我在C＃中编写一个监视文件夹的代码，当文件被创建时，代码会执行一些操作并将结果写入日志文件。 我有这种非常奇怪的行为。当我在监视文件夹中创建文件时，处理更改的函数执行twise！即使它只是一个变化事件。 最初我使用FileSystemWatcher。但我查了之后，我发现它发出了稳定的稳定性，所以我改用了MyFileSystemWatcher，这是一个更加稳定的扼杀。但我仍然在我的日志文件中得到重复。我不知道为什么查找更改的代码会运行twise。这是代码示例
protected void Folder_Watch(string path)
{
if (!Directory.Exists(path))
{
try
{
System.IO.Directory.CreateDirectory(path);
}
catch (Exception ex)
{
File.AppendAllText(logPath + "\\SSHErrorLog.log", "[]*******" + DateTime.Now + " Error: " + ex.Message.ToString() + Environment.NewLine);
}
}
MyFileSystemWatcher m_Watcher = new MyFileSystemWatcher(path);
//m_Watcher.Path = path;
m_Watcher.Filter = "*.*";
m_Watcher.NotifyFilter = NotifyFilters.FileName;
m_Watcher.Created += new FileSystemEventHandler(OnChanged);
m_Watcher.EnableRaisingEvents = true;
}
这是onChange函数
private void OnChanged(object source, FileSystemEventArgs e)
{
File.AppendAllText(logPath + "\\SSHConnectionLog.log", "[]*******" + DateTime.Now + " OnChanged function: " + Environment.NewLine);
// Decrypt the file.
DecryptFile(keyPath + "\\id_rsa_Encrypted", keyPath + "\\id_rsa", sSecretKey);
// Remove the Key from memory.
//PKey = new PrivateKeyFile(keyPath + "\\id_rsa");
keyResult.Text = "RSA keys Were Generated at:" + keyPath;
//ScpClient client = new ScpClient("remnux", "adi", PKey);
Chilkat.SFtp client = new Chilkat.SFtp();
string[] tempPath = e.FullPath.Split('\\');
string fullPathNew = string.Empty;
for (int i = 0; i < tempPath.Length - 1; i++)
{
fullPathNew += tempPath[i];
}
if (Directory.Exists(fullPathNew))
{
sshConnect(client);
File_Upload(e.FullPath, client);
}
else
{
try
{
sshConnect(client);
System.IO.Directory.CreateDirectory(fullPathNew);
File_Upload(e.FullPath, client);
}
catch (Exception ex)
{
File.AppendAllText(logPath + "\\SSHErrorLog.log", "[]*******" + DateTime.Now + " Error in OnChanged function: " + ex.Message.ToString() + Environment.NewLine);
}
}
}

处理了onChange函数。添加时间和文件名以处理重复的匹配
private void OnChanged(object source, FileSystemEventArgs e)
{
string[] temp = new string[3];
string[] tempNow = new string[3];
string[] tempSeconds = new string[2];
string[] tempNowSeconds = new string[2];
int temp1 = 0;
int temp2 = 0;
if(string.IsNullOrEmpty(changeName))
{
changeName = e.Name;
}
if (string.IsNullOrEmpty(changeTime))
{
changeTime = DateTime.Now.ToString();
temp = this.changeTime.Split(':');
tempNow = DateTime.Now.ToString().Split(':');
tempSeconds = temp[2].Split(' ');
tempNowSeconds = temp[2].Split(' ');
temp1 = Convert.ToInt16(tempSeconds[0]);
temp2 = Convert.ToInt16(tempNowSeconds[0]);
// Decrypt the file.
DecryptFile(keyPath + "\\id_rsa_Encrypted", keyPath + "\\id_rsa", sSecretKey);
// Remove the Key from memory.
PKey = new PrivateKeyFile(keyPath + "\\id_rsa");
keyResult.Text = "RSA keys Were Generated at:" + keyPath;
ScpClient client = new ScpClient("remnux", "adi", PKey);
string[] tempPath = e.FullPath.Split('\\');
string fullPathNew = string.Empty;
for (int i = 0; i < tempPath.Length - 1; i++)
{
fullPathNew += tempPath[i];
}
if (Directory.Exists(fullPathNew))
{
sshConnect(client);
File_Upload(e.FullPath, client);
}
else
{
try
{
sshConnect(client);
System.IO.Directory.CreateDirectory(fullPathNew);
File_Upload(e.FullPath, client);
}
catch (Exception ex)
{
File.AppendAllText(logPath + "\\SSHErrorLog.log", "[]*******" + DateTime.Now + " Error in OnChanged function: " + ex.Message.ToString() + Environment.NewLine);
}
}
}
if (!this.changeTime.Equals(DateTime.Now.ToString()))
{
temp = this.changeTime.Split(':');
tempNow = DateTime.Now.ToString().Split(':');
tempSeconds = temp[2].Split(' ');
tempNowSeconds = temp[2].Split(' ');
temp1 = Convert.ToInt16(tempSeconds[0]);
temp2 = Convert.ToInt16(tempNowSeconds[0]);
if (temp[2] != tempNow[2])
{
if ((temp1 < temp2 + 10 || temp1 > temp2 +40) && e.Name != changeName)
{
// Decrypt the file.
DecryptFile(keyPath + "\\id_rsa_Encrypted", keyPath + "\\id_rsa", sSecretKey);
// Remove the Key from memory.
PKey = new PrivateKeyFile(keyPath + "\\id_rsa");

ScpClient client = new ScpClient("remnux", "adi", PKey);
string[] tempPath = e.FullPath.Split('\\');
string fullPathNew = string.Empty;
for (int i = 0; i < tempPath.Length - 1; i++)
{
fullPathNew += tempPath[i];
}
if (Directory.Exists(fullPathNew))
{
sshConnect(client);
File_Upload(e.FullPath, client);
}
else
{
try
{

System.IO.Directory.CreateDirectory(fullPathNew);
File_Upload(e.FullPath, client);
}
catch (Exception ex)
{
File.AppendAllText(logPath + "\\SSHErrorLog.log", "[]*******" + DateTime.Now + " Error in OnChanged function(second if): " + ex.Message.ToString() + Environment.NewLine);
