关于winform程序中操作word的问题

Question

我在winform中调用word 2000
word2000 已经添加到工程中Interop.Word.dll，不能替换模板中的变量
我需要动态生成多个word文件，个数从ds中读取的
代码如下
：
   public ArrayList swd(string strFName, string strFind)
        {
            ArrayList textsFound = new ArrayList();  // matched texts
            object missingValue = Type.Missing;
            object missing = Type.Missing;
            Word.ApplicationClass wdApp = null;      // Word Application object            try
            {
                object fName = strFName as object;
                wdApp = new ApplicationClass();      // create a Word application object
                Word.Document wdDoc = wdApp.Documents.Open(ref fName, ref missingValue,
                    ref missingValue, ref missingValue, ref missingValue,
                    ref missingValue, ref missingValue, ref missingValue,
                    ref missingValue, ref missingValue, ref missingValue,
                    ref missingValue, ref missingValue, ref missingValue,
                    ref missingValue, ref missingValue); // open a Word object                // the Word object has paragraphs or not
                if (wdDoc.Paragraphs != null && wdDoc.Paragraphs.Count > 0)
                {
                    int count = wdDoc.Paragraphs.Count;  // the number of doc paragraphs
                    Word.Range rng;                      // Word.Range object
                    Word.Find fnd;                       // Word.Find object                    Console.WriteLine("There are {0} paragraphs in document '{1}'.", count, strFName);                    object replaceAll = Word.WdReplace.wdReplaceAll;                    
                    wdApp.Selection.Find.ClearFormatting();
                    wdApp.Selection.Find.Text = "#xjh#";                    wdApp.Selection.Find.Replacement.ClearFormatting();
                    wdApp.Selection.Find.Replacement.Text = "123";                    wdApp.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);                    string tt = wdDoc.Versions.ToString();
                    int aa = wdApp.Version.Length;
                    for (int i = 0; i < aa; i++)
                    {
                        tt = wdApp.Version[i].ToString();
                    }
                    object comment = "My first save.";
                    this.VERSIONS.Save(ref comment);                    foreach (Word.Version version in this.VERSIONS)
                    {
                        tt = version.Index.ToString();
                    }
                    //for (int i = 1; i <= count; ++i)    // search key words in every paragraphs
                    //{
                    //    rng = wdDoc.Paragraphs[i].Range;
                        
                    //    fnd = rng.Find;
                    //    fnd.ClearFormatting();
                    //    fnd.Text = strFind;                    //    if (fnd.Execute(ref missingValue, ref missingValue,
                    //        ref missingValue, ref missingValue, ref missingValue,
                    //        ref missingValue, ref missingValue, ref missingValue,
                    //        ref missingValue, ref missingValue, ref missingValue,
                    //        ref missingValue, ref missingValue, ref missingValue,
                    //        ref missingValue))
                    //    {
                    //        // if find the matched paragrahps, add it into the textsFound ArrayList.
                    //        wdDoc.Paragraphs[i].Range.Text = wdDoc.Paragraphs[i].Range.Text.Replace(strFind, "ttttt");
                    //        textsFound.Add("[" + i.ToString() + "] " + wdDoc.Paragraphs[i].Range.Text.Trim());
                    //    }
                    //}
                    //wdDoc.Save();
                    //wdDoc.Close();
                }
            }
            catch (NullReferenceException e)
            {
                Console.WriteLine(e.ToString());
                wdApp.Quit(ref missingValue, ref missingValue, ref missingValue);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
                wdApp.Quit(ref missingValue, ref missingValue, ref missingValue);
            }            // release the Word application object
            object SaveOption, OriginalFormat, RouteDocument;            SaveOption = Word.WdSaveOptions.wdSaveChanges;            OriginalFormat = Word.WdOriginalFormat.wdPromptUser;            RouteDocument = missingValue;
            wdApp.Quit(ref SaveOption,ref OriginalFormat,ref RouteDocument);            //wdApp.Quit(ref missingValue, ref missingValue, ref missingValue);            return textsFound;
        }
