我已经阅读了所有相关的问题,但由于某种原因我仍然无法得到正确的解决方案,我这边有些不对劲,但不确定是什么原因造成的。
我创建了一个自定义成员资格提供程序,还将我的 web.config 更改为:
<membership defaultProvider="MyMemberShipProvider">
<providers>
<clear />
<add name="MyMemberShipProvider"
type="MyNameSpace.MyMemberShipProvider"
connectionStringName="ApplicationServices"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="false"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="6"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
passwordStrengthRegularExpression=""
applicationName="MyApplication" />
</providers>
</membership>
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.");
}
}
}
而且我注意到没有调用 Initialize 方法,我通读了这里的问题,人们说我不必手动调用它,如果我正确连接了我的 web.config,我不必这样做任何东西,但我确实尝试手动调用它,但是当我尝试投射 NameValueCollection 时它给了我一个 InvalidCastException。
谁能帮我?谢谢
