string userName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

使用实际登录用户的System.Windows.Forms.SystemInformation.UserName作为环境。UserName仍然返回当前进程正在使用的帐户。

如果你在一个用户网络中，那么用户名将是不同的:

Environment.UserName
- Will Display format : 'Username'

而不是

System.Security.Principal.WindowsIdentity.GetCurrent().Name
- Will Display format : 'NetworkName\Username'

选择您想要的格式。

下面是代码(但不是c#):

Private m_CurUser As String

Public ReadOnly Property CurrentUser As String
    Get
        If String.IsNullOrEmpty(m_CurUser) Then
            Dim who As System.Security.Principal.IIdentity = System.Security.Principal.WindowsIdentity.GetCurrent()

            If who Is Nothing Then
                m_CurUser = Environment.UserDomainName & "\" & Environment.UserName
            Else
                m_CurUser = who.Name
            End If
        End If
        Return m_CurUser
    End Get
End Property

下面是代码(现在也是c#):

private string m_CurUser;

public string CurrentUser
{
    get
    {
        if(string.IsNullOrEmpty(m_CurUser))
        {
            var who = System.Security.Principal.WindowsIdentity.GetCurrent();
            if (who == null)
                m_CurUser = System.Environment.UserDomainName + @"\" + System.Environment.UserName;
            else
                m_CurUser = who.Name;
        }
        return m_CurUser;
    }
}

String myUserName = Environment.UserName

这将为您提供输出- your_user_name

你可能还想尝试使用:

Environment.UserName;

像这样…:

string j = "Your WindowsXP Account Name is: " + Environment.UserName;

希望这对你有所帮助。
