C#生成word查找替换出现的经典问题

       想用C#动态更换WORD文档中的一些文本，如果用了一些不当的方法，很可能会出现有某PC上能正常替换在另外一台PC则不能替换的问题。
      比如下面注释掉的代码就会出现问题。

        ///
        /// personalName()用来调用替换名字的
        ///
        /// 要被替换的名字
        /// 要替换的名字
        public void replaceName(string oldName,string newName)
        {
            //Word.Find findObject = word.Selection.Find;
            //findObject.ClearFormatting();
            //findObject.Text = oldName;
            //findObject.Replacement.ClearFormatting();
            //findObject.Replacement.Font.Name = "黑体";
            //findObject.Replacement.Text = newName;
            //object replaceAll = Word.WdReplace.wdReplaceAll;
            //findObject.Execute(ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            //    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            //    ref replaceAll, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
            //object replaceAll = Word.WdReplace.wdReplaceAll;
            //object missing = Type.Missing;
            ////首先清除任何现有的格式设置选项，然后设置搜索字符串 strOldText。
            //this.word.Selection.Find.ClearFormatting();
            //word.Selection.Find.Text = oldName;
            //word.Selection.Find.Replacement.ClearFormatting();
            //word.Selection.Find.Replacement.Text = newName;
            //word.Selection.Find.Replacement.Font.Name = "黑体";
            //word.Selection.Find.Execute(
            //    ref missing, ref missing, ref missing, ref missing, ref missing,
            //    ref missing, ref missing, ref missing, ref missing, ref missing,
            //    ref replaceAll, ref missing, ref missing, ref missing, ref missing);
            object myFind = word.Selection.Find;
            object findText = oldName;
            object replaceText = newName;
            object replaceAll = Word.WdReplace.wdReplaceAll;
            object oMissing = System.Reflection.Missing.Value;
            try
            {
                object[] Parameters;
                Parameters = new object[15];
                Parameters[0] = findText;
                Parameters[1] = oMissing;
                Parameters[2] = oMissing;
                Parameters[3] = oMissing;
                Parameters[4] = oMissing;
                Parameters[5] = oMissing;
                Parameters[6] = oMissing;
                Parameters[7] = oMissing;
                Parameters[8] = oMissing;
                Parameters[9] = replaceText;
                Parameters[10] = replaceAll;
                Parameters[11] = oMissing;
                Parameters[12] = oMissing;
                Parameters[13] = oMissing;
                Parameters[14] = oMissing;
                //word.Selection.Find.Replacement.Font.Name = "黑体";
                myFind.GetType().InvokeMember("Execute", BindingFlags.InvokeMethod, null, myFind, Parameters);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
            //object replaceAll = Word.WdReplace.wdReplaceAll;
            //Word.Document document = word.ActiveDocument;
            //Word.Range rng = document.Content;
            //rng.Find.ClearFormatting();
            //rng.Find.Text = oldName;
            //rng.Find.Replacement.ClearFormatting();
            //rng.Find.Replacement.Text = newName;
            //rng.Find.Replacement.Font.Name = "黑体";
            //rng.Find.Execute(
            //    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            //    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            //    ref replaceAll, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
            //    object missing = Type.Missing;
            //    object replaceAll = Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;
            //    Microsoft.Office.Interop.Word.Find findObject = myWord.ActiveDocument.Content.Find;
            //    findObject.ClearFormatting();
            //    findObject.Text = strOldText;
            //    Microsoft.Office.Interop.Word.Replacement replacementObject = findObject.Replacement;
            //    replacementObject.ClearFormatting();
            //    findObject.Replacement.Text = strNewText;
            //    findObject.Replacement.Font.Name = "黑体";
            //    findObject.Execute(ref missing, ref missing, ref missing,
            //        ref missing, ref missing, ref missing, ref missing,
            //        ref missing, ref missing, ref missing, ref replaceAll,
            //        ref missing, ref missing, ref missing, ref missing);
        }

    以上四种方法，但是对我初学者看来都差不多，但是被注释的三种方法，在有些电脑上运行会提示错误：
************** 异常文本 **************
System.Runtime.InteropServices.SEHException: 外部组件发生异常。
   在 Microsoft.Office.Interop.Word.Find.set_Text(String prop)
   在 wordTest.Form2.replaceName(String oldName, String newName)
***************************************

    从网上搜集好多资料说把参数写开，就是上面没被注释的方法，就不再报“外部组件发生异常”的事情了。
