消息队列 长度不能小于 0。 参数名: length
C# code

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

            System.Messaging.Message message = new System.Messaging.Message();
            message.Body = textBox1.Text.Trim();
            message.Formatter = new System.Messaging.XmlMessageFormatter(new Type[] { typeof(string) });
            queue.Send(message);

未处理 System.ArgumentOutOfRangeException
  Message=长度不能小于 0。
  参数名: length

------解决方案--------------------
用下面这段试验一下。

// Send Message

private 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

private 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();

}
