c# - 无法验证用户名和密码

Question

我需要验证用户输入对于当前 session 窗口是否正确。因此我使用下面的代码:

private void LoginUser(string username, string password)
{
    bool isCredentialValid = false;

    using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
    {
        isCredentialValid = context.ValidateCredentials(username, password);
    }
    if (isCredentialValid)
    {
        //
    }
    else
    {
        //
    }
}

我总是错误的问题ValidateCredentials结果。

来自 MSDN http://msdn.microsoft.com/en-us/library/bb154889.aspx

The ValidateCredentials method binds to the server specified in the constructor. If the username and password parameters are null, the credentials specified in the constructor are validated. If no credential were specified in the constructor, and the username and password parameters are null, this method validates the default credentials for the current principal.

在 PrincipalContext 构造函数中，您还可以指定要检查的凭据。

 using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, domain, 
                   container, ContextOptions.SimpleBind, username, password))
{
    return pc.ValidateCredentials(domain + @"\" + username, password,
                               ContextOptions.SimpleBind);
}

试试这个。
