此命令不可用，因为没有打开文档 C# WPF

Question

我正在以递归方式从 Word 文档生成 XPS 文档，但出现以下错误

错误：

此命令不可用，因为没有打开文档。在第 65 行的 Miscrosoft.office.interop.Word.ApplicationClass.get_ActiveDo‌​cument

这是：

wordApp.ActiveDocument.SaveAs2(xpsFile, FileFormat: Word.WdSaveFormat.wdFormatXPS);

我正在使用以下代码将 Word 文件转换为 XPS 文件

public static string convertWordToXps(string path, string wordDocName)
{
    Word.Application wordApp = new Word.Application();
    wordApp.Documents.Open(string.Concat(path, "\\", wordDocName), ConfirmConversions: false, ReadOnly: false);

    string xpsFile = string.Concat(path, "\\", Path.GetFileNameWithoutExtension(wordDocName), ".xps");

    try
    {
        //wordApp.ActiveDocument.ExportAsFixedFormat(xpsFileName, WdExportFormat.wdExportFormatXPS, false, WdExportOptimizeFor.wdExportOptimizeForOnScreen, WdExportRange.wdExportAllDocument, 1, 1, WdExportItem.wdExportDocumentContent, false, true, WdExportCreateBookmarks.wdExportCreateNoBookmarks, false, true, false, nullObject);
        wordApp.ActiveDocument.SaveAs2(xpsFile, FileFormat: Word.WdSaveFormat.wdFormatXPS);
        return xpsFile;
    }
    catch (Exception e)
    {
        MessageBox.Show(e.getDetailedErrorMessage());
    }
    finally
    {
        wordApp.Quit(SaveChanges: false, OriginalFormat: Type.Missing, RouteDocument: Type.Missing);
    }
    return null;
}

搜索功能

private void SearchDocuments(string directoryPath)
{
    try
    {
        foreach (string fullName in Directory.GetFiles(directoryPath, "*.odt"))
        {
            InstructionsViewModel.convertWordToXps(System.IO.Path.GetDirectoryName(fullName), System.IO.Path.GetFileNameWithoutExtension(fullName));
        }
        foreach (string nestedDirectory in Directory.GetDirectories(directoryPath))
        {
            SearchDocuments(nestedDirectory);
        }
    }
    catch (System.Exception error)
    {

    }
}

我想将所有文件夹中的所有word文件都转换为XPS

在保存之前尝试激活您的文档

wordApplication= new Microsoft.Office.Interop.Word.Application();
var document= wordApplication.Documents.Open(@"path/to/document.docx");  
document.Activate();
// and now save.

在您的代码中，它看起来像：

public static string convertWordToXps(string path, string wordDocName)
{
    Word.Application wordApp = new Word.Application();
    var document= wordApp.Documents.Open(string.Concat(path, "\\", wordDocName), ConfirmConversions: false, ReadOnly: false);
    document.Activate();
    string xpsFile = string.Concat(path, "\\", Path.GetFileNameWithoutExtension(wordDocName), ".xps");

    try
    {
        //wordApp.ActiveDocument.ExportAsFixedFormat(xpsFileName, WdExportFormat.wdExportFormatXPS, false, WdExportOptimizeFor.wdExportOptimizeForOnScreen, WdExportRange.wdExportAllDocument, 1, 1, WdExportItem.wdExportDocumentContent, false, true, WdExportCreateBookmarks.wdExportCreateNoBookmarks, false, true, false, nullObject);
        wordApp.ActiveDocument.SaveAs2(xpsFile, FileFormat: Word.WdSaveFormat.wdFormatXPS);
        return xpsFile;
    }
    catch (Exception e)
    {
        MessageBox.Show(e.getDetailedErrorMessage());
    }
    finally
    {
        wordApp.Quit(SaveChanges: false, OriginalFormat: Type.Missing, RouteDocument: Type.Missing);
    }
    return null;
}

可能新打开的文档尚未激活。但是Open 方法会返回文档。因此，无需激活它或通过索引或名称访问它。

Word.Document doc = wordApp.Documents.Open(...);
doc.SaveAs2(...);

整个方法

public static string convertWordToXps(string path, string wordDocName)
{
    var wordApp = new Word.Application();
    Word.Document doc = wordApp.Documents.Open(Path.Combine(path, wordDocName), ConfirmConversions: false, ReadOnly: false);

    string xpsFile = Path.Combine(path, Path.ChangeExtension(wordDocName, ".xps"));

    try {
        doc.SaveAs2(xpsFile, FileFormat: Word.WdSaveFormat.wdFormatXPS);
        return xpsFile;
    } catch (Exception e) {
        MessageBox.Show(e.getDetailedErrorMessage());
    } finally {
        wordApp.Quit(SaveChanges: false, OriginalFormat: Type.Missing, RouteDocument: Type.Missing);
    }
    return null;
}
