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

Question

i have CustomMembership class in project and use this code in class:

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

and set membership in web.config

<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>

and use this code for get minRequiredPasswordLength:

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

but get '0'! I want get '6'.

Answer 1

If you've derived from the abstract MembershipProvider class, you should override MembershipProvider.Initialize . The config collection will contain all the configuration attributes, and you can use them to set your properties including 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; }
}

If you've derived from an existing provider, eg SqlMembershipProvider , then you can simply use the base class implementation of MinRequiredPasswordLength .

尝试：

MinRequiredPasswordLength.Text = @CustomMembership.MinRequiredPasswordLength
