OpenOffice的使用.NET：如何遍历所有throught段落和文本阅读 [英] OpenOffice with .NET: how to iterate throught all paragraphs and read text

问题描述

如何通过OpenOffice的Writer文档和文本输出的所有段落重复。
我有Java的例子，但不知道如何代码转换为C＃。
Java的例子可以在这里找到：的http：// wiki.services.openoffice.org/wiki/API/Samples/Java/Writer/TextDocumentStructure

我的C＃代码：

  InitOpenOfficeEnvironment（）; 
 XMultiServiceFactory multiServiceFactory =连接（）; 
 XComponentLoader componentLoader = 
 XComponentLoader）multiServiceFactory.createInstance（com.sun.star.frame.Desktop）; 
 
 //设置属性
为PropertyValue [] =的PropertyValue新为PropertyValue [1]; 
为PropertyValue aProperty =新为PropertyValue（）; 
 aProperty.Name =隐藏; 
 aProperty.Value =新uno.Any（假）; 
的PropertyValue [0] = aProperty; 
 
 XComponent xComponent = 
 componentLoader.loadComponentFromURL（
 @的文件：/// C：/code/test3.doc，
_blank，0，为PropertyValue）; 
 
 XEnumerationAccess xEnumerationAccess =（XEnumerationAccess）xComponent; 
 XEnumeration xParagraphEnumeration = xEnumerationAccess.createEnumeration（）; 
 
，而（xParagraphEnumeration.hasMoreElements（））
 {
 //？ 
 //问题是在这里nextElement（）返回uno.Any但是
 //我一些应该怎么弄XTextContent ???? 
 uno.Any的TextElement = xParagraphEnumeration.nextElement（）; 
 
 //创建另一个枚举得到
 //段落
 XEnumeration xParaEnumerationAccess = textElement.createEnumeration的所有文字部分（）; 
 
 //第3步通过文字部分枚举，
 //获取接口，每个文本部分
} 
 
 xComponent.dispose（）; 
 xComponent = NULL; 
  

解决方案

OK，我找到了答案，我希望它会节省时间对于那些谁面临着同样的问题...

How to iterate through all paragraphs in OpenOffice Writer document and output text. I have Java examples, but don't know how to convert code to C#. Java example could be found here: http://wiki.services.openoffice.org/wiki/API/Samples/Java/Writer/TextDocumentStructure

My C# code:

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;
