Question

我在项目中有 CustomMembership 类，并在课堂上使用此代码：

private static int _MinRequiredPasswordLength;
public static int MinRequiredPasswordLength
    {
        set { _MinRequiredPasswordLength = value; }
        get { return _MinRequiredPasswordLength; }
    }

并在web.config中设置成员资格

<membership defaultProvider="CustomMembership">
  <providers>
    <clear />
    <add name="CustomMembership" type="Project1.Code.CustomMembership, Project1, Version=1.0.0.0, Culture=neutral" connectionStringName="PConn" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
  </providers>
</membership>

并使用此代码获取minRequiredPasswordLength：

MinRequiredPasswordLength.Text = CMembership.MinRequiredPasswordLength.ToString();

但得到'0'！我想要'6'。

Answer 1

如果您是从抽象MembershipProvider类派生的，则应覆盖MembershipProvider.Initialize。 config集合将包含所有配置属性，您可以使用它们来设置属性，包括MinRequiredPasswordLength：

private int _minRequiredPasswordLength;

public override void Initialize(string name, NameValueCollection config)
{
    _minRequiredPasswordLength = // get it from config["minRequiredPasswordLength"], with validation and conversion to int.
}

public override MinRequiredPasswordLength
{
    get { return _minRequiredPasswordLength; }
}

如果您来自现有提供商，例如SqlMembershipProvider，然后您可以简单地使用MinRequiredPasswordLength的基类实现。

尝试：

MinRequiredPasswordLength.Text = @CustomMembership.MinRequiredPasswordLength

使用web.config在自定义成员资格中设置minRequiredPasswordLength
