【www.bbyears.com--WinForm】
WinForm是Windows下的程序，所以，可以通过判断父进程是否是explorer来达到这个目的，当时测试，是可行的，也引来了很多争论，有说判断传参的什么的，其实我觉得还是通过判断父进程来做会好一些，虽然也不是绝对安全的。
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
{

{
return complete;
}

注意事项：需要添加.Net引用 System.Management。
