asp.net core|asp.net 中winform防止被调用的实现方法

 

 代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Diagnostics;
using System.Management;

namespace 不允许外部调用
{
    static class Program
    {
        ///

        /// 应用程序的主入口点。
        ///

        [STAThread]
        static void Main(string[] args)
        {

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Process proc = Process.GetCurrentProcess();
            if (!FillDetailUseWmi(proc.Id).ToLower().Equals("explorer".ToLower()))
            {
                MessageBox.Show("该程序禁止外部程序调用。");
                Application.ExitThread();
            }
            else
            {
                Application.Run(new Form1());
            }
        }

        ////

        /// 使用Wmi获取指定进程的创建者等信息
        ///

        /// 进程ID
        private static string FillDetailUseWmi(int pID)
        {
            string pname = string.Empty;
            ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_Process Where ProcessID=" + pID);
            ManagementObjectCollection moc = searcher.Get();
            ManagementOperationObserver observer = new ManagementOperationObserver();
            HandleObjectReady hor = new HandleObjectReady();
            //监测异步方法是否已成功返回
            observer.ObjectReady += new ObjectReadyEventHandler(hor.Done);
            foreach (ManagementObject mo in moc)
            {
                //异步调用该对象的GetOwner方法，获取进程创建者
                mo.InvokeMethod(observer, "GetOwner", null);
                //等待异步调用返回
                while (!hor.Complete)
                {
                    System.Threading.Thread.Sleep(500);
                }
                string user = "";
                //判断获取用户名的操作是否成功
                if (hor.Obj["returnValue"].ToString() == "0")
                {
                    user = hor.Obj.Properties["User"].Value.ToString();
                }
                if (mo["ParentProcessID"] != null )
                {
                    //根据父进程ID获取父进程名称
                    int vpID=Convert.ToInt32(mo["ParentProcessID"]);
                    pname = Process.GetProcessById(vpID).ProcessName;
                }
            }
            //释放资源
            searcher.Dispose();
            searcher = null;
            moc.Dispose();
            moc = null;
            observer = null;
            hor = null;
            return pname;
        }
        /**/
        ///

        /// 该类用于监测Wmi异步调用方法是否已经返回
        ///

        public class HandleObjectReady
        {
            private bool complete = false;
            private ManagementBaseObject obj;
            public void Done(object sender, ObjectReadyEventArgs e)
            {
                complete = true;
                obj = e.NewObject;
            }
            public bool Complete
            {
                get
                {
                    return complete;
                }
            }
            public ManagementBaseObject Obj
            {
                get
                {
                    return obj;
                }
            }
        }
    }
}

需要添加.Net引用 System.Management
