在PetShop4.0的ReadMe.html中有如下配置步骤:

Asynchronous Order Placement Setup Instructions

1.     Add a new private queue for Pet Shop called “PSOrders”

2.     Modifyweb.config:

a.     Change theOrderStrategyClass key to OrderAsynchronous

<add key="OrderStrategyClass" value="PetShop.BLL.OrderAsynchronous"/>

b.     Change theMachineName in the following line to your MSMQ computer name.

<add key="OrderQueuePath" value="FormatName:DIRECT=OS:MachineName\Private$\PSOrders"/>

3.     Modifyapp.config in theOrderProcessor project:

a.     Change theMachineName in the OrderQueuePath key:

<add key="OrderQueuePath" value="FormatName:DIRECT=OS:MachineName\Private$\PSOrders"/>



注意:

1、第1步,建立一个新的专用队列“PSOrders”,队列是“事务性”的。建立时,要勾选“事务性”,如图示:


2、为数据库添加登录名mspetshop,密码为pass@word1,并设置服务器角色为sysadmin。当然你也可以修改app.config中的连接字符串中的用户名和密码。





1、先安装Message Queuing Services

通过Control Panel,“Add/Remove Programs” – “Add/Remove Windows Components”步骤安装MSMQ。

MSMQ可以安装为工作组模式或域模式。如果安装程序没有找到一台运行提供目录服务的消息队列的服务器,则只可以安装为工作组模式,此计算机上的“消息队列”只支持创建专用队列和创建与其他运行“消息队列”的计算机的直接连接。


2、配置MSMQ

打开Computer Management – Message Queuing,在Private Queues下创建MSMQDemo队列


3、编写代码-简单演示MSMQ对象


注意:

添加引用:System.Messaging


代码页:

<table>
<tr>
<td style="width: 100px">
<asp:TextBox ID="txtMessage" runat="server"></asp:TextBox></td>
<td style="width: 76px">
<asp:Button ID="btnSendMessage" runat="server" OnClick="btnSendMessage_Click" Text="Send Message"
Width="132px" /></td>
</tr>
<tr>
<td style="width: 100px">
<asp:TextBox ID="txtReceiveMessage" runat="server"></asp:TextBox></td>
<td style="width: 76px">
<asp:Button ID="btnReceiveMessage" runat="server" OnClick="btnReceiveMessage_Click"
Text="Receive Message" Width="130px" /></td>
</tr>
</table>


页面布局:

// Send Message
protected void btnSendMessage_Click(object sender, System.EventArgs e)
{

// Open queue

System.Messaging.MessageQueue queue = new System.Messaging.MessageQueue(".\\Private$\\MSMQDemo");



// Create message

System.Messaging.Message message = new System.Messaging.Message();

message.Body = txtMessage.Text.Trim();

message.Formatter = new System.Messaging.XmlMessageFormatter(new Type[] { typeof(string) });



// Put message into queue

queue.Send(message);

}


// Receive Message
protected void btnReceiveMessage_Click(object sender, System.EventArgs e)
{

// Open queue

System.Messaging.MessageQueue queue = new System.Messaging.MessageQueue(".\\Private$\\MSMQDemo");



// Receive message, 同步的Receive方法阻塞当前执行线程,直到一个message可以得到

System.Messaging.Message message = queue.Receive();

message.Formatter = new System.Messaging.XmlMessageFormatter(new Type[] { typeof(string) });

txtReceiveMessage.Text = message.Body.ToString();

}
