语法SiemensPPIServerMessage 类型公开以下成员。
构造函数| 名称 | 说明 | |
|---|---|---|
 | SiemensPPIServerMessage | 初始化 SiemensPPIServerMessage 类的一个新实例 |
属性| 名称 | 说明 | |
|---|---|---|
 | ContentBytes |
消息内容字节 (继承自 NetMessageBase。)Message content byte |
| HeadBytes |
消息头字节 (继承自 NetMessageBase。)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 (继承自 NetMessageBase。)Byte information sent |
方法| 名称 | 说明 | |
|---|---|---|
| CheckHeadBytesLegal |
检查头子节的合法性 (继承自 NetMessageBase。)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 (继承自 NetMessageBase。)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。 (继承自 NetMessageBase。)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. |
| Equals | Determines whether the specified object is equal to the current object. (继承自 Object。) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (继承自 Object。) |
| 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 |
| GetHashCode | Serves as the default hash function. (继承自 Object。) |
| GetHeadBytesIdentity |
获取头子节里的消息标识 (继承自 NetMessageBase。)Get the message ID in the header subsection |
| GetType | Gets the Type of the current instance. (继承自 Object。) |
| MemberwiseClone | Creates a shallow copy of the current Object. (继承自 Object。) |
| 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 (继承自 NetMessageBase。)When receiving a header message, return the header byte length of the invalid header, the default is 0, and no processing is performed. |
| ToString | Returns a string that represents the current object. (继承自 NetMessageBase。) |
扩展方法| 名称 | 说明 | |
|---|---|---|
 | ToJsonString |
获取当前对象的JSON格式表示的字符串。 (由 HslExtension 定义。)Gets the string represented by the JSON format of the current object. |
