命名空间:
HslCommunication.Profinet.Inovance
程序集:
HslCommunication (在 HslCommunication.dll 中) 版本:12.1.2.0 (12.1.2.0)
语法 public override Task<OperateResult<string>> ReadStringAsync(
string address,
ushort length,
Encoding encoding
)
Public Overrides Function ReadStringAsync (
address As String,
length As UShort,
encoding As Encoding
) As Task(Of OperateResult(Of String))
public:
virtual Task<OperateResult<String^>^>^ ReadStringAsync(
String^ address,
unsigned short length,
Encoding^ encoding
) override
abstract ReadStringAsync :
address : string *
length : uint16 *
encoding : Encoding -> Task<OperateResult<string>>
override ReadStringAsync :
address : string *
length : uint16 *
encoding : Encoding -> Task<OperateResult<string>>
参数
- address
- 类型:System.String
起始地址 - length
- 类型:System.UInt16
数据长度 - encoding
- 类型:System.Text.Encoding
指定的自定义的编码
返回值
类型:
Task<OperateResult<String>>带有成功标识的string数据
实现
IReadWriteNet.ReadStringAsync(String, UInt16, Encoding)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 );
string d100_value = melsec_net.ReadString( "D100", 5 ).Content;
OperateResult<string> R_d100_value = melsec_net.ReadString( "D100", 5, Encoding.Unicode );
if (R_d100_value.IsSuccess)
{
string value = R_d100_value.Content;
}
else
{
}
