的C＃代码：

InitOpenOfficeEnvironment(); XMultiServiceFactory multiServiceFactory = connect(); XComponentLoader componentLoader = XComponentLoader)multiServiceFactory.createInstance("com.sun.star.frame.Desktop"); //set the property PropertyValue[] propertyValue = new PropertyValue[1]; PropertyValue aProperty = new PropertyValue(); aProperty.Name = "Hidden"; aProperty.Value = new uno.Any(false); propertyValue[0] = aProperty; XComponent xComponent = componentLoader.loadComponentFromURL( @"file:///C:/code/test3.doc", "_blank", 0, propertyValue); XEnumerationAccess xEnumerationAccess = (XEnumerationAccess)xComponent; XEnumeration xParagraphEnumeration = xEnumerationAccess.createEnumeration(); while ( xParagraphEnumeration.hasMoreElements() ) { // ??? // The problem is here nextElement() returns uno.Any but // I some how should get XTextContent???? uno.Any textElement = xParagraphEnumeration.nextElement(); // create another enumeration to get all text portions of //the paragraph XEnumeration xParaEnumerationAccess = textElement.createEnumeration(); //step 3 Through the Text portions Enumeration, //get interface to each individual text portion } xComponent.dispose(); xComponent = null;

好的，我找到了答案，我希望能为那些遇到同样问题的人节省一些时间……

令人惊讶的是，更多人似乎并不了解ODF工具包 。 我没有太多使用它，只是通过源头查看。 您可能遇到的一个问题是您无法保存到流，只能保存到文件。 虽然解决方法是保存到临时文件，然后流式传输。
