C#实现多线程写入同一个文件的方法
本文实例讲述了C#实现多线程写入同一个文件的方法。分享给大家供大家参考。具体实现方法如下：
namespaceWfpApp
{
publicpartialclassForm2:Form
{
objectobj=newobject();
publicForm2()
{
InitializeComponent();
System.Threading.Threadthread;
string[]users=newstring[]{"zkk","admin","administrator","soft","iany","nec","necsl"};
for(inti=0;i<users.Length;i++)
{
thread=newSystem.Threading.Thread(newSystem.Threading.ParameterizedThreadStart(WriteLock));
thread.Start(users[i]);
}
}
publicvoidWriteThread(objectuser)
{
stringpath=System.Windows.Forms.Application.StartupPath+"\\app\\";
if(!System.IO.Directory.Exists(path))
System.IO.Directory.CreateDirectory(path);
path=path+"\\"+DateTime.Now.ToString("yyyyMMdd")+".txt";
StringBuildersb=newStringBuilder();
sb.AppendLine("----------------------------"+DateTime.Now.ToString("yyyy-MM-ddHH:mm:ss.fff")+"--------------------------");
sb.AppendLine(user.ToString());
sb.AppendLine("---------------------------------------------------------------------------------");
sb.AppendLine();
//if(!System.IO.File.Exists(path))
//System.IO.File.Create(path).Close();
System.IO.FileStreamfileStream=newSystem.IO.FileStream(path,System.IO.FileMode.Append,System.IO.FileAccess.Write,System.IO.FileShare.ReadWrite);
System.IO.StreamWritersw=newSystem.IO.StreamWriter(fileStream,Encoding.Default);
sw.Write(sb.ToString());
sw.Close();
sw.Dispose();
fileStream.Close();
fileStream.Dispose();
}
publicvoidWriteLock(objectuser)
{
lock(obj)
{
stringpath=System.Windows.Forms.Application.StartupPath+"\\app\\";
if(!System.IO.Directory.Exists(path))
System.IO.Directory.CreateDirectory(path);
path=path+"\\"+DateTime.Now.ToString("yyyyMMdd")+".txt";
StringBuildersb=newStringBuilder();
sb.AppendLine("----------------------------"+DateTime.Now.ToString("yyyy-MM-ddHH:mm:ss.fff")+"--------------------------");
sb.AppendLine(user.ToString());
sb.AppendLine("---------------------------------------------------------------------------------");
sb.AppendLine();
if(!System.IO.File.Exists(path))
System.IO.File.Create(path).Close();
System.IO.FileStreamfileStream=newSystem.IO.FileStream(path,System.IO.FileMode.Append,System.IO.FileAccess.Write);
System.IO.StreamWritersw=newSystem.IO.StreamWriter(fileStream,Encoding.Default);
sw.Write(sb.ToString());
sw.Close();
sw.Dispose();
fileStream.Close();
fileStream.Dispose();
}
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
