如何在自定义MembershipProvider上调用Initialize？

我已经阅读了所有相关的问题,但由于某些原因我仍然无法得到正确的解决方案,有些事情不对我而言,但不确定是什么导致了它.

我创建了一个自定义成员资格提供程序,也将我的web.config更改为:

这是我的Initialize方法的代码:

public override void Initialize(string name, NameValueCollection config)
{
    if (config == null)
    { throw new ArgumentNullException("config"); }

    if (string.IsNullOrEmpty(name))
    { name = "MyMemberShipProvider"; }

    if (string.IsNullOrEmpty(config["description"]))
    {
        config.Remove("description");
        config.Add("description", "My Membership Provider");
    }

    base.Initialize(name, config);

    _applicationName = GetConfigValue(config["applicationName"], System.Web.Hosting.HostingEnvironment.ApplicationVirtualPath);
    _maxInvalidPasswordAttempts = Convert.ToInt32(GetConfigValue(config["maxInvalidPasswordAttempts"], "5"));
    _passwordAttemptWindow = Convert.ToInt32(GetConfigValue(config["passwordAttemptWindow"], "10"));
    _minRequiredNonAlphaNumericCharacters = Convert.ToInt32(GetConfigValue(config["minRequiredAlphaNumericCharacters"], "1"));
    _minRequiredPasswordLength = Convert.ToInt32(GetConfigValue(config["minRequiredPasswordLength"], "7"));
    _passwordStregthRegularExpression = Convert.ToString(GetConfigValue(config["passwordStrengthRegularExpression"], String.Empty));
    _enablePasswordReset = Convert.ToBoolean(GetConfigValue(config["enablePasswordReset"], "true"));
    _enablePasswordRetrieval = Convert.ToBoolean(GetConfigValue(config["enablePasswordRetrieval"], "true"));
    _requiredQuestionAndAnswer = Convert.ToBoolean(GetConfigValue(config["requiresQuestionAndAnswer"], "false"));
    _requiredUniqueEmail = Convert.ToBoolean(GetConfigValue(config["requiresUniqueEmail"], "true"));

    string temp_format = config["passwordFormat"];
    if (temp_format == null)
    {
        temp_format = "Hashed";
    }

    switch (temp_format)
    {
        case "Hashed":
            _passwordFormat = MembershipPasswordFormat.Hashed;
            break;
        case "Encrypted":
            _passwordFormat = MembershipPasswordFormat.Encrypted;
            break;
        case "Clear":
            _passwordFormat = MembershipPasswordFormat.Clear;
            break;
        default:
            throw new ProviderException("Password format not supported.");
    }

    ConnectionStringSettings _connectionStringSettings = ConfigurationManager.ConnectionStrings[config["connectionStringName"]];

    if (_connectionStringSettings == null || _connectionStringSettings.ConnectionString.Length == 0)
    {
        throw new ProviderException("Connection String Cannot Be Blank.");
    }

    _connectionString = _connectionStringSettings.ConnectionString;

    //Get Encryption and Decryption Key Information From the Information.

    System.Configuration.Configuration cfg = WebConfigurationManager.OpenWebConfiguration(System.Web.Hosting.HostingEnvironment.ApplicationVirtualPath);
    _machinekey = cfg.GetSection("system.web/machineKey") as MachineKeySection;

    if (_machinekey.ValidationKey.Contains("AutoGenerate"))
    {
        if (PasswordFormat != MembershipPasswordFormat.Clear)
        {
            throw new ProviderException("Hashed or Encrypted passwords are not supported with auto-generated keys.");
        }
    }

}

我注意到没有调用Initialize方法,我在这里阅读了问题并且人们说我不必手动调用,如果我正确连接了我的web.config,我不需要做什么,但我确实试图手动调用,但它在我试图转换NameValueCollection时给了我一个InvalidCastException.

谁能帮我？谢谢

要调用Initialize(),您需要以某种方式实例化自定义成员资格提供程序.像这样:

MyCustomMembershipProvider myProvider = (MyCustomMembershipProvider)Membership.Providers["NameOfMembershipProviderInConfig"];

现在,当您使用myProvider时,将调用自定义提供程序中的Initialize().
