C# 使用实体框架检索WebApi 2

我想要实现的是从数据库中检索所有数据，现在我知道我需要替换

单缺省

我能知道下面的方法叫什么吗？我不认为是林克

[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));
}

[路由（“api/{AuthCode}/LoadWorkers”）]
公共任务获取（字符串Authcode）
{
DateTime futureDate=新日期时间（）；
futureDate=DateTime.Now.AddDays（90）；
工人结果=新工人（）；
结果=KKDB.workers.SingleOrDefault（p=>p.WWPED x.WWPED尝试使用
。其中（x=>x.WWPED
[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));
}
