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);

RT 点击发送后报错：
未处理 System.ArgumentOutOfRangeException

[解决办法]
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();

}
