初學c#
class FactoryInfo{
private string _factoryId;
private string _factoryName;
private DateTime _editDateTimes;
private AreaInfo _areaId;
}
其中AreaInfo 是另外一個類，現在在在
FactoryInfo a = new FactoryInfo();
a.factoryName = "hello";
a.areaId = (怎麼把值取出來？)

最好使用属性
public AreaInfo AreaId
{
get
{
return _areaID;
}
}

[hegang888888888]

a.areaId = AreaInfo

[hegang888888888]

a.areaId =new AreaInfo

我有屬性
private string _factoryId;
private string _factoryName;
private DateTime _editDateTimes;
private AreaInfo _areaId;
/// <summary>
/// 沒有參數的工廠類構造函數
/// </summary>
public FactoryInfo()
{ }
/// <summary>
/// 有參數的工廠類構造函數
/// </summary>
/// <param name="factoryId"></param>
/// <param name="factoryName"></param>
/// <param name="editDateTimes"></param>
/// <param name="areaId"></param>
public FactoryInfo(string factoryId,string factoryName,DateTime editDateTimes,AreaInfo areaId)
{
_factoryId = factoryId;
_factoryName = factoryName;
_editDateTimes = editDateTimes;
_areaId = areaId;
}
/// <summary>
/// 地區編號
/// </summary>
public AreaInfo AreaId
{
get { return _areaId; }
set { _areaId = value; }
}
/// <summary>
/// 編輯日期
/// </summary>
public DateTime EditDateTimes
{
get { return _editDateTimes; }
set { _editDateTimes = value; }
}
/// <summary>
/// 工廠名稱
/// </summary>
public string FactoryName
{
get { return _factoryName; }
set { _factoryName = value; }
}
/// <summary>
/// 工廠編號
/// </summary>
public string FactoryId
{
get { return _factoryId; }
set { _factoryId = value; }
}

class FactoryInfo{
private string _factoryId;
private string _factoryName;
private DateTime _editDateTimes;
private AreaInfo _areaId;
}
仔细一看，怎么全是私有。。。。

哦，Ｉ　ＳＥＥ

FactoryInfo a = new FactoryInfo();
a.factoryName = "hello";
a.areaId = new AreaInfo(参数列表);
或者
a.areaId = AreaInfo类型变量
