接口不匹配属性访问器

Question

我有一个简单的接口，我想用不同的访问器来实现

public interface IValidatorByState : IValidator
{
    AuthorizedDbContext Context { get; set; }
}

我正在尝试在具有公共或受保护获取和内部集的类上实现这一点；

Edit这个类是暴露给用户的，他们应该只能检索上下文。

public class ValidatorByState<TEntity> : AbstractValidator<TEntity>, IValidatorByState
{
    public AuthorizedDbContext Context { get; internal set;}
}

不管用哪种方式实现都报错

尝试：

public AuthorizedDbContext Context { get; internal set;}

ValidatorByState.Context 不公开

protected AuthorizedDbContext Context { get; internal set;}

ValidatorByState.Context.set 访问器必须比属性更严格，

AuthorizedDbContext _context;
public AuthorizedDbContext IValidatorByState.Context => this._context;
public AuthorizedDbContext IValidatorByState.Context {
    set { this._context = value; }
}

为此，我在两个陈述中都遇到了错误

显式实现缺少访问器

我怎样才能有一个带有内部集的公共 get 方法？

Answer 1

我将创建一个带有 setter 方法/属性的只读和内部接口的公共接口。内部接口必须显式实现：

public interface IValidatorByStateReadOnly 
{
    AuthorizedDbContext Context { get; }
}  

internal interface IValidatorByState : IValidatorByStateReadOnly
{
    new AuthorizedDbContext Context { get; set; }
}

public class ValidatorByState<TEntity> : IValidatorByState
{
    private AuthorizedDbContext _context;

    public AuthorizedDbContext Context => _context;

    AuthorizedDbContext IValidatorByState.Context 
    {
        get => _context;
        set => _context = value; 
    }
}

Answer 2

接口成员必须是公开的。

关于：

public interface IValidatorByStateReader
{
    AuthorizedDbContext Context { get; }
}

internal interface IValidatorByStateWriter
{
    AuthorizedDbContext Context { set; }
}

public class ValidatorByState<TEntity> : IValidatorByStateReader, IValidatorByStateWriter
{
    private AuthorizedDbContext _context;
    AuthorizedDbContext IValidatorByStateReader.Context => this._context;
    AuthorizedDbContext IValidatorByStateWriter.Context { set => this._context = value; }
}
