使用.net核心中的部分键在redis中获取数据

Question

我在我的redis服务器中有这些密钥和它们的数据：

AdminIpoChangeEntity:0
AdminIpoChangeEntity:1
AdminIpoChangeEntity:2
AdminIpoChangeEntity:3

我只想把AdminIpoChangeEntity传递给我的方法，我的方法应该返回四个记录。这是我的redis存储库：

 private IDatabase RedisDb => _connection.Value.GetDatabase();
    //

    private string Key(TEntity entity) => $"{typeof(TEntity).Name}:{entity.Id}";
    private string Key(string id) => $"{typeof(TEntity).Name}:{id}";

    public async Task<OperationResult> AddOrUpdateAsync(TEntity entity)
    {
            var val = System.Text.Json.JsonSerializer.Serialize(entity);
            var res = await RedisDb.StringSetAsync(Key(entity), val);

            return OperationResult<TEntity>.Succeed();
    }
   public async Task<OperationResult<TEntity>> GetByIdAsync(string id)
    {
            var value = await RedisDb.StringGetAsync(Key(id));
            if (value.HasValue)
            {
                var result = System.Text.Json.JsonSerializer.Deserialize<TEntity>(value.ToString());
                return OperationResult<TEntity>.Succeed(result);
            }
            return OperationResult<TEntity>.Succeed(null);

    }

我需要这个：

public async Task<OperationResult<IList<TEntity>>> GetAllAsync()
{

        var value = await RedisDb.StringGetAsync(Key(nameof(TEntity)));

        throw new NotImplementedException();

}

我的实体名是AdminIpoChangeEntity

我应该找到与我的值匹配的所有键，然后将它们传递到getstring以查找所有值，下面是我的最后代码：

public async Task<OperationResult<IList<TEntity>>> GetAllAsync()
{
    EndPoint endPoint = _connection.Value.GetEndPoints().First();
    RedisKey[] keys = _connection.Value.GetServer(endPoint).Keys(pattern: typeof(TEntity).Name+"*").ToArray();
    var value = await RedisDb.StringGetAsync(keys);
    if (value.Count()>0)
    {
      var result=  value.Select(d => System.Text.Json.JsonSerializer.Deserialize<TEntity>(d)).ToArray();
      //  var result = System.Text.Json.JsonSerializer.Deserialize<IList<TEntity>>(value.ToString());
        return OperationResult<IList<TEntity>>.Succeed(result);
    }
    return OperationResult<IList<TEntity>>.Succeed(null);

}
