示例

// This method validates users. It allows two users, test1 and test2

public override void Validate(string userName, string password)
{
    if (null == userName || null == password)
    {
        throw new ArgumentNullException();
    }

    if (!(userName == "test1" && password == "1tset") && !(userName == "test2" && password == "2tset"))

' This method validates users. It allows two users, test1 and test2 
' with passwords 1tset and 2tset respectively.
' This code is for illustration purposes only and 
' MUST NOT be used in a production environment because it is NOT secure.	
Public Overrides Sub Validate(ByVal userName As String, ByVal password As String)
    If Nothing = userName OrElse Nothing = password Then
        Throw New ArgumentNullException()
    End If

    If Not (userName = "test1" AndAlso password = "1tset") AndAlso Not (userName = "test2" AndAlso password = "2tset") Then

注解

重写 Validate 方法以指定如何验证用户名和密码。 如果用户名和密码没有通过验证，则引发 SecurityTokenValidationException。
