我正在使用C#的RegistryManager类.这是链接!.让我分享我正在使用的C#代码，

I am using RegistryManager class of C#. Here's a link!. Let me share C# code which I am using for same,

using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Microsoft.Azure.Devices;

public static class EnableDevice
{
    static RegistryManager registryManager;
    static string iotHubConnectionString = Environment.GetEnvironmentVariable("iotHubConnectionString");

    [FunctionName("EnableDevice")]
    public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)] HttpRequest req,
        ILogger log)
    {
        JObject response = new JObject();
        try
        {
            string deviceId = req.Query["device_id"];
            if (string.IsNullOrEmpty(deviceId))
            {
                response.Add("message", "Please provide valid device_id in request params or in the request body");
                response.Add("code", 400);
                return new BadRequestObjectResult(response);
            }

            registryManager = RegistryManager.CreateFromConnectionString(iotHubConnectionString);
            Device device = await registryManager.GetDeviceAsync(deviceId);
            if (device == null)
            {
                response.Add("message", $"Error while enabling device: Device with {deviceId} not found.");
                response.Add("code", 400);
                return new BadRequestObjectResult(response);
            }
            device.Status = DeviceStatus.Enabled;  // DeviceStatus.Disabled to Disable device
            await registryManager.UpdateDeviceAsync(device);

            response.Add("message", "Device enabled successfully");
            response.Add("code", 200);
            return new OkObjectResult(response);
        }
        catch (Exception e)
        {
            response.Add("message", e.Message);
            response.Add("stacktrace", e.StackTrace);
            response.Add("code", 500);
            return new BadRequestObjectResult(response);
        }
    }
}
