在tabcontrol C#中搜索标签页

Question

我的应用程序中有一个tabcontrol.我有一个列表框,其中包含错误行号和文件名以及文件路径.双击我想添加新标签页.标签页的标题应该是列表框中文件的名称.如果具有特定文件名的tabpage已经存在,那么它不应该打开新的tabpage,光标应该指向该页面.如何检索tabpages的名称.

private void lstErrorList_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            ArrayList errorType = new ArrayList();
            if (lstErrorList.Items.Count > 0)
            {
                string error = lstErrorList.SelectedItem.ToString();



                {

                    int result = error.LastIndexOf('\\');
                    string filename = error.Substring(result + 1, error.Length - (result + 1));
                    int pagecount;
                    TabPage tp = new TabPage();
                    pagecount = this.tabControl1.TabPages.Count;
                    for(int tbpagecount=0;tbpagecount<pagecount;tbpagecount++)
                    {
                        pagelist.Add(this.tabControl1.TabPages.ToString());
                    }
                    if (pagelist.Contains(filename))
                    {


                    }

                        pagecount++;
                    }

                    if (fileNamesList.Count == 0)
                        fileNamesList.Add(filename);

                        {
                            //fileNamesList.Add("");

                found = true;
            }
