C# 考证账号密码的办法类

媒介

一样平常C#开辟过程当中伴侣们大要会碰到需求考证账号密码的操作，自己经由过程屡次考证（踩坑无数），终究找到了一个借算数比力靠谱的办法，如今总结分享给各人，年夜神们假如有更好的办法请正在再起区报告我哦！话未几道间接上代码

2.类

考证账号类：

[DllImport("Advapi32.dll", EntryPoint = "CredReadW", CharSet = CharSet.Unicode, SetLastError = true)]
//读与根据疑息
static extern bool CredRead(string target, CRED_TYPE type, int reservedFlag, out IntPtr CredentialPtr);
[DllImport("Advapi32.dll", EntryPoint = "CredWriteW", CharSet = CharSet.Unicode, SetLastError = true)]
//增长根据
static extern bool CredWrite([In] ref NativeCredential userCredential, [In] UInt32 flags);
[DllImport("Advapi32.dll", EntryPoint = "CredFree", SetLastError = true)]
static extern bool CredFree([In] IntPtr cred);
[DllImport("Advapi32.dll", EntryPoint = "CredDeleteW", CharSet = CharSet.Unicode)]
//删除根据
static extern bool CredDelete(string target, CRED_TYPE type, int flags);
[DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern bool CredEnumerate(string filter, uint flag, out uint count, out IntPtr pCredentials);
//登岸考证
[DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool LogonUser(string username, string domain,
string password, LogonType logonType,
LogonProvider logonProvider,
out IntPtr userToken);
[DllImport("Advapi32.DLL")]
static extern bool ImpersonateLoggedOnUser(IntPtr hToken);

3.留意事项

Interactive =2 当地交互登录。最多见的登录方法。
Network=3收集登录 - 最多见的是会见收集同享文件夹或挨印机。IIS的认证也是Type 3
Batch=4 谋划使命
Service=5 效劳
某些效劳是用一个域帐号去运转的，呈现Failure常睹的状况是办理员变动了域帐号密码，可是遗忘重设Service中的帐号密码。
Unlock=7 解除屏幕锁定
很多公司皆有如许的宁静设置：当用户分开屏幕一段工夫后，屏保法式会锁定计较机屏幕。解开屏幕锁定需求键进用户名战密码。此时发生的日记范例便是Type 7
NetworkCleartext=8 收集明文登录 – 凡是发作正在IIS 的 ASP登录。没有保举
NewCredentials=9 新身份登录 – 凡是发作正在RunAS方法运转某法式时的登录考证。
RemoteInteractive=10 长途登录 – 好比Terminal service大概RDP方法。可是Windows 2000是出有Type10的，用Type 2。WindowsXP/2003起有Type 10
CachedInteractive=11 缓存登录：
