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：

namespace WfpApp { public partial class Form2 : Form { object obj = new object(); public Form2() { InitializeComponent(); System.Threading.Thread thread; string[] users = new string[] { "zkk", "admin", "administrator", "soft", "iany", "nec", "necsl" }; for (int i = 0; i < users.Length; i++) { thread = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(WriteLock)); thread.Start(users[i]); } } public void WriteThread(object user) { string path = System.Windows.Forms.Application.StartupPath + "app"; if (!System.IO.Directory.Exists(path)) System.IO.Directory.CreateDirectory(path); path = path + "" + DateTime.Now.ToString("yyyyMMdd") + ".txt"; StringBuilder sb = new StringBuilder(); sb.AppendLine("----------------------------" + DateTime.Now.ToString("yyyy-MM-dd HH: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.FileStream fileStream = new System.IO.FileStream(path, System.IO.FileMode.Append, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite); System.IO.StreamWriter sw = new System.IO.StreamWriter(fileStream, Encoding.Default); sw.Write(sb.ToString()); sw.Close(); sw.Dispose(); fileStream.Close(); fileStream.Dispose(); } public void WriteLock(object user) { lock (obj) { string path = System.Windows.Forms.Application.StartupPath + "app"; if (!System.IO.Directory.Exists(path)) System.IO.Directory.CreateDirectory(path); path = path + "" + DateTime.Now.ToString("yyyyMMdd") + ".txt"; StringBuilder sb = new StringBuilder(); sb.AppendLine("----------------------------" + DateTime.Now.ToString("yyyy-MM-dd HH: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.FileStream fileStream = new System.IO.FileStream(path, System.IO.FileMode.Append, System.IO.FileAccess.Write); System.IO.StreamWriter sw = new System.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。
