C# 如何使用asp.net查找webmethod中的服务器控件？

我已经在aspx.cs文件中编写了我的webmethod，但是当我在同一页面中调用n.Nautilus（）方法时，我无法在Nautilus（）中获取服务器端控件，在该方法控件变为NULL时，请尽快找到此问题的原因和解决方案

[WebMethod]
        public static string Execute4()
        {
            NewQuote2 n = new NewQuote2();

            JavaScriptSerializer j = new JavaScriptSerializer();
            string r = string.Empty;
            var o = Observable.Start(() =>
            {
                // Thread.Sleep(7000);
                PennStar pn = new PennStar();
                r = j.Serialize(new { res = n.Nautilus() });
            }, Scheduler.NewThread);
            o.First();
           // r = n.Nautilus();
            return r;
        }

因为您正在从

公共静态字符串Execute4（）

调用

Nautilus（）

函数，而且

Execute4（）

是

webmethod

因此

static

您无法找到任何控件，因为它们不是静态的

---

您应该尝试从

webmethod

返回结果和值，并在客户端使用这些结果执行诸如显示/隐藏div等操作。

找到了它们！真的—“尽快”？但我已经用Nautilus（）方法编写了更多的代码，这些代码不在客户端编写，（我可以更改代码并检查它），然后给我举个例子
