在异步调用C#中包装一个同步函数 [英] Wrap a synchronous function in Asynchronous call c#

问题描述

我有一个服务器，该服务器必须通过网络轮询设备，以获取信息，对其进行处理，然后将其发送给用户. 设备调查成为同步阻止功能.

I have a server, which must poll an equipment through the network, to obtain information, process it and then send it to the users. The equipment survey becomes a synchronous blocking function.

我的问题是:

如何创建自己的异步功能版本以使用Task或其他异步模式执行此功能?

How to create an own asynchronous function version to perform this function using Task or another asynchronous pattern???

考虑以下代码以从设备获取信息:

Consider the following code to get information from equipment:

IEnumerable<Logs> GetDataFromEquipment(string ipAddress)
        {
            Equipment equipment = new Equipment();
            //Open communication with equipment. Blocking code.
            int handler = equipment.OpenCommunication(ipAddress);
            //get data from equipment. Blocking code.
            IEnumerable<Logs> logs = equipment.GetLogs(handler);
            //close communication with equipment
            equipment.CloseCommunication(handler);

            return logs;
        }

谢谢

推荐答案

您可以使用async/await

You can use async/await

 public async Task<IEnumerable<Logs>> GetDataFromEquipment(string ipAddress)
    {

        var task = Task.Run(() =>
        {
            Equipment equipment = new Equipment();
            //Open communication with equipment. Blocking code.
            int handler = equipment.OpenCommunication(ipAddress);
            //get data from equipment. Blocking code.
            IEnumerable<Logs> logs = equipment.GetLogs(handler);
            //close communication with equipment
            equipment.CloseCommunication(handler);

            return logs;
        });

        return await task;
    }
