调用windows服务来监视文件夹状态

记录一下过程

打开vs 新建一个解决方案再新建一个windows服务项目，再新建一个数据库处理类库直接用的SqlHelper,再添加一个应用程序配置文件app.config

项目结构如下：



windows服务代码

1 using System;
2 using System.Collections.Generic;
3 using System.ComponentModel;
4 using System.Data;
5 using System.Diagnostics;
6 using System.Linq;
7 using System.ServiceProcess;
8 using System.Text;
9 using System.Diagnostics.PerformanceData;
10 using System.IO;
11 using System.Data.SqlClient;
12 namespace FileMonitorService
13 {
14 public partial class Service1 : ServiceBase
15 {
16 private System.Diagnostics.PerformanceCounter fileCreateCounter;
17 private System.Diagnostics.PerformanceCounter fileDeleteCounter;
18 private System.Diagnostics.PerformanceCounter fileRenameCounter;
19 private System.Diagnostics.PerformanceCounter fileChangeCounter;
20 private bool servicePaused = false;
21 public Service1()
22 {
23 InitializeComponent();
24 }
25 protected override void OnStart(string[] args)
26 {
27 FileSystemWatcher curWatcher = new FileSystemWatcher();
28
29 curWatcher.BeginInit();
30 curWatcher.IncludeSubdirectories = true;
31 curWatcher.Path =
32 System.Configuration.ConfigurationSettings.AppSettings["FileMonitorDirectory"];
33 curWatcher.Changed += new FileSystemEventHandler(OnFileChanged);
34 curWatcher.Created += new FileSystemEventHandler(OnFileCreated);
35 curWatcher.Deleted += new FileSystemEventHandler(OnFileDeleted);
36 curWatcher.Renamed += new RenamedEventHandler(OnFileRenamed);
37 curWatcher.EnableRaisingEvents = true;
38 curWatcher.EndInit();
39
40 }
41 private void OnFileChanged(Object source, FileSystemEventArgs e)
42 {
43 if (servicePaused == false)
44 {
45 Writelog(DateTime.Now.ToString() + "修改了" + e.FullPath.ToString(), e.Name);
46 }
47 }
48
49 private void OnFileRenamed(Object source, RenamedEventArgs e)
50 {
51 if (servicePaused == false)
52 {
53 Writelog(DateTime.Now.ToString() + "重命名了" + e.FullPath.ToString(), e.Name);
54 }
55 }
56
57 private void OnFileCreated(Object source, FileSystemEventArgs e)
58 {
59 if (servicePaused == false)
60 {
61 //File.Open
62
63 Writelog(DateTime.Now.ToString() + "创建了" + e.FullPath.ToString(),e.Name);
64
65 }
66 }
67 protected void Writelog(string log,string name)
68 {
69 string logpath = System.Configuration.ConfigurationSettings.AppSettings["log"];
70 StreamWriter sw = new StreamWriter(logpath,true,System.Text.Encoding.Default);
71 try
72 {
73 //SqlConnection conn = new SqlConnection("Password=123456;Persist Security Info=True;User ID=sa;Initial Catalog=FileMonitorServiceLog;Data Source=192.168.3.22");
74 //SqlCommand cmd = new SqlCommand("insert into LogList(logcontent)values('" + log + "')", conn);
75 //conn.Open();
76 //cmd.ExecuteNonQuery();
77 //conn.Close();
78 Rifa.ITPlatform.DB.SqlHelper sqlh = new Rifa.ITPlatform.DB.SqlHelper();
79 sqlh.RunSqlStr("insert into LogList(logcontent,directory)values('" + log + "','" + name + "')");
80 sw.WriteLine(log);
81 sw.Flush();
82 sw.Close();
83 }
84 catch(Exception ex)
85 {
86 sw.WriteLine("文件写入失败"+ex.Message);
87 sw.Close();
88 }
89
90 }
91
92 private void OnFileDeleted(Object source, FileSystemEventArgs e)
93 {
94 if (servicePaused == false)
95 {
96 Writelog(DateTime.Now.ToString() + "删除了" + e.FullPath.ToString(), e.Name);
97 }
98 }
99
100 protected override void OnStop()
101 {
102 if (fileChangeCounter.RawValue != 0)
103 {
104 fileChangeCounter.IncrementBy(-fileChangeCounter.RawValue);
105 }
106 if (fileDeleteCounter.RawValue != 0)
107 {
108 fileDeleteCounter.IncrementBy(-fileDeleteCounter.RawValue);
109 }
110 if (fileRenameCounter.RawValue != 0)
111 {
112 fileRenameCounter.IncrementBy(-fileRenameCounter.RawValue);
113 }
114 if (fileCreateCounter.RawValue != 0)
115 {
116 fileCreateCounter.IncrementBy(-fileCreateCounter.RawValue);
117 }
118 }
119 protected override void OnPause()
120 {
121 servicePaused = true;
122 }
123
124 protected override void OnContinue()
125 {
126 servicePaused = false;
127 }
128
129 }
130 }
app.config配置信息

1 <?xml version="1.0" encoding="utf-8" ?>
2 <configuration>
3 <appSettings>
4 <add key="FileMonitorDirectory" value="E:\learn_project\WindowsService1\test\"/>
5 <add key="log" value="E:\learn_project\WindowsService1\log.txt"/>
6 </appSettings>
7 <connectionStrings>
8 <add name="conn" connectionString="Password=123456;Persist Security Info=True;User ID=sa;Initial Catalog=FileMonitorServiceLog;Data Source=192.168.3.22" />
9 </connectionStrings>
10 </configuration>
把应用程序设置成winodws服务的命令如下

sc create FileMonitorService type= own start= auto binpath= E:\learn_project\WindowsService1\FileMonitorService\bin\Debug\FileMonitorService.exe displayname= FileMonitorService

然后到服务里启动这个服务就可以了

最后来一张数据库表信息的截图
