Question

我刚开始学习C＃，我的问题可能听起来很愚蠢...

如何使用数据库中的数据填充我的viewmodel中的列表？

My Viewmodels：

  public class TransferSpecificClientsViewModel
{

    public string TransferFrom { get; set; }
    public string TransferTo { get; set; }
    public virtual ICollection<ClientsToTransfer> ClientsToTransferList { get; set; }

}

public class ClientsToTransfer
{
    public bool IsSelected { get; set; }
    public int ClientId { get; set; }
    public int UserId { get; set; }
    public string Name { get; set; }

}

在控制器中我可能需要这样的东西：

var  model = (from p in db.Clients
                 select new TransferSpecificClientsViewModel()
                 {
                     // And here I need to populate the ClientsToTransferList with data from db.Clients... I think it should probably be something like
                     //ClientsToTransferList.ClientId  = p.Id
                     //ClientsToTransferList.UserId = p.UserId
                     //ClientsToTransferList.Name = p.Name });

但对于我数据库中的每个客户端

我只是不知道如何让它发挥作用......而且不熟悉C＃我不知道如何正确地搜索我想要做的事情......

你真的很亲近。我将virtual ICollection<ClientsToTransfer>更改为List<ClientsToTransfer>并按照您的想法进行选择。

//...initialize TransferFrom and TransferTo properties of your view model
model.ClientsToTransferList = 
             (from p in db.Clients
             select new ClientsToTransfer()
             {
                 ClientId  = p.Id
                 UserId = p.UserId
                 Name = p.Name 
             }).ToList();
