exception - System.AccessViolationException : Attempted to read or write protected memory

Question

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

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at Microsoft.Office.Interop.Word.Find.Execute(Object& FindText, Object& MatchCase, Object& MatchWholeWord, Object& MatchWildcards, Object& MatchSoundsLike, Object& MatchAllWordForms, Object& Forward, Object& Wrap, Object& Format, Object& ReplaceWith, Object& Replace, Object& MatchKashida, Object& MatchDiacritics, Object& MatchAlefHamza, Object& MatchControl)

有什么解决办法吗？

我正在使用 .NET3.5 C#。

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 missing
    );

    return wordApplication;             
}

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

    object replace = 2; //find = 1; replace = 2
    object nevim = false;
    Range range = wordApplication.ActiveDocument.Content;
    range.Find.Execute(
        ref findtext, ref findmatchcase, ref findmatchwholeword,

重新安装 Office 后问题已修复 :)...但仍然不知道是什么导致了问题
