Question

我目前有一个合并单个单词的程序。用户选择的文档。用户有5个输入选项，允许选择文件。然后，combine按钮调用MsMerge.cs并将选定的文件合并为一个。以下是命令的示例

private void combineButton2_Click(object sender, EventArgs e)
   {
       List <string> docList = new List<string>();
       docList.Add(selectedFile1);
       docList.Add(selectedFile2);
       docList.Add(selectedFile3);
       docList.Add(selectedFile4);
       docList.Add(selectedFile5);

       if (outputFolder2 != @"")
       {
           loadingForm.Show(); // To show the loading form

       string fileDate = DateTime.Now.ToString("dd-MM-yy");
       string fileTime = DateTime.Now.ToString("HH.mm.ss");
       string outcomeFolder2 = outputFolder2;
       string outputFile2 = "Combined Files " 
                           + fileDate + " @ " + fileTime + ".docx";
       string outputFileName2 = Path.Combine(outcomeFolder2, outputFile2);

       MsWord.Merge(docList.ToArray(), outputFileName2, true);

       loadingForm.Hide(); // to hide the loading form

       // Message displaying how many files are combined.
       MessageBox.Show("A total of " + docList.Count + " documents have been merged", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
       }

我遇到的问题是当这个'合并'序列完成时，我会看到“想要保存对文档的更改” - 好像程序没有正确保存/组合所选文件。由于这个原因，我认为上面显示的'List'代码和MsWord.cs之间存在冲突，

  public class MsWord
{

    private static string defaultWordDocumentTemplate = @"Normal.dot";

    public static void Merge(string[] filesToMerge, string outputFilename, bool insertPageBreaks)
    {
        Merge(filesToMerge, outputFilename, insertPageBreaks, defaultWordDocumentTemplate);
    }

    public static void Merge(string[] filesToMerge, string outputFilename, bool insertPageBreaks, string documentTemplate)
    {
        object defaultTemplate = documentTemplate;
        object missing = System.Type.Missing;
        object pageBreak = Word.WdBreakType.wdSectionBreakNextPage;
        object outputFile = outputFilename;

        // Create a new Word application
        Word._Application wordApplication = new Word.Application();

        try
        {
            // Create a new file based on our template
            Word.Document wordDocument = wordApplication.Documents.Add(
                                          ref missing
                                        , ref missing
                                        , ref missing
                                        , ref missing);

            // Make a Word selection object.
            Word.Selection selection = wordApplication.Selection;

            // Count the number of documents to insert;
            int documentCount = filesToMerge.Length;

            // A counter that signals that we shoudn't insert a page break at the end of document.
            int breakStop = 0;

            // Loop thru each of the Word documents
            foreach (string file in filesToMerge)
            {
                breakStop++;
                // Insert the files to our template
                selection.InsertFile(
                                            file
                                        , ref missing
                                        , ref missing
                                        , ref missing
                                        , ref missing);

                //Do we want page breaks added after each documents?
                if (insertPageBreaks && breakStop != documentCount)
                {
                    selection.InsertBreak(ref pageBreak);
                }
            }

            // Save the document to it's output file.
            wordDocument.SaveAs(
                            ref outputFile
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing
                        , ref missing);

            // Clean up!
            wordDocument = null;
        }

        catch (Exception ex)
        {
            // need to add handler
        }
        finally
        {
            // Finally, Close our Word application
            wordApplication.Quit(ref missing, ref missing, ref missing);
        }
    }

}

我最初绑定了'combineButton'来合并一个string []数组而不是一个部分工作的列表，因为它允许组合5个文档，但是它需要选择所有5个用户输入。如果用户选择2/3/4文件，程序将崩溃。这导致我将我的设计从String数组更改为List。

我一直试图找到导致冲突的原因，但到目前为止还没有这样做。任何帮助将不胜感激

** 更新1

似乎越来越错误 抛出异常：'System.Runtime.InteropServices.COMException' 当程序抛出save-as弹出窗口时。

** 更新2

程序将合并文件中的5个选项。如果选择了最多5个文件，合并过程将正常工作，但如果选择了2/3/4文件，则在选择中留下空缺 - 将出现弹出错误，导致我认为空闲的浏览路径与之冲突保存过程。

最后让程序无需弹出错误/另存为错误，纯粹来自试错

private void combineButton2_Click(object sender, EventArgs e)
    {
        var docList = new List<string>();
        docList.Add(selectedFile1);
        docList.Add(selectedFile2);
        docList.Add(selectedFile3);
        docList.Add(selectedFile4);
        docList.Add(selectedFile5);
        string[] docListString = new string[docList.Count];

        if (outputFolder2 != @"")
        {
            loadingForm.Show(); // To show the form

        string fileDate = DateTime.Now.ToString("dd-MM-yy");
        string fileTime = DateTime.Now.ToString("HH.mm.ss");
        string outcomeFolder2 = outputFolder2;
        string outputFile2 = "Combined Files " + fileDate + " @ " + fileTime + ".docx";
        string outputFileName2 = Path.Combine(outcomeFolder2, outputFile2);

        MsWord.Merge(docListString, outputFileName2, true);

基本上我将按钮代码中的List docList更改为Var docList，然后手动将列表更改回字符串，而不是使用.ToArray.

我不确定为什么之前的代码不起作用，但是必须与列表和MsWord.cs发生冲突才会导致错误。感谢@AlexBell和@KirillShlenskiy的建议。

如上所述，我们发现，如果插入了5个列表项，那么2/3/4没有工作，这表明缺少文件导致了冲突。然后我添加了if语句来添加＆＃39; docs＆＃39;列表如果它们不是null，意味着它只会合并所选的内容而不是查找5个假定的文件：

  private void combineButton2_Click(object sender, EventArgs e)
    {
        var docList = new List<string>();

     // if statements to determine if the file is added
        if (selectedFile1 != null)
        {
            docList.Add(selectedFile1);
        };

        if (selectedFile2 != null)
        {
            docList.Add(selectedFile2);
        };

        if (selectedFile3 != null)
        {
            docList.Add(selectedFile3);
        };

        if (selectedFile4 != null)
        {
            docList.Add(selectedFile4);
        };

        if (selectedFile5 != null)
        {
            docList.Add(selectedFile5);
        };

        string[] docListString = docList.ToArray();

        if (outputFolder2 != @"")
        {
            loadingForm.Show(); // To show the form

        string fileDate = DateTime.Now.ToString("dd-MM-yy");
        string fileTime = DateTime.Now.ToString("HH.mm.ss");
        string outcomeFolder2 = outputFolder2;
        string outputFile2 = "Combined Files " + fileDate + " @ " + fileTime + ".docx";
        string outputFileName2 = Path.Combine(outcomeFolder2, outputFile2);

        MsWord.Merge(docListString, outputFileName2, true);

        loadingForm.Hide(); // to hide the form

        // Message displaying how many files are combined. 
        MessageBox.Show("The " + docListString.Length.ToString() + " individual Documents selected have been merged", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }

代码是abit crude但是基础知识都存在，只需要清理它并添加其他语句以确保必须选择多个文件进行合并等。

谢谢大家的建议！
