窗体Text修改方式

方法有二

1.直接修改TEXT：

this.Text = "csg - " + FullFileName;

2.通过调用DLL文件修改：

 #region 方法二
            docManagerData.NewDocName = FullFileName;
            docManager = new DocManager(docManagerData);
            docManager.RegisterFileType("csg", "csgfile", "DrawTools File");//文件关联

            // Subscribe to DocManager events.
            docManager.SaveEvent += docManager_SaveEvent;
            docManager.LoadEvent += docManager_LoadEvent;

            // Make "inline subscription" using anonymous methods.
            docManager.OpenEvent += delegate(object sender, OpenFileEventArgs e)
            {
                // Update MRU List
                if (e.Succeeded)
                    mruManager.Add(e.FileName);
                else
                    mruManager.Remove(e.FileName);
            };

            docManager.DocChangedEvent += delegate
            {
                drawArea.Refresh();
                drawArea.ClearHistory();
            };

            docManager.ClearEvent += delegate
            {
                bool haveObjects = false;

                if (drawArea.Graphicslist.Count > 1)
                {
                    haveObjects = true;

                }

                if (haveObjects)
                {
                    drawArea.Graphicslist.Clear();
                    drawArea.ClearHistory();
                    drawArea.Refresh();
                }
            };
            docManager.NewDocument();
            #endregion
