获取windows操作系统所有用户

一、知识点简单介绍
1. 利用WindowsApi获取
[DllImport("Netapi32.dll ")] extern static int NetUserEnum([MarshalAs(UnmanagedType.LPWStr)] string servername, int level, int filter, out IntPtr bufptr, int prefmaxlen, out int entriesread, out int totalentries, out int resume_handle); [DllImport("Netapi32.dll ")] extern static int NetApiBufferFree(IntPtr Buffer);
应该是取自计算机管理 -> 系统工具 -> 本地用户和组 -> 用户
二、具体实例
1. 引入上述API接口
2. 封装成一个方法
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)] public struct USER_INFO_0 { public string Username; } public static List<string> GetSysUserNames() { List<string> users = new List<string>(); NetUserEnum(null, 0, 2, out IntPtr bufPtr, -1, out int entriesRead, out int totalEntries, out int resume); if (entriesRead > 0) { IntPtr iter = bufPtr; for (int i = 0; i < entriesRead; i ) { var user = (USER_INFO_0)Marshal.PtrToStructure(iter, typeof(USER_INFO_0)); iter = (IntPtr)((int)iter Marshal.SizeOf(typeof(USER_INFO_0))); users.Add(user.Username); } NetApiBufferFree(bufPtr); } return users; }
