此命令不可用，因為沒有打開檔案C#WPF

我正在以遞回方式從 Word 檔案生成 XPS 檔案，但我收到以下錯誤

錯誤：

此命令不可用，因為沒有打開檔案。在第 65 行的 Miscrosoft.office.interop.Word.ApplicationClass.get_ActiveDo? cument

這是：

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

我正在使用以下代碼將Word 檔案轉換為 XPS 檔案

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)
    {

    }
}

我想將所有檔案夾中的所有word檔案都轉換為XPS

在保存之前嘗試激活您的檔案

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

在您的代碼中，它看起來像：

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;
}

可能新打開的檔案尚未激活。但是該Open方法回傳檔案。因此，無需激活它或通過索引或名稱訪問它。

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

整個方法

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;
}
