TextBox txtContent = new TextBox();

SPList announcementList = mySite.Lists["Announcements"];
SPListItem getAnnouncement = announcementList.Items[0];
txtContent.Text = getAnnouncement["Body"].ToString();

我希望输出为

string txt = bodyField.GetFieldValueAsText(getAnnouncement["Body"]);
string html = bodyField.GetFieldValueAsHtml(getAnnouncement["Body"]);
