C# word标签替换问题

Question

各位大侠好：
          我遇到word中标签替换的问题，在word文档中我在两个地方用到同一个标签名，添加后，我c#生成word文档替换标签内容时只能将第一个标签替换过来，第二个并没有成功替换，这个问题怎么解决？

Answer 1

 Word.Document doc = null;// new Word.Document();
            //Document doc = new Document();
            object Obj_FileName = newfilePath;
            object Visible = false;
            object ReadOnly = false;
            object missing = System.Reflection.Missing.Value;
            Book book = new Book();
            try
            {
                //打开文件
                doc = app.Documents.Open(ref Obj_FileName, ref missing, ref ReadOnly, ref missing,
                    ref missing, ref missing, ref missing, ref missing,
                    ref missing, ref missing, ref missing, ref Visible,
                    ref missing, ref missing, ref missing,
                    ref missing);
                doc.Activate();                 try
                {
                    object BookMarkName = "name";
                    object what = Word.WdGoToItem.wdGoToBook;
                    if (app.ActiveDocument.Books.Exists("name") == true)
                    {
                        //WordApp.ActiveDocument.Books.get_Item(ref BookMarkName).Select();
                        try
                        {
                            doc.ActiveWindow.Selection.GoTo(ref what, ref missing, ref missing, ref BookMarkName);
                            string name = wd.Ht_HT.First(h => h.ID == Convert.ToInt64(buildID)).name.ToString();
                            doc.ActiveWindow.Selection.TypeText(name.ToString());
                        }
                        catch
                        {
                            catchstring += "该名称替换失败!";
                        }
                    }
catch{}代码就是这样子来写的了

Answer 2

这句是什么?
string name = wd.Ht_HT.First(h => h.ID == Convert.ToInt64(buildID)).name.ToString(); 
try: doc.ActiveWindow.Selection.Find.Execute(

Answer 3

string name = wd.Ht_HT.First(h => h.ID == Convert.ToInt64(buildID)).name.ToString(); 
这句是linq语句，
我是用书签替换的呀find.Execute()如何用呢？

Answer 4

       object Find = "123";
                            object NewString = "ZZZZZZZ";
                          //  doc.ActiveWindow.Selection.
                            object Replace = Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;                            doc.ActiveWindow.Selection.Find.Execute(ref Find, ref missing, ref missing, ref missing,
                                    ref missing, ref missing, ref missing, ref missing, ref missing, ref NewString, ref Replace, ref missing, ref missing, ref missing, ref missing);                     

Answer 5

doc.ActiveWindow.Selection.Find.Execute(ref BookMarkName, ref missing, ref missing, ref missing,
     ref missing, ref missing, ref missing, ref missing, ref missing, ref BookValue, ref Replace, ref missing, ref missing, ref missing, ref missing); 
为什么我按照这个来替换根本替换不了呢？
