C#系统调用相关代码
操作系统实验要团队协作，我对C#稍微熟悉一点，所以用csharp对大家的模块做了一下调用
中间要用到调用和监视，所以又google了一下，代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
namespace 窗体调用
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private string appName = "calc.exe";
private string baseadd = System.Windows.Forms.Application.StartupPath;
/// <summary>
/// 1. 启动外部程序，不等待其退出
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
Process.Start(appName);
MessageBox.Show(String.Format("外部程序 {0} 启动完成！", this.appName), this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
/// <summary>
/// 2. 启动外部程序，等待其退出
/// </summary>
private void button2_Click(object sender, EventArgs e)
{
try
{
Process proc = Process.Start(appName);
if (proc != null)
{
proc.WaitForExit(3000);
if (proc.HasExited)
MessageBox.Show(String.Format("外部程序 {0} 已经退出！", this.appName), this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Information);
else
{
// 如果外部程序没有结束运行则强行终止之。
proc.Kill();
MessageBox.Show(String.Format("外部程序 {0} 被强行终止！", this.appName), this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
}
}
catch (ArgumentException ex)
{
MessageBox.Show(ex.Message, this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
/// <summary>
/// 3. 启动外部程序，无限等待其退出
/// </summary>
private void button3_Click(object sender, EventArgs e)
{
try
{
Process proc = Process.Start(appName);
if (proc != null)
{
proc.WaitForExit();
MessageBox.Show(String.Format("外部程序 {0} 已经退出！", this.appName), this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
catch (ArgumentException ex)
{
MessageBox.Show(ex.Message, this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
/// <summary>
/// 4. 启动外部程序，通过事件监视其退出
/// </summary>
private void button4_Click(object sender, EventArgs e)
{
try
{
// 启动外部程序
Process proc = Process.Start(appName);
if (proc != null)
{
// 监视进程退出
proc.EnableRaisingEvents = true;
// 指定退出事件方法
proc.Exited += new EventHandler(proc_Exited);
}
}
catch (ArgumentException ex)
{
MessageBox.Show(ex.Message, this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
/// <summary>
/// 外部程序退出事件
/// </summary>
void proc_Exited(object sender, EventArgs e)
{
MessageBox.Show(String.Format("外部程序 {0} 已经退出！", this.appName), this.Text,
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
private void button5_Click(object sender, EventArgs e)
{
try
{
// 启动外部程序
string app = baseadd + "\\cppTest.exe";
Process proc = Process.Start(app);
if (proc != null)
{
// 监视进程退出
proc.EnableRaisingEvents = true;
// 指定退出事件方法
proc.Exited += new EventHandler(proc_Exited);
}
}
catch (Exception ex)
{
MessageBox.Show("Hi~,出错啦!\n"+ex.Message,"警告");
//MessageBox.Show(ex.Message, this.Text,MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
//private void button5_Click(object sender, EventArgs e)
//{
// MessageBox.Show(Process.GetCurrentProcess().MainModule.BaseAddress.ToString());
// MessageBox.Show(System.Windows.Forms.Application.StartupPath );
//}
}
}
