绑定对象的DataGridView C＃ [英] Binding objects DataGridView C#

问题描述

我有一个DataGridView，而我想展现对象的列表。

的对象是这些：

 公共类实体
{
    公众诠释ID {搞定;组; }
}公共类旅游：实体
{
    公共服务服务{搞定;组; }
    公共市源{搞定;组; }
    众城命运{搞定;组; }
    公共十进制价格{搞定;组; }
}公共类服务：实体
{
    公共字符串名称{;组; }
}公共类城市：实体
{
    公共字符串名称{;组; } //最多50个字符
}
 

在我的表单绑定我的旅行对象像这样的列表：

 列表＆LT;旅游与GT;行进= logic.GetAllTravels（）;
DgvRecorridos.DataSource =旅行;
 

和我得到以下内容：

我想获得的服务，源城和命运，而不是城市。

的名称

先谢谢了。

解决方案

 列表＆LT;旅游与GT;行进= logic.GetAllTravels（）;
在旅行VAR _bind =从
            新选择
            {
                SERVICENAME = a.Service.Name，
                SOURCENAME = a.Source.Name，
                DestinyName = a.Destiny.Name，
                价格= a.Price
            };
DgvRecorridos.DataSource = _bind;
 

或

 列表＆LT;旅游与GT;行进= logic.GetAllTravels（）;
VAR _bind = travels.Select（A =＆gt;新建
            {
                SERVICENAME = a.Service.Name，
                SOURCENAME = a.Source.Name，
                DestinyName = a.Destiny.Name，
                价格= a.Price
            }）;
DgvRecorridos.DataSource = _bind;
 

i have a DataGridView and a list of objects that i would like to show.

The Objects are these:

public class Entity
{
    public int ID { get; set; }
}    

public class Travel: Entity
{
    public Service Service { get; set; }
    public City Source { get; set; }
    public City Destiny { get; set; }
    public decimal Price { get; set; }
}

public class Service: Entity
{
    public string Name { get; set; }
}

public class City: Entity
{
    public string Name { get; set; } // Max 50 chars
}

In my form i bind the list of of Travel Objects like this:

List<Travel> travels = logic.GetAllTravels();
DgvRecorridos.DataSource = travels;

And i get the following:

I would like to get the Name of the Service, Source City and Destiny City instead.

Thanks in advance.

解决方案

List<Travel> travels = logic.GetAllTravels();
var _bind = from a in travels
            select new
            {
                Servicename = a.Service.Name,
                SourceName = a.Source.Name,
                DestinyName = a.Destiny.Name,
                Price = a.Price
            };
DgvRecorridos.DataSource = _bind;

or

List<Travel> travels = logic.GetAllTravels();
var _bind = travels.Select(a => new 
            { 
                Servicename = a.Service.Name,
                SourceName = a.Source.Name,
                DestinyName = a.Destiny.Name,
                Price = a.Price
            });
DgvRecorridos.DataSource = _bind;
