C# Office开发word导出不完善问题

/// <summary>
/// 生成doc方法【带目录+加密+利用分隔符将目录单属一页】
/// </summary>
public void copyWord()
{
//1.创建新doc
Word.Application newapp = new Word.Application();
Word.Document newdoc;
object nothing = System.Reflection.Missing.Value;//用于作为函数的默认参数
newdoc = newapp.Documents.Add(ref nothing, ref nothing, ref nothing, ref nothing);//生成一个word文档
object Password = "123456";

//2.解除限制编辑
/*
if (newapp.ActiveDocument.ProtectionType == Word.WdProtectionType.wdAllowOnlyComments)
{
newapp.ActiveDocument.Unprotect(ref Password);
}
*/
//3.word可视化
newapp.Visible = true;
//4.复制旧doc
this.Select();
//5.黏贴到新doc
Object saveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
int SectionSize = this.Sections.Count;
for (int i = 1; i <= SectionSize;i++ )
{
this.Sections[i].Range.Copy();
newdoc.Sections[i].Range.PasteAndFormat(Word.WdRecoveryType.wdPasteDefault);
}
//6.初始化要操作的doc路径以及相应属性
object docFileName = newdoc.Path;
object missing = System.Reflection.Missing.Value;

//7.打开doc文件
newapp.Documents.Open(ref docFileName,
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);
newapp.Visible = true;//显示文件
object bkObj = "DictionaryContent";
if (newapp.ActiveDocument.Bookmarks.Exists("DictionaryContent"))//判断是否存在指定位置的书签
{
newapp.ActiveDocument.Bookmarks.get_Item(ref bkObj).Select();

//8.定义目录样式
newapp.Selection.Paragraphs.OutlineLevel = WdOutlineLevel.wdOutlineLevel2;
newapp.Selection.Paragraphs.OutlineLevel = WdOutlineLevel.wdOutlineLevel3;
newapp.Selection.Paragraphs.OutlineLevel = WdOutlineLevel.wdOutlineLevelBodyText;
//object x = 0;
Range myRange = newapp.ActiveDocument.Bookmarks["DictionaryContent"].Range;//关键的一步:定位目录位置
//Range myRange =this.Application.Documents[1].Sections[2].Range;
Object oUpperHeadingLevel = "1";
Object oLowerHeadingLevel = "5";
Object oTOCTableID = "content_1";//目录名称
Object oTrue = true;
Object oFalse = false;
Object oMissing = System.Reflection.Missing.Value;
//9.目录开始部分插入分页符
object oPageBreak = Word.WdBreakType.wdSectionBreakNextPage;
newapp.ActiveDocument.Bookmarks["DictionaryContent"].Range.Words.Last.InsertBreak(ref oPageBreak);//插入分页符 目录首位置
//10.目录填充到doc
newdoc.TablesOfContents.Add(myRange, ref oTrue, ref oUpperHeadingLevel,
ref oLowerHeadingLevel, ref oMissing, ref oTOCTableID, ref oTrue,
ref oTrue, ref oMissing, ref oTrue, ref oTrue, ref oTrue);

//11.目录结尾部分插入分页符
newapp.ActiveDocument.Bookmarks["DictionaryContent2"].Range.Words.Last.InsertBreak(ref oPageBreak);//插入分页符 目录末尾位置
}

//12.如果没有限制编辑为文档进行编辑限制
if (newapp.ActiveDocument.ProtectionType == Word.WdProtectionType.wdNoProtection)
{
newapp.ActiveDocument.Protect(Word.WdProtectionType.wdAllowOnlyComments, ref missing, ref Password);
}
//13.关闭并保存旧doc
this.Close(ref saveChanges, ref nothing, ref nothing);//关闭旧doc并保存
this.Application.Quit(ref saveChanges, ref nothing, ref nothing);
}
