public partial class Service1 : ServiceBase
{
System.Threading.Timer recordTimer;
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
}
protected override void OnStop()
{
}
}
只要在OnStart里完成你的功能代码即可。本例中我们做一个定时向本地文件写记录的功能。
public class FileOpetation
{
///
/// 保存至本地文件
///
///
///
public static void SaveRecord(string content)
{
if (string.IsNullOrEmpty(content))
{
return;
}
FileStream fileStream = null;
StreamWriter streamWriter = null;
try
{
string path = Path.Combine(System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase, string.Format("{0:yyyyMMdd}", DateTime.Now));
using (fileStream = new FileStream(path, FileMode.Append, FileAccess.Write))
{
using (streamWriter = new StreamWriter(fileStream))
{
streamWriter.Write(content);
if (streamWriter != null)
{
streamWriter.Close();
}
}
if (fileStream != null)
{
fileStream.Close();
}
}
}
catch { }
}
}
那么在Service1中调用,
public partial class Service1 : ServiceBase
{
System.Threading.Timer recordTimer;
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
IntialSaveRecord();
}
protected override void OnStop()
{
if (recordTimer != null)
{
recordTimer.Dispose();
}
}
private void IntialSaveRecord()
{
TimerCallback timerCallback = new TimerCallback(CallbackTask);
AutoResetEvent autoEvent = new AutoResetEvent(false);
recordTimer = new System.Threading.Timer(timerCallback, autoEvent, 10000, 60000 * 10);
}
private void CallbackTask(Object stateInfo)
{
FileOpetation.SaveRecord(string.Format(@"当前记录时间:{0},状况:程序运行正常!", DateTime.Now));
}
}
这样服务算是写的差不多了,下面添加一个安装类,用于安装。
安装代码,
class Program
{
static void Main(string[] args)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
string sysDisk = System.Environment.SystemDirectory.Substring(0,3);
string dotNetPath = sysDisk + @"WINDOWS\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe";//因为当前用的是4.0的环境
string serviceEXEPath = Application.StartupPath+@"\MyFirstWindowsService.exe";//把服务的exe程序拷贝到了当前运行目录下,所以用此路径
string serviceInstallCommand = string.Format(@"{0} {1}", dotNetPath, serviceEXEPath);//安装服务时使用的dos命令
string serviceUninstallCommand = string.Format(@"{0} -U {1}", dotNetPath, serviceEXEPath);//卸载服务时使用的dos命令
try
{
if (File.Exists(dotNetPath))
{
string[] cmd = new string[] { serviceUninstallCommand };
string ss = Cmd(cmd);
CloseProcess("cmd.exe");
}
}
catch
{
}
Thread.Sleep(1000);
try
{
if (File.Exists(dotNetPath))
{
string[] cmd = new string[] { serviceInstallCommand };
string ss = Cmd(cmd);
CloseProcess("cmd.exe");
}
}
catch
{
}
try
{
Thread.Sleep(3000);
ServiceController sc = new ServiceController("MyFirstWindowsService");
if (sc != null && (sc.Status.Equals(ServiceControllerStatus.Stopped)) ||
(sc.Status.Equals(ServiceControllerStatus.StopPending)))
{
sc.Start();
}
sc.Refresh();
}
catch
{
}
}
///
/// 运行CMD命令
///
/// 命令
///
public static string Cmd(string[] cmd)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardInput.AutoFlush = true;
for (int i = 0; i < cmd.Length; i++)
{
p.StandardInput.WriteLine(cmd[i].ToString());
}
p.StandardInput.WriteLine("exit");
string strRst = p.StandardOutput.ReadToEnd();
p.WaitForExit();
p.Close();
return strRst;
}
///
/// 关闭进程
///
/// 进程名称
///
public static bool CloseProcess(string ProcName)
{
bool result = false;
System.Collections.ArrayList procList = new System.Collections.ArrayList();
string tempName = "";
int begpos;
int endpos;
foreach (System.Diagnostics.Process thisProc in System.Diagnostics.Process.GetProcesses())
{
tempName = thisProc.ToString();
begpos = tempName.IndexOf("(") + 1;
endpos = tempName.IndexOf(")");
tempName = tempName.Substring(begpos, endpos - begpos);
procList.Add(tempName);
if (tempName == ProcName)
{
if (!thisProc.CloseMainWindow())
thisProc.Kill(); // 当发送关闭窗口命令无效时强行结束进程
result = true;
}
}
return result;
}
}
这段代码其实可以放在项目中的某个地方,或单独执行程序中,只好设置好dotNetPath和serviceEXEPath路径就可以了。
运行完后,如图,
这样,一个windows服务安装成功了。
