如何在 ASP.NET Web API 中实现通过 id 获取？

Question

当我尝试实现 get by id SPI 服务时，我得到了所有记录，而不是 ASP.NET Core Web API 中的一个特定记录。

        [HttpGet("EmployeeId")]
        public ActionResult<Employeedatum> Getbyid(int EmployeeId)
        {
           if(EmployeeId <= 0)
            {
                return NotFound("not found");
            }
            Employeedatum employeedata = DbContext.Employeedatum.FirstOrDefault(s => s.empid == EmployeeId);
            if(employeedata == null)
            {
                return NotFound("notfound");
            }
            return Ok(employeedata);

This is my code.

试试这个作为 Lync 查询

Employeedatum employeedata = DbContext.Employeedatum.where(s => s.empid == EmployeeId).FirstOrDefault();
