命名空间： HslCommunication.Core.IMessage
程序集： HslCommunication (在 HslCommunication.dll 中) 版本：12.1.2.0 (12.1.2.0)
语法INetMessage 类型公开以下成员。
属性| 名称 | 说明 | |
|---|---|---|
 | ContentBytes |
消息内容字节 Message content byte |
| HeadBytes |
消息头字节 Message header byte |
| ProtocolHeadBytesLength |
消息头的指令长度，第一次接受数据的长度 Instruction length of the message header, the length of the first received data |
| SendBytes |
发送的字节信息 Byte information sent |
方法| 名称 | 说明 | |
|---|---|---|
 | CheckHeadBytesLegal |
检查头子节的合法性 Check the legitimacy of the head subsection |
| CheckMessageMatch |
检查发送的接收的报文是否是匹配的，如果匹配，则返回 1, 如果不匹配且直接返回错误，则返回 0，如果不匹配继续接收，直到匹配或是超时，则返回 -1 If the packet is matched, 1 is returned. If the packet is not matched and an error is returned, 0 is returned. If the packet is not matched, -1 is returned until the packet is matched or times out |
| CheckReceiveDataComplete |
当消息头报文的长度定义为-1的时候，则使用动态的长度信息，可以使用本方法来判断一个消息是否处于完整的状态。 If the length of the message header is defined as -1, this method can be used to determine whether a message is in the complete state by using dynamic length information. |
| GetContentLengthByHeadBytes |
从当前的头子节文件中提取出接下来需要接收的数据长度 Extract the length of the data to be received from the current header file |
| GetHeadBytesIdentity |
获取头子节里的消息标识 Get the message ID in the header subsection |
| PependedUselesByteLength |
在接收头报文的时候，返回前置无效的报文头字节长度，默认为0，不处理 When receiving a header message, return the header byte length of the invalid header, the default is 0, and no processing is performed. |
