代码实现

使用日志

readonly Logger logger = LogManager.GetCurrentClassLogger();

Win10 Flat风格

CredUI.CREDUI_INFO info = new CredUI.CREDUI_INFO();info.pszCaptionText = "登录大伽";info.pszMessageText = "欢迎使用大伽智能病理系统";info.cbSize = Marshal.SizeOf(info);uint pulAuthPackage = 0, ulInAuthBufferSize = 0, pulOutAuthBufferSize;IntPtr pvInAuthBuffer = IntPtr.Zero, ppvOutAuthBuffer = IntPtr.Zero, pAuthBuffer = IntPtr.Zero;bool isSave = false;int maxUnSize = 50, maxPwSize = 50, maxDomSize = 50;StringBuilder un = new StringBuilder(maxUnSize), pw = new StringBuilder(maxPwSize), dom = new StringBuilder(maxDomSize);var error = CredUI.CredUIPromptForWindowsCredentials(info, Win32Error.NO_ERROR, ref pulAuthPackage, pvInAuthBuffer, ulInAuthBufferSize, out ppvOutAuthBuffer, out pulOutAuthBufferSize, ref isSave, CredUI.WindowsCredentialsDialogOptions.CREDUIWIN_GENERIC);if (error == Win32Error.ERROR_CANCELLED){logger.Debug($"{error}");return;}if (error != Win32Error.ERROR_SUCCESS){logger.Debug($"{error}");return;}var flag = CredUI.CredUnPackAuthenticationBuffer(CredUI.CredPackFlags.CRED_PACK_GENERIC_CREDENTIALS, ppvOutAuthBuffer, (int)pulOutAuthBufferSize, un, ref maxUnSize, dom, ref maxDomSize, pw, ref maxPwSize);if (un.ToString().IsBlank()){logger.Debug($"用户名不能为空！");return;}if (pw.ToString().IsBlank()){logger.Debug($"密码不能为空！");return;}if (!flag){logger.Debug($"获取用户名及密码信息失败！");return;}logger.Debug($"用户名：{un} 密码：{pw}");

XP风格

CredUI.CREDUI_INFO info = new CredUI.CREDUI_INFO();info.pszCaptionText = "登录大伽";info.pszMessageText = "欢迎使用大伽智能病理系统";info.cbSize = Marshal.SizeOf(info);IntPtr Reserved = IntPtr.Zero;bool isSave = false;int maxUnSize = 50, maxPwSize = 50;StringBuilder un = new StringBuilder(maxUnSize), pw = new StringBuilder(maxPwSize);var error = CredUI.CredUIPromptForCredentials(info, "www.dakapath.com/dakapath", Reserved, Win32Error.NO_ERROR, un, 10, pw, 10, ref isSave, CredUI.CredentialsDialogOptions.CREDUI_FLAGS_DEFAULT);

总结

Win10风格的那个，取到的不是明文，是一个加密后的Pack，需要使用Windows自带的方法进行解密才可以拿到真实的用户名和密码，而XP风格的那个，是直接取到明文；

不想画登录界面的，对登录界面要求比较简单，又想自己的程序登录起来有点逼格的可以用Win10的那个(⊙o⊙)…；
