转换过程需要Office组件，请确保项目引用添加了：

Microsoft Word 12.0 Object Library

Microsoft PowerPoint 12.0 Object Library

Microsoft Excel 12.0 Object Library

 

如果发生了这个异常：无法嵌入互操作类型“Microsoft.Office.Interop.Excel.ApplicationClass”。请改用适用的接口。

把你引用的Office程序集： 属性 > 嵌入互操作类型 修改为 False 即可；

 

3. XPS 文件分拆： 参考： http://stackoverflow.com/questions/5328596/extract-a-single-page-from-an-xps-document

 

代码：

        public void Split(string originalDocument, string detinationDocument)
        {
            using (Package package = Package.Open(originalDocument, FileMode.Open, FileAccess.Read))
            {
                using (Package packageDest = Package.Open(detinationDocument))
                {
                    string inMemoryPackageName = "memorystream://miXps.xps";
                    Uri packageUri = new Uri(inMemoryPackageName);
                    PackageStore.AddPackage(packageUri, package);
                    XpsDocument xpsDocument = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);
                    XpsDocument xpsDocumentDest = new XpsDocument(packageDest, CompressionOption.Normal, detinationDocument);
                    var fixedDocumentSequence = xpsDocument.GetFixedDocumentSequence();
                    DocumentReference docReference = xpsDocument.GetFixedDocumentSequence().References.First();
                    FixedDocument doc = docReference.GetDocument(false);
                    var content = doc.Pages[0];
                    var fixedPage = content.GetPageRoot(false);
                    var writter = XpsDocument.CreateXpsDocumentWriter(xpsDocumentDest);
                    writter.Write(fixedPage);
                    xpsDocumentDest.Close();
                    xpsDocument.Close();
                }
            }
        }

注意：调用 xpsDocument.GetFixedDocumentSequence() 方法是貌似必须在UI线程才可以，否则会抛出异常；如果你在后台服务分拆XPS，请将你的线程标注为STA
