C# 基于两个类（视图模型和域模型）显示自定义实体

嗨，我正在做一个项目使用asp.NETMVC4.0，与实体框架和linq。。。 所以我有两门课。 客户类别：

namespace LicenciamentoMVC.Models
{
public class Cliente
{
    [Key]
    public int IDCliente { get; set; }

    public string Nome { get; set; }
    public string Morada { get; set; }
    public string CPostal { get; set; }
    public string Localidade { get; set; }
    public string Freguesia { get; set; }
    public string Conselho { get; set; }
    public string Distrito { get; set; }
    public string Pais { get; set; }
    public string Telefone { get; set; }
    public string Telemovel { get; set; }
    public string Fax { get; set; }
    public string Email { get; set; }
    public string Nif { get; set; }
    public string WWW { get; set; }
    public string Observacoes { get; set; }
    public int IDP { get; set; }
    public int IDU { get; set; }
    public DateTime TStamp { get; set; }
    public int Rem { get; set; }
    public String TipoCliente { get; set; }

}
public class ClienteModel
{
    private static Cliente entity;
    public static IQueryable<Cliente> GetListaClientes()
    {
        MvcApplication1Context db = new MvcApplication1Context();

        var customers = from c in db.Clientes
                        orderby c.IDCliente descending
                        where c.Rem==0
                        select c;

        return customers.AsQueryable<Cliente>();
    }
  }
}

假设我想从类Processo查看IDprocesso和DataInserido，从类Cliente查看Nome

我的数据库由两个表Clientes和Processos组成。 我的dbContent类：

public class MvcApplication1Context:DbContext
{
    public MvcApplication1Context()
        : base("name=MvcApplication1Context")
    {
    }

    //protected override void OnModelCreating(DbModelBuilder modelBuilder)
    //{
    //    modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
    //}
    public DbSet<Cliente> Clientes { get; set; }
    public DbSet<Processo> Processos { get; set; }
 }

这是可行的，但我想知道这是正确的方法还是有更好的方法

再次感谢，…

如果我理解正确的话，这些物体之间没有任何真正的联系。这完全取决于需要显示多少数据

如果要显示相关数据，可以使用razor在视图上执行此操作：

@foreach(var client in Model.Clientes)
{
 <h1>@client.Name</h1>
<ul>
<li>Model.Processo.FirstOrDefault(f=> f.IDCliente == client.IDCliente).DataInserido.toString("dd-MM-yyyy")</li>
<li>.... other properties...</li>
</ul>
}

@foreach（Model.Clientes中的var客户端）
{
@客户名称

Model.Processo.FirstOrDefault（f=>f.IDCliente==client.IDCliente）.DataInserido.toString（“dd-MM-yyyy”）
……其他财产

}

processo中的IDCliente与cliente中的IDCliente之间存在连接…由于存在冲突问题，我没有使用外键..我将代码更改为IDCliente。通过这种方式，您可以访问propertiesok，但现在问题与igniteui组件有关…该组件接收iqueryable…如果您的组件需要iqueryable，则是，您需要创建一个新的poco并返回该poco的一个新iqueryable。因此，如果我理解，我应该创建一个viewmodel，以接收将在视图中显示的值？？？

public class ProcessoClienteModel
{
    private static ProcessoCliente entity;
    public static IQueryable<ProcessoCliente> GetListaProcessos()
    {
        MvcApplication1Context db = new MvcApplication1Context();

        var processos = from p in db.Processos
                        from c in db.Clientes
                        orderby p.IDProcesso descending
                        where p.IDCliente == c.IDCliente

                        where p.Rem == 0
                        select new { p.processoID,p.DataInserido,c.Nome} as  IQueryable<ClienteModel>;
        return processos;


        return processos.AsQueryable<ProcessoCliente>();
    }

}

                          orderby p.IDProcesso descending
                         select new ProcessoCliente { IDProcesso = p.IDProcesso, NomeCliente = c.Nome, DataInserido = p.DataInserido});


        return processos.AsQueryable<ProcessoCliente>();
    }
