Message in Chinese (Traditional) (中文（繁體）)
這項作業的 WebSocket 處於無效狀態。'<var>X</var>' 方法先前已經在這個執行個體上呼叫過。請改用 '<var>Y</var>'，以便接收資料並關閉輸出通道。
Unlocalized message
The WebSocket is in an invalid state for this operation. The '<var>X</var>' method has already been called before on this instance. Use '<var>Y</var>' instead to keep being able to receive data but close the output channel.
