我有自定义属性和使用这些属性的类。选择类对象时,这些属性用于Property Grid。目前,类和属性都在同一个程序集中。在属性中,我有一些Form对象。由于这些Form对象,我想将属性保存在单独的程序集中。然而,它导致循环引用。你能帮我解决这个问题吗?
样品:
我有业务对象,其属性可以在PropertyGridControl中显示:
public class Field
{
public Field()
{
}
private int _Type;
[CustomPropertyEditorMarker(typeof(RepositoryItemForFieldDataType))]
public int Type
{
get { return _Type; }
set
{
_Type = value;
}
}
}
[AttributeUsage(AttributeTargets.Property)]
public sealed class CustomPropertyEditorMarker : Attribute
{
public CustomPropertyEditorMarker(Type editorType)
{
EditorType = editorType;
}
public readonly Type EditorType;
}
public sealed class RepositoryItemForFieldDataType : RepositoryItemLookUpEdit
{
public RepositoryItemForFieldDataType()
{
// Populating LookupEdit details here
}
private void On_ButtonClick()
{
// Here initializing existing Form class and show it
}
}
When Field object is selected, PropertGridControl analyze selected object and checking which property has above Attribute. If yes, then initialize it.
private void SelectObject(object obj)
{
this.Rows.Clear();
this.DefaultEditors.Clear();
this.RepositoryItems.Clear();
if ((this.LastSelectedObject as ApplicationDomainItemBase) != null)
{
(this.LastSelectedObject as ApplicationDomainItemBase).IsSelected = false;
};
this.SelectedObject = null;
this.SelectedObject = obj;
if (!(this.SelectedObject is ConfigurationObjectManagerBase))
{
foreach (var propInfo in this.SelectedObject.GetType().GetProperties())
{
object[] objFieldAtts = propInfo.GetCustomAttributes(typeof(CustomPropertyEditorMarker), true);
if (objFieldAtts != null && objFieldAtts.Length > 0)
{
if (this.GetRowByFieldName(propInfo.Name) != null)
{
RepositoryItem repItem = Activator.CreateInstance(((CustomPropertyEditorMarker)objFieldAtts[0]).EditorType) as RepositoryItem;
this.GetRowByFieldName(propInfo.Name).Properties.RowEdit = repItem;
};
};
};
};
this.LastSelectedObject = obj;
}
目前,业务对象类和属性都在同一个程序集中,需要将它们分开。但是我不能,因为业务对象属性是用属性名称装饰的,需要添加引用。由于Attribute类引用了业务对象类,因此无法添加引用。希望清楚。感谢。

如果没有看到引起问题的业务对象引用,一般答案如下:
将您的业务对象基于接口,这些接口将在您想要移动属性的同一程序集中声明,或者另一个" base"部件。然后通过接口引用属性中的业务对象。
