接口不匹配属性存取器

Question

我有一个简单的接口，我想用不同的访问器来实现它

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

我正在尝试在 class 上使用 Public 或 Protected Get 和内部集实现此功能；

编辑这个 class 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;}
}

无论用哪种方式实现我都报错

尝试次数：

public AuthorizedDbContext Context { get; internal set;}

ValidatorByState.Context is not public

protected AuthorizedDbContext Context { get; internal set;}

ValidatorByState.Context.set Accessor must be more restrictive than property,

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

Explicit implementation missing Accessor

如何使用内部集获取 public 方法？

Answer 1

接口成员必须是public。

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; }
}

Answer 2

我会创建一个 public 接口，它是只读的，并且是 setter methods/properties 的内部接口。必须显式实现内部接口：

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; 
    }
}
