语法 public virtual Task<OperateResult> WriteAsync(
string address,
byte[] value
)
Public Overridable Function WriteAsync (
address As String,
value As Byte()
) As Task(Of OperateResult)
public:
virtual Task<OperateResult^>^ WriteAsync(
String^ address,
array<unsigned char>^ value
)
abstract WriteAsync :
address : string *
value : byte[] -> Task<OperateResult>
override WriteAsync :
address : string *
value : byte[] -> Task<OperateResult>

TaskOperateResult带有成功标识的结果类对象
实现
IReadWriteNetWriteAsync(String, Byte)示例
以下为三菱的连接对象示例,其他的设备读写情况参照下面的代码:
MelsecMcNet melsec_net = new MelsecMcNet( "192.168.0.100", 6000 );
await melsec_net.WriteAsync( "D100", (short)123 );
OperateResult write = await melsec_net.WriteAsync( "D100", (short)123 );
if (write.IsSuccess)
{
}
else
{
}
