如何从dll动态加载用户控件到asp：面板 [英] How to load a User Control dynamically from a dll into asp:panel

问题描述

我有超过3个网站。所以我想在这些应用程序中共享一些常见的用户控件。为此，我创建了一个新的Web应用程序，它具有通用的用户控件，即登录和其他一些控件。然后我使用下面的代码生成我加载到我的其他网站的ddl：



但我无法使用下面的代码将用户控件从dll加载到面板中，因为我们通过使用Control c = Page.LoadContnrol（contrlname.ascx）来完成。

Hi,
I have more than 3 websites. So I want to share some common user controls among these applications. For this purpose i have created a new web application having common user controls i.e login, and some other controls. Then i produce the ddl which i load into my other web sites using below code:

But i unable to load the user control from dll into panel using below code as we do by using Control c = Page.LoadContnrol("contrlname.ascx").

Assembly assembly = Assembly.LoadFrom(pluginPath);
Type controlType = assembly.GetType("ABCCommon.controls.LoginPanel");
object controlss = Activator.CreateInstance(controlType);      

// this section doesn't load the user control from dll into page
pnlLoginControl.Controls.Add((Control)c);

或

or

        Assembly plugin = Assembly.LoadFrom(pluginPath);

        Type[] types = plugin.GetTypes();

        foreach (Type t in types)
        {
            if (typeof(UserControl).IsAssignableFrom(t))
            {
                UserControl control = (UserControl)Activator.CreateInstance(t);

                controls.Add(control);
            }
        }

        UserControl c = (UserControl)controls[0];

// this section doesn't load the user control to page
        this.pnlLoginControl.Controls.Add(c);     

请有人帮忙吗？

谢谢！

Please can anyone help?

推荐答案

不，你是以错误的方式做的。如果您想开发可在其他网站/应用程序中重复使用的控件，请使用自定义控件。

No you are doing it in a wrong way. If you want to develop controls which can be reusable in other Web Sites/Applications then use "Custom Controls".

Have a look at below links for more information.

我的代码如下。此方法需要全名：

Assembly.GetType（字符串FullName）

my code below works. this method requires full-name:
Assembly.GetType(string FullName)

Assembly assembly = Assembly.Load("App_Web_mywsc.ascx.cdcab7d2");

// Display all the types contained in the specified assembly. 
foreach (Type oType in assembly.GetTypes())
{
    System.Diagnostics.Debug.WriteLine(oType.FullName);
}
Type controlType = assembly.GetType("ASP.mywsc_ascx");//fullname
object controlss = Activator.CreateInstance(controlType);
// this section doesn't load the user control from dll into page
myDIV.Controls.Add((Control)controlss);
