public override Task<OperateResult<byte[]>> ReadAsync(
	string address,
	ushort length
)

Public Overrides Function ReadAsync ( 
	address As String,
	length As UShort
) As Task(Of OperateResult(Of Byte()))

public:
virtual Task<OperateResult<array<unsigned char>^>^>^ ReadAsync(
	String^ address, 
	unsigned short length
) override

abstract ReadAsync : 
        address : string * 
        length : uint16 -> Task<OperateResult<byte[]>> 
override ReadAsync : 
        address : string * 
        length : uint16 -> Task<OperateResult<byte[]>>

参数

address: 类型：SystemString
数据地址
length: 类型：SystemUInt16
数据长度

返回值

类型：TaskOperateResultByte
带有成功标识的byte[]数组

实现

IReadWriteNetReadAsync(String, UInt16)

备注

length没有任何意义，需要传入原始的字节报文，例如：stx=9;00 00 00 00 00 06 01 03 00 64 00 01，stx得值用于获取数据移除的前置报文头，可以不填写
length has no meaning, you need to pass in the original byte message, for example: stx=9;00 00 00 00 00 06 01 03 00 64 00 01, the value of stx is used to obtain the preamble header for data removal, can be left blank
