为什么这不起作用，但是类似的电源壳操作却是

Question

我使用

dism

1. 启用了所有需要的选项
   

Method：

        public object SetKeyStatus(Dictionary<string, string> request)
        {
            if (!request.ContainsKey("Key") || !request.ContainsKey("Blocked"))
            {
                return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_INVALID_ARGUMENT, "Missing 'Key' or 'Blocked' parameter.");
            }

            string key = request["Key"];
            if (!bool.TryParse(request["Blocked"], out bool disable))
            {
                return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_INVALID_ARGUMENT, "Invalid 'Blocked' value. Expected 'true' or 'false'.");
            }

            try
            {
                string query = $"SELECT * FROM WEKF_PredefinedKey WHERE Id = '{key}'";

                using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(@"root\standardcimv2\embedded", query))
                {
                    foreach (ManagementObject obj in searcher.Get())
                    {
                        obj["Enabled"] = disable ? 1 : 0 ; // true = Disable (block), false = Enable (allow)

                        PutOptions options = new PutOptions { Type = PutType.UpdateOnly};
                        ManagementPath path = obj.Put(options);
                        obj.Get(); // Ensure the object updates its internal state
                        logger.log($"[*********]Result : {path}");
                        //ManagementPath path = obj.Put();
                        //logger.log($"[*********]Result : {path}");
                        return GenerateSuccessResponse<object>("setkeystatus", key, disable);
                    }
                }

                throw new GULException(GULErrorCode.ERR_KEYBOARD_FILTER_KEY_NOT_FOUND, $"Key '{key}' not found.");
            }
            catch (ManagementException ex)
            {
                return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_WMI_WRITE_FAILED, $"WMI write operation failed: {ex.Message}");
            }
            catch (GULException gex)
            {
                return GenerateErrorResponse<object>(gex.ErrorCode, gex.Message);
            }
            catch (Exception ex)
            {
                return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_PROCESSING_EXCEPTION, $"Error setting key status: {ex.Message}");
            }
        }

它不能启用过滤器，并且CAD处于活动状态。它作为系统服务运行并具有本地系统特权。

但这有效

$key = "Ctrl+Alt+Del"
$setkey = Get-WMIObject -class WEKF_PredefinedKey –computer localhost –namespace  root\standardcimv2\embedded | where {$_.Id -eq "$key"};
$setkey.Id = $key
$setkey.Enabled = 1;
$setkey.Put();

我想念什么？

您的方法无法正确更新

Enabled

Answer 1

Put()

.

上调用

ManagementObject

。

确定启用属性的设置正确。

在

Put()

上保存更改。
完成您的方法：

• ManagementObject

  请检查一下。这应该确保正确更新

  public object SetKeyStatus(Dictionary<string, string> request)
  {
      if (!request.ContainsKey("Key") || !request.ContainsKey("Blocked"))
      {
          return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_INVALID_ARGUMENT, "Missing 'Key' or 'Blocked' parameter.");
      }
  
      string key = request["Key"];
      if (!bool.TryParse(request["Blocked"], out bool disable))
      {
          return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_INVALID_ARGUMENT, "Invalid 'Blocked' value. Expected 'true' or 'false'.");
      }
  
      try
      {
          string query = $"SELECT * FROM WEKF_PredefinedKey WHERE Id = '{key}'";
  
          using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(@"root\standardcimv2\embedded", query))
          {
              foreach (ManagementObject obj in searcher.Get())
              {
                  obj["Enabled"] = disable ? 1 : 0; // true = Disable (block), false = Enable (allow)
  
                  PutOptions options = new PutOptions { Type = PutType.UpdateOnly };
                  obj.Put(options); // Save the changes
                  obj.Get(); // Ensure the object updates its internal state
  
                  logger.log($"[*********]Result : {obj.Path}");
                  return GenerateSuccessResponse<object>("setkeystatus", key, disable);
              }
          }
  
          throw new GULException(GULErrorCode.ERR_KEYBOARD_FILTER_KEY_NOT_FOUND, $"Key '{key}' not found.");
      }
      catch (ManagementException ex)
      {
          return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_WMI_WRITE_FAILED, $"WMI write operation failed: {ex.Message}");
      }
      catch (GULException gex)
      {
          return GenerateErrorResponse<object>(gex.ErrorCode, gex.Message);
      }
      catch (Exception ex)
      {
          return GenerateErrorResponse<object>(GULErrorCode.ERR_KEYBOARD_FILTER_PROCESSING_EXCEPTION, $"Error setting key status: {ex.Message}");
      }
  }

属性。
