DNN模块间通信Inter Module Communication(IMC)（转自http://www.dnnsun.com）

首先,先简单介绍一下何谓IMC, IMC的全称是Inter Module Communication,它主要负责模块之间的通信.

Type:可自定义的类型标识,它主要表示当前IMC的一个认证标识,好比IMC的发送者和接收者的一个默认信号,凭借它可以把发送者和接收者牵连起来,如此接受者只监听属于它自己类型的事件.

Sender:顾名思义,这就是事件消息的发送者.

Target:事件消息的目标,也就是接收者.

Value:这是一个返回对象类型的属性,也就是IMC的重点所在,也就是你需要传递的参数,它可以是任何复杂的对象类型,比如说Dataset,Control等等,只要该事件的接收者能够解析它.

Text:可选的参数,一个简单的字符串,你可设置附加的参数信息.

消息发送：

//引用namespace

using DotNetNuke.Entities.Modules.Communications;

//继承IModuleCommunicator

public partial class List : PortalModuleBase, IActionable, IModuleCommunicator

//注册event

public event ModuleCommunicationEventHandler ModuleCommunication;

//按钮单击

protected void Button1_Click(object sender, EventArgs e)

{

    try

    {

        //To raise the event for the intermodule communication you need this code

        //Event arguments to send to listeners

        ModuleCommunicationEventArgs args = new ModuleCommunicationEventArgs();

        //Event properties (optional). Use whatever properties you need.

        //Property Text: Some text you want to send

        args.Text = "Some text";

        //Property Sender: Sender's Identification. Can be the name of the module starting the communication

        //Can be used to filter events originating from a specific module

        args.Sender = "Link";

        //Property Target: Target's Identification. Can be the name of the module to whom this event is sent

        //Can be used to filter events directed to a specific module

        args.Target = "BLOG";

        //Property Value: Any object you want to send to the listeners. You can put whatever object you need in this variable

        args.Value = "A String Object";

        //Property Type: A type specification. Can be used to filter event senders

        args.Type = this.GetType().ToString();

        //Raise the event (use the same name as defined above)

        if (ModuleCommunication != null)

        {

            ModuleCommunication(this, args);

        }

    }

    catch

    {

    }

}

监听：

//添加namespace

using DotNetNuke.Entities.Modules.Communications;

//页面继承IModuleListener

public partial class List : PortalModuleBase, IActionable,IModuleListener

//监听

public void OnModuleCommunication(object s, ModuleCommunicationEventArgs e)

{

    Label1.Text = e.Text.ToString();

}
