复制

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)
IReadWriteNetReadAsync(String, UInt16)

备注

地址默认使用功能码03，如果需要指定其他的功能码地址，需要手动指定功能码，例如：x=4;100, x=9;100, x=10;100, 当然也可以写成 x=0x0A;100
The address uses function code 03 by default. If you need to specify other function code addresses, you need to manually specify the function code, for example: x=4;100, x=9;100, x=10;100, of course, it can also be written as x=0x0A; 100
