以编程方式更改Content Editor Web部件文本

大家好，
我试图以编程方式更改shareopoint中内容编辑器Web部件的内容时遇到了一些问题.实际上，我已经在设计者的页面上创建了一个内容编辑器Web部件，当我使用下面的给定代码更改内容时.找不到错误，它显示内容已更改，但是当我尝试从内容编辑器Web部件中获取该内容时，它显示的是更改前的先前文本.因此，我的内容编辑器Web部件的内容没有更改，也没有发现错误...这是我的代码.

Hi Guys,
I am facing some problem while i am trying to change the content of content editor web part in shareopoint programmatically. Actually i have created a content editor web part on a page from designer and when i am using the below given code to change the content. No eror found and it shows that content have been changed but when i try to fetch that content from content editor web part, it is showing the previous text before getting change. So my Content editor web part content is not changing and no error found as well... Here is my code.

using (SPSite site = new SPSite(url + webPartPage))
             using (SPWeb web = site.OpenWeb())
             {
                 //give relative path of the webpartpage

                 SPFile file = web.GetFile(url +webPartPage);
                  try
                     {

                         SPLimitedWebPartManager wm = web.GetLimitedWebPartManager(webPartPage, System.Web.UI.WebControls.WebParts.PersonalizationScope.User);

                 if (file.CheckOutStatus == SPFile.SPCheckOutStatus.None)
                 {
                     file.CheckOut();
                 }


                 foreach (System.Web.UI.WebControls.WebParts.WebPart wp1 in wm.WebParts)
                 {
                     objUT.EnableSecurity(web, web.Site.WebApplication, site);
                     Microsoft.SharePoint.Administration.SPWebApplication webApp = web.Site.WebApplication;
                     webApp.FormDigestSettings.Enabled = false;

                         wp1.AllowEdit = true;

                         ContentEditorWebPart contentEditor = wp1 as ContentEditorWebPart;


                         if (contentEditor != null && wp1.ID == ddlWebpart.SelectedValue.ToString())
                         {
                             string strOldContent = contentEditor.Content.InnerText;
                             //Session["WPID"] = wp1.ID;
                             //Session["Content"] = strOldContent;
                            // wm.DeleteWebPart(contentEditor);
                             XmlDocument xmlDoc = new XmlDocument();
                             XmlElement xmlElement = xmlDoc.CreateElement("HtmlContent");
                             xmlElement.InnerText = contentEditor.Content.InnerText.Replace(strOldContent,Editor.Text); //Editor.Text;
                             contentEditor.Content = xmlElement;

                             wm.SaveChanges(contentEditor);

                             Editor.Text = contentEditor.Content.InnerText;

                             string[] ParamNames = { "PageURL", "WebpartID", "WebpartOrgContent", "WebpartChaContent", "IsApproved", "CreatedOn", "CreatedBy", "ModifiedOn", "ModifiedBy" };
                             string[] ParamValues = { url + webPartPage, wp1.ID, strOldContent, Editor.Text, "Pending", System.DateTime.Now.ToString(), System.Environment.UserName, System.DateTime.Now.ToString(), System.Environment.UserName };
                             objUT.insertWPContentUpdationHistory(url+webPartPage, ParamNames, ParamValues, strListContentUpdationHistory, strListPagesContentUpdationHistory);
                         }
                         wp1.AllowEdit = false;
                         webApp.FormDigestSettings.Enabled = true;
                       //  wm.Dispose();

                     }
                      file.Update();

                 file.CheckIn("ss");
                // Editor.Text = "";
                 }
                  catch (Exception ex1)
                  {
