从静态Web方法调用ASP.NET页面非静态方法

Question

I am in need of calling a non-static method in the active(current) asp page that the user is on by using a static WebMethod. How can I do this?

Both of these methods are within the ASP page's cs file.

    public void NormalMethod()
    {
        txtFindingNum.Text = "Ajax is da bomb";
    }

    [WebMethod]
    public static void MyWebMethod()
    {
        // This is the part I need help with...
        DoIt();
    }

Answer 1

You can't do it. It doesn't even make sense.

The instance methods of the page are about a specific instance of the page. When you're in the static web method (page method), there is no instance of the page.

If you could call the instance method from the web method, that would mean that the instance method should be a static method. Can you just add static to that method and have it still work? If not, then it depends on the particular instance of the page, and you simply can't call it when there is no instance.

Note that a page instance exists only during the HTTP request that it is serving. By the time your client-side code is calling the web service, that HTTP request is already over, and the page instance is gone.

您无法执行此操作，但是输入了txtFindingNum.Text字段，您可以使用js或jq在客户端（在回发后将更改保存在服务器中）进行更改，如下所示：

$("#<%=txtFindingNum.ClientID%>").val("Ajax is da bomb");
