C#一个进程监控另一进程的用户界面是否响应系统

Process.Responding Property

定义

命名空间:

System.Diagnostics

Assemblies:

System.dll, netstandard.dll, System.Diagnostics.Process.dll

获取指示进程的用户界面当前是否响应的值。

获取指示进程的用户界面当前是否响应的值。

C#

public bool Responding { get; }

属性值

Boolean

如果关联进程的用户界面当前响应系统，则为 true；否则为 false。

异常

PlatformNotSupportedException

该平台是 Windows 98 或 Windows Millennium Edition (Windows Me)；将 UseShellExecute 设置为 false，以在 Windows 98 和 Windows Me 上访问此属性。

InvalidOperationException

没有与此 Process 对象关联的进程。

NotSupportedException

你正试图访问在远程计算机上运行的进程的 Responding 属性。 此属性仅可用于本地计算机上运行的进程。

示例

以下示例启动记事本的实例。 该示例然后检索并显示关联的进程的各种属性。 该示例检测时在进程退出，并显示该进程的退出代码。

using System.Diagnostics;

namespace ProcessSample
{
    class ProcessMonitorSample
    {
        public static void Main()

                        peakVirtualMem = myProcess.PeakVirtualMemorySize64;
                        peakWorkingSet = myProcess.PeakWorkingSet64;

                        if (myProcess.Responding)
                        {
                            Console.WriteLine("Status = Running");
                        }
                        else
                        {
                            Console.WriteLine("Status = Not Responding");
                        }
                    }
                }
                while (!myProcess.WaitForExit(1000));


                Console.WriteLine();
                Console.WriteLine($"  Process exit code          : {myProcess.ExitCode}");

                // Display peak memory statistics for the process.

                Console.WriteLine($"  Peak paged memory usage    : {peakPagedMem}");
                Console.WriteLine($"  Peak virtual memory usage  : {peakVirtualMem}");
            }
        }
    }
}

注解

如果某个进程拥有的用户界面，Responding属性联系来确定进程是否正在响应用户输入的用户界面。如果接口不会立即响应Responding属性返回false。 使用此属性确定关联的进程的界面已停止响应。

如果进程不具有MainWindowHandle，此属性返回true。

应用示例

 public static void Main(string[] args)
        {
            Process[] process = Process.GetProcessesByName("应用程序进程名");
           
            if (process.Length > 0)
            {
                Process myProcess = process[0];

                do
                {
                    if (!myProcess.HasExited)
                    {
                        myProcess.Refresh();
                        if (myProcess.Responding)
                        {
                            //Console.WriteLine("Status = Running");
                        }
                        else
                        {
                            //Console.WriteLine("Status = Not Responding");
                            //无响应处理过程。。。。
                           
                        }
                    }
                }
                while (!myProcess.WaitForExit(ReadWatchTime()));
            }
        }
