我正在编写我的第一个MVC应用程序，并且正在创建一个新的MembershipProvider但是遇到了一些编译错误，这些错误在此过程中完全错误。这是我的代码：
public class ProfileProvider : MembershipProvider
{
protected NameValueCollection Config = null;
protected new String Name = null;
protected String _PasswordStrengthRegularExpression = "";
protected int _MinRequiredNonAlphanumericCharacters = 0;
protected int _MinRequiredPasswordLength = 0;
protected String _PasswordFormat = "";
protected Boolean _RequiresUniqueEmail = false;
protected int _PasswordAttemptWindow = 0;
protected int _MaxInvalidPasswordAttempts = 0;
protected String _ApplicationName = "";
protected Boolean _RequiresQuestionAndAnswer = false;
protected Boolean _EnabledPasswordReset = false;
protected Boolean _EnablePasswordRetrieval = false;
protected override String PasswordStrengthRegularExpression
{
get
{
return this._PasswordStrengthRegularExpression;
}
set
{
this._PasswordStrengthRegularExpression = value;
}
}
public override int MinRequiredNonAlphanumericCharacters
{
get
{
return this._MinRequiredNonAlphanumericCharacters;
}
set
{
this._MinRequiredNonAlphanumericCharacters = value;
}
}
public override int MinRequiredPasswordLength
{
get
{
return _MinRequiredPasswordLength;
}
set
{
this._MinRequiredPasswordLength = value;
}
}
public override String PasswordFormat
{
get
{
return this._PasswordFormat;
}
set
{
this._PasswordFormat = value;
}
}
public override Boolean RequiresUniqueEmail
{
get
{
return _RequiresUniqueEmail;
}
set
{
this._RequiresUniqueEmail = value;
}
}
public override int PasswordAttemptWindow
{
get
{
return this._PasswordAttemptWindow;
}
set
{
this._PasswordAttemptWindow = value;
}
}
public override int MaxInvalidPasswordAttempts
{
get
{
return this._MaxInvalidPasswordAttempts;
}
set
{
this._MaxInvalidPasswordAttempts = value;
}
}
public override String ApplicationName
{
get
{
return this._ApplicationName;
}
set
{
this._ApplicationName = value;
}
}
public override Boolean RequiresQuestionAndAnswer
{
get
{
return this._RequiresQuestionAndAnswer;
}
set
{
this._RequiresQuestionAndAnswer = value;
}
}
public override Boolean EnablePasswordReset
{
get
{
return this._EnabledPasswordReset;
}
set
{
this._EnabledPasswordReset = value;
}
}
public override Boolean EnablePasswordRetrieval
{
get
{
return this._EnablePasswordRetrieval;
}
set
{
this._EnablePasswordRetrieval = value;
}
}
这是我的编译错误：

我已经接受了几次传递，我尝试使用'new'关键字而不是覆盖，似乎没有任何效果。
