使用web.config在自定義成員資格中設置minRequiredPasswordLength

Question

我在項目中有CustomMembership類，並在類中使用此代碼：

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

並在web.config中設置成員資格

<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>

並使用此代碼獲取minRequiredPasswordLength：

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

但是得到“ 0”！ 我想得到“ 6”。

Answer 1

如果從抽象的MembershipProvider類派生，則應重寫MembershipProvider.Initialize 。 config集合將包含所有配置屬性，您可以使用它們來設置屬性，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; }
}

如果您是從現有提供程序（例如SqlMembershipProvider派生的，則可以簡單地使用MinRequiredPasswordLength的基類實現。

嘗試：

MinRequiredPasswordLength.Text = @CustomMembership.MinRequiredPasswordLength
