来自实体 c# 的 Post(HTTP) 值的正确方式

Question

所以，我是实体的新手。我正在尝试发布一些值，但我无法在另一个模型类中获取一个模型类的值。 如果我正在考虑做错什么，我感谢任何有关正确方法的帮助。

模型类 1（结果）

public partial class resultados
{
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
    public resultados()
    {
        this.respLysholm = new HashSet<respLysholm>();
    }

    public int idResult { get; set; }
    public int perfilPac_idPac { get; set; }
    public int resultado { get; set; }
    public int id_questionario { get; set; }
    public System.DateTime dtRegistro { get; set; }
    //public respLysholm respostasLysholm { get; set; }

    public virtual perfilPac perfilPac { get; set; }
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
    public virtual ICollection<respLysholm> respLysholm { get; set; }
} 

模型类 2 (respLysholm)：

public partial class respLysholm
{
    public int idPac { get; set; }
    public int resultados_idResult { get; set; }
    public int questao1 { get; set; }
    public int questao2 { get; set; }
    public int questao3 { get; set; }
    public int questao4 { get; set; }
    public int questao5 { get; set; }
    public int questao6 { get; set; }
    public int questao7 { get; set; }
    public int questao8 { get; set; }
    public System.DateTime dtRegistro { get; set; }

}

在我的控制器中，我收到一个值为“resultados”且值为“respLysholm”的对象，它是“resultados”类中的类。 我需要将“respLysholm”的值发送到数据库。现在，只有“resultados”值正在运行。

[HttpPost]
[ResponseType(typeof(resultados))]
public async Task<IHttpActionResult> Postresultados([FromBody]resultados Resultados)
{

    if (!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    }


    db.resultados.Add(Resultados);
    await db.SaveChangesAsync();

    respLysholm respostas = new respLysholm
    {
        idPac = Resultados.perfilPac_idPac,
        resultados_idResult = Resultados.idResult

    };
    \\this code doesnt work but is what i mean that i need.
    \\db.respLysholm.Add(Resultados.respLysholm);
    \\await db.SaveChangesAsync();

}

Post 的正文...我想获取“respostasLysholm”的所有值。

{"idResult":0,"perfilPac_idPac":1,"resultado":14,"id_questionario":1,"dtRegistro":"2017-05-23T23:28:24.916866-03:00",
"respostasLysholm":{"idPac":1,"resultados_idResult":0 ,"questao1":3}}

Answer 1

您的代码很难阅读，因为您没有遵循任何 C# 或 .NET 约定。你所拥有的是一对多的关系。以下是如何以一对多的关系将项目添加到 db。在这个例子中，我们有一个可以有很多学生的班级：

var science = new Class();
science.Name = "Sci-101";

science.Students.Add(new Student { Name = "Tom" });
science.Students.Add(new Student { Name = "Jerry" });

using (var dbCtx = new SchoolDBEntities())
{
    // Add the class
    dbCtx.Classes.Add(science);

    // Save whole entity graph to the database.
    // You do not need to save the students separately since they are part
    // of the class. We have already added them to the class so saving the 
    // class will save the students added to the class as well.
    dbCtx.SaveChanges();
}
