Question

当我尝试在Windows Vista或Windows 7上运行的Word 2007中“查找并替换”时，出现以下异常。

System.AccessViolationException：试图读或写受保护记忆。这通常是一个迹象其他内存已损坏。在 Microsoft.Office.Interop.Word.Find.Execute（对象＆安培; FindText，Object＆amp; MatchCase，Object＆amp; MatchWholeWord，Object＆amp; MatchWildcards，Object＆amp; MatchSoundsLike，Object＆amp; MatchAllWordForms，Object＆amp;向前，对象和放大器;包裹，物体和格式，对象＆amp; ReplaceWith，Object＆amp;替换，对象＆amp; MatchKashida，Object＆amp; MatchDiacritics，对象和放大器; MatchAlefHamza，Object＆amp; MatchControl）

有没有解决方案？

我使用.NET3.5 C＃。

********** CODE ****************

public static Application Open(string fileName)
{
    object fileNameAsObject = (object)fileName;
    Application wordApplication;            
    wordApplication = new Application();
    object readnly = false;
    object missing = System.Reflection.Missing.Value;
    wordApplication.Documents.Open(
        ref fileNameAsObject, ref missing, ref readnly,

        ref missing,ref missing, ref missing, ref missing, 
        ref missing,ref missing, ref missing, ref missing, 
        ref missing
    );

    return wordApplication;             
}

private static void ReplaceObject(
    ref Application wordApplication, 
    object ObjectTobeReplaced, object NewObject)
{
    // ++++++++Find Replace options Starts++++++

object findtext = ObjectTobeReplaced;
    object findreplacement = NewObject;
    object findforward = true;
    object findformat = false;
    object findwrap = WdFindWrap.wdFindContinue;
    object findmatchcase = false;
    object findmatchwholeword = false;
    object findmatchwildcards = false;
    object findmatchsoundslike = false;
    object findmatchallwordforms = false;
    object replace = 2; //find = 1; replace = 2
    object nevim = false;
    Range range = wordApplication.ActiveDocument.Content;
    range.Find.Execute(
        ref findtext, ref findmatchcase, ref findmatchwholeword, 
        ref findmatchwildcards,ref findmatchsoundslike,

Answer 1

重新安装Office后修复了问题：）...但仍然不知道导致问题的原因

Answer 2

如果没有显示任何代码，这几乎无法回答。

一个（狂野的）猜测是，当你使用未初始化的Word进行交互时，你会提供一些类/结构，然后Word会尝试访问未初始化的内存。
