1.新建winform程序，添加一个Panel控件和一个button控件，winform窗体命名为：Mainform；
2.新建一个类文件，方便引用，命名为：exetowinform；
3.Mainform中cs代码如下：
exetowinform fr = null;
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog Oppf = new OpenFileDialog();
Oppf.ShowDialog();
if (Oppf.FileName != "")
{
panel1.Controls.Clear();
fr = new exetowinform(panel1, "");
fr.Start(Oppf.FileName);
}
}
4.exetowinform类文件代码如下：
public class exetowinform
{
EventHandler appIdleEvent = null;
Control ParentCon = null;
string strGUID = "";
public exetowinform(Control C, string Titlestr)
{
appIdleEvent = new EventHandler(Application_Idle);
ParentCon = C;
strGUID = Titlestr;
}

info.WindowStyle = ProcessWindowStyle.Minimized;
m_AppProcess = System.Diagnostics.Process.Start(info);
m_AppProcess.WaitForInputIdle();
Application.Idle += appIdleEvent;
}
catch
{
if (m_AppProcess != null)
{
if (!m_AppProcess.HasExited)
m_AppProcess.Kill();
m_AppProcess = null;
}
}
return m_AppProcess.Handle;
}

return;
}
while (m_AppProcess.MainWindowHandle == IntPtr.Zero)
{
Thread.Sleep(100);
m_AppProcess.Refresh();
}
Application.Idle -= appIdleEvent;
EmbedProcess(m_AppProcess, ParentCon);
