OneNote 的 OCR 识别的文本存储在 OneNote 中 XML 文件结构的 one:OCRText 元素中。例如，

<one:Page ...>
    ...
    <one:Image ...>
        ...
        <one:OCRData lang="en-US">
            <one:OCRText><![CDATA[This is some sampletext]]></one:OCRText>
        </one:OCRData>
    </one:Image>
</one:Page>

您可以使用名为 OMSPY 的程序查看此 XML（它向您显示 OneNote 页面后面的 XML） - http://blogs.msdn.com/b/johnguin/archive/2011/07/28/onenote-spy-omspy-for-onenote-2010.aspx

要提取您的文本将使用 OneNote COM 互操作（正如您所指出的）。例如，

//Instantialize OneNote
ApplicationClass onApp = new ApplicationClass();

//Get the XMl from the selected page
string xml = "";
onApp.GetPageContent("put the page id here", out xml);

//Put it into an XML document (from System.XML.Linq)
XDocument xDoc = XDocument.Parse(xml);

//OneNote's Namespace - for OneNote 2010
XNamespace one = "http://schemas.microsoft.com/office/onenote/2010/onenote";

//Get all the OCRText from the page
string[] OCRText = xDoc.Descendants(one + "OCRText").Select(x => x.Value).ToArray();

请参阅 MSDN 上的“应用程序接口”文档以获取更多信息 - http://msdn .microsoft.com/en-us/library/gg649853.aspx

Text recognized by OneNote's OCR is stored in the one:OCRText element in the XML file structure in OneNote. e.g.

<one:Page ...>
    ...
    <one:Image ...>
        ...
        <one:OCRData lang="en-US">
            <one:OCRText><![CDATA[This is some sampletext]]></one:OCRText>
        </one:OCRData>
    </one:Image>
</one:Page>

You can see this XML using a program called OMSPY (it shows you the XML behind OneNote pages) - http://blogs.msdn.com/b/johnguin/archive/2011/07/28/onenote-spy-omspy-for-onenote-2010.aspx

To extract the text you would use the OneNote COM interop (as you pointed out). e.g.

//Instantialize OneNote
ApplicationClass onApp = new ApplicationClass();

//Get the XMl from the selected page
string xml = "";
onApp.GetPageContent("put the page id here", out xml);

//Put it into an XML document (from System.XML.Linq)
XDocument xDoc = XDocument.Parse(xml);

//OneNote's Namespace - for OneNote 2010
XNamespace one = "http://schemas.microsoft.com/office/onenote/2010/onenote";

//Get all the OCRText from the page
string[] OCRText = xDoc.Descendants(one + "OCRText").Select(x => x.Value).ToArray();
