public partial class Loginform : Form
{      
    public Loginform()
    {
        InitializeComponent();
    }
    private void btnlogin_Click(object sender, EventArgs e)
    {
        string dir = "D://Login.hhh";
        if (!File.Exists(dir))
        {
            File.Create(dir);
        }
        string filePath = dir;
        string s = System.Environment.GetEnvironmentVariable("COMPUTERNAME");
        string s1 = getIP();
        using (StreamWriter swrObj = new StreamWriter(filePath, true))
        {
            swrObj.Write(s1 + "|" + s + "|" + Txtusername.Text + "|" + "user logged in on :|" + DateTime.Now.ToShortDateString() + " at " + DateTime.Now.ToShortTimeString());
            swrObj.Write("'t't");
            swrObj.Write("'t't");
            swrObj.WriteLine();
            MessageBox.Show("Login success");
        }
    }
    private void Loginform_Load(object sender, EventArgs e)
    { 
    }
    private string getIP()
    { 
        IPHostEntry host;
        string localIP = "?";
        host = Dns.GetHostEntry(Dns.GetHostName());
        foreach (IPAddress ip in host.AddressList)
        {
            if (ip.AddressFamily.ToString() == "InterNetwork")
            {
                localIP = ip.ToString();
            }
        }
        return  localIP;
    }
 }

我想在c#中为项目应用日志文件，我使用上述方法来创建日志文件以获取系统名称，IP地址和用户登录，但它适用于单用户环境，如果应用于多用户环境，如何获取所有用户的日志信息?谁来帮帮我?

c# 4.0 -如何在c#中获取多个用户的日志文件

我假设您想为每个用户创建日志文件，那么您可以这样做:-

 private void btnlogin_Click(object sender, EventArgs e)
    {
        string s1 = getIP();
        string dir = "D://"+s1+"-"+DateTime.Now+"Login.hhh";
        if (!File.Exists(dir))
        {
            File.Create(dir);
        }
        string filePath = dir;
        string s = System.Environment.GetEnvironmentVariable("COMPUTERNAME");
        using (StreamWriter swrObj = new StreamWriter(filePath, true))
        {
            swrObj.Write(s1 + "|" + s + "|" + Txtusername.Text + "|" + "user logged in on :|" + DateTime.Now.ToShortDateString() + " at " + DateTime.Now.ToShortTimeString());
            swrObj.Write("'t't");
            swrObj.Write("'t't");
            swrObj.WriteLine();
            MessageBox.Show("Login success");
        }
    }
