ASP.NET WebAPI HttpGet操作-查询字符串后模型为null

Question

MVC操作不会反序列化以下查询字符串。 动作正常，但动作中的searchModel得到空值。

编辑 ：简化模型

模型

public class EmployeeSearchModel
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

行动：

    [HttpGet]
    public List<Employee> SearchEmployee(EmployeeSearchModel searchModel)
    {
        List<Employee> employees = new List<Employee>();
        try
        {
            if (searchModel != null)
            {
                //some logic
            }
            else
            {
                //dirty feedback for testing - this is what the action returns
                employees.Add(new Employee { FirstName = "searchModel was null" });
            }
        }
        catch (Exception e) { WriteFileLog(_logPath, e.ToString()); }

        return employees;
    }

Answer 1

那是ASP.NET MVC还是Web API？ 从您从控制器操作而不是ActionResult返回员工列表的事实来看，我可以看到它是Web API。 如果是这样，您可以将[FromUri]属性应用于模型：

public List<Employee> SearchEmployee([FromUri]EmployeeSearchModel searchModel)
