问题描述
我已经阅读了所有相关问题,但是由于某种原因,我仍然无法获得正确的解决方案,这是我不正确的事情,但是不确定是什么原因造成的.
I have read through all the related questions, but I still unable to get the right solution for some reason, something is not right on my side, but not sure what's causing it.
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:
I have created a Custom Membership Provider, also changed my web.config to :
<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:
Here is the code for my Initialize method:
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,我在这里通读了问题,人们说我不必手动调用它,如果我正确连接了web.config的话,我不会必须做任何事情,但是我确实尝试手动调用它,但是当我尝试投射NameValueCollection时,它给了我InvalidCastException.
And I have noticed that the Initialize method was not called, I read through the questions here and the people were saying I do not have to call that manually, if I have wired up my web.config correctly, I don't have to do anything, but I do tried to call that manually, but it gave me an InvalidCastException when I was trying to cast NameValueCollection.
有人可以帮助我吗?谢谢
Can anyone help me? Thanks
推荐答案
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:
For Initialize() to be called, you will need to instantiate your custom membership provider a certain way. Like so:
MyCustomMembershipProvider myProvider = (MyCustomMembershipProvider)Membership.Providers["NameOfMembershipProviderInConfig"];
现在,当您使用myProvider时,将从您的自定义提供程序中调用Initialize().
Now when you use myProvider, Initialize() from your custom provider will be called.
