我得到一个stackoverflowexception,我不知道为什么

Question

我制作了自定义用户控件,但在设置自定义属性时遇到问题.这是我遇到问题的代码,我不知道为什么我会收到堆栈溢出异常.任何帮助将非常感激.

displayList = new List<ItemDisplay>();
foreach (var item in InventoryData2.Items)
{
    ItemDisplay id = new ItemDisplay();
    id.Item = item;
    id.Name = item.Item.ItemNumber;
    id.Location = new System.Drawing.Point(0, displayList.Count * id.Height);
    displayList.Add(id);
}


public InventoryItem Item 
{
    get { return Item; }
    set { 
        Item = value;
        lblItemNumber.Text = Item.Item.ItemNumber;
        lblTitle.Text = Item.Item.Title;
        lblModel.Text = Item.Item.Model;
        lblPrice.Text = Item.Item.Price.ToString();
    }
}

Answer 1

此属性的getter将导致无限递归:

public InventoryItem Item { get { return Item; }

二传手也是如此:

set 
{ 
    Item = value;

你可能想要这样的东西:

private InventoryItem item;

public InventoryItem Item 
{
    get 
    { 
        return this.item; 
    }
    set 
    { 
        this.item = value;
        lblItemNumber.Text = value.Item.ItemNumber;
        lblTitle.Text = value.Item.Title;
        lblModel.Text = value.Item.Model;
        lblPrice.Text = value.Item.Price.ToString();
    }
}
