我如何获取C＃CefSharp的文本，是否需要检查条件

Question

我有以下C＃

var checktransaction = frame.EvaluateScriptAsync("document.querySelector('div[id=helpdiv]').innerText;");

我想通过其他条件检查交易

我尝试过：

if (checktransaction.ToString()  == "Withdraw Successful.")
{
    status.Invoke((MethodInvoker)delegate {
        status.Text = "The transaction is successful.";
    });
}
return value System.Threading.Tasks.Taks[CefSharp.JavascriptRespons]

我的英语不太好

更新：是的，到目前为止，我使用的是我的代码：

string script = string.Format("document.querySelector('div[id=helpdiv]').innerText;");
                frame.EvaluateScriptAsync(script).ContinueWith(x =>
                {
                    var response = x.Result;

                    if (response.Success && response.Result != null)
                    {


                        string s1 = (string)response.Result;



                        if(s1 == "Withdraw Successful.")
                        {
                            withdrowSuccessful = 10;
                            withdrowScucess = true;
                            status.Invoke((MethodInvoker)delegate
                            {
                                status.Text = "Withdraw Successful.";

                            });
                        }
                    }
                });
