Save as Document Object尝试在 C# 中实现单词自动化时出现以下错误：

System.Runtime.InteropServices.COMException

(0x80020005)：类型不匹配。（来自 HRESULT 的异常：0x80020005 (DISP_E_TYPEMISMATCH)）

   at Microsoft.Office.Interop.Word.DocumentClass.SaveAs(Object&

FileName, Object& FileFormat, Object& LockComments, Object& Password, Object& AddToRecentFiles, Object& WritePassword, Object& ReadOnlyRecommended, Object& EmbedTrueTypeFonts, Object& SaveNativePictureFormat, Object& SaveFormsData, Object& SaveAsAOCELetter, Object& Encoding, Object& InsertLineBreaks, Object& AllowSubstitutions, Object& LineEnding, Object& AddBiDiMarks)

   at TestWordAutomation.Form1.SaveAs(String

文件名）在 D:\dotnet\WordAutomation\TestWordAutomation\TestWordAutomation\Form1.cs:line 246

   at TestWordAutomation.Form1.button4_Click(Object

发件人，EventArgs e) 在 D:\dotnet\WordAutomation\TestWordAutomation\TestWordAutomation\Form1.cs:line 557

我这样调用Save As方法：

MySaveAs("Doc1.doc");
MySaveAs("Doc2.doc");
MySaveAs("Doc3.doc");

//I have a MySaveAs function
 public void  MySaveAs(string fileName)
        {
            object FileName = null, FileFormat = null, LockComments = null, _Password = null, AddToRecentFiles = null, _WritePassword = null, _ReadOnlyRecommended = null, _EmbedTrueTypeFonts = null, SaveNativePictureFormat = null, _SaveFormsData = null, SaveAsAOCELetter = null, Encoding = null, InsertLineBreaks = null, AllowSubstitutions = null, LineEnding = null, AddBiDiMarks = null;
            FileName = (object) fileName;
            oDoc.SaveAs(ref FileName, ref FileFormat, ref LockComments, ref _Password, ref AddToRecentFiles,
                        ref _WritePassword, ref _ReadOnlyRecommended, ref _EmbedTrueTypeFonts,
                        ref SaveNativePictureFormat, ref _SaveFormsData, ref SaveAsAOCELetter, ref Encoding,
                        ref InsertLineBreaks, ref AllowSubstitutions, ref LineEnding, ref AddBiDiMarks);
        }

谁能帮我解决这个问题？

很痛苦。我记得使用 Word/Excel 互操作来实现这一点。不要轻率，但其中一个参数的类型不正确。希望以下内容有所帮助，但我做了许多此类定义。

static object s_missing = System.Reflection.Missing.Value;
static object s_true = true;
static object s_false = false;
static object s_forcesave = Word.WdSaveOptions.wdSaveChanges;

static Word._Application s_app = null;
...
return s_app.Documents.Open ( ref filename,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing,
   ref s_missing );

您不能将 null 传递给任何互操作函数调用 - 请改用 Missing.Value（如 Kenny 所建议）
