WebApi 2使用實體框架檢索

Question

我想要實現的是從數據庫中檢索所有數據，到目前為止，我知道我需要替換

單一或默認

與其他東西，我可以知道下面叫什么方法嗎？ 我不認為是linq嗎？

[Route("api/{AuthCode}/LoadWorkers")]
public Task<HttpResponseMessage> GET(String Authcode)
{
    DateTime futureDate = new DateTime();
    futureDate = DateTime.Now.AddDays(90);
    worker result = new worker();
    result = KKDB.workers.SingleOrDefault(p => p.WWPED <= futureDate);
    return Task.FromResult(Request.CreateResponse<worker>(HttpStatusCode.OK, result));
}

解

[Route("api/{AuthCode}/LoadWorkers")]
public Task<HttpResponseMessage> GET(String Authcode)
{
  DateTime futureDate = new DateTime();
  futureDate = DateTime.Now.AddDays(90);
  var result = KKDB.workers.Where(x => x.WWPED <= futureDate);
  return Task.FromResult(Request.CreateResponse<IQueryable<worker>>HttpStatusCode.OK,result));
}

Answer 1

嘗試使用.Where(x => x.WWPED <= futureDate)可以獲取實體，然后可以將它們映射為所需格式以作為結果返回。 使用linq可能會更容易。
