c# - 如何在 C# 中获取属性网格项名称、标签和值？

Question

我在 propertygrid 中定义项目。我的代码在这里:

[DisplayName("Title of book"), CategoryAttribute("Books")]
public string BookName{ get; set; }

使用此代码，我可以从 propertygrid 获取 Labele 和该项目的值(对于此示例:书名及其值(例如)学习 C# ):

private void button1_Click(object sender, EventArgs e)
{
    GridItem gi = propertyGrid1.SelectedGridItem;
    while (gi.Parent != null)
    {
        gi = gi.Parent;
    }
    foreach (GridItem item in gi.GridItems)
    {
        ParseGridItems(item); //recursive
    }
}

private void ParseGridItems(GridItem gi)
{
    if (gi.GridItemType == GridItemType.Category)
    {
        foreach (GridItem item in gi.GridItems)
        {
            ParseGridItems(item);
        }
    }
    textBox1.Text += "Lable : "+gi.Label + "\r\n";
    if(gi.Value != null)
        textBox1.Text += "Value : " + gi.Value.ToString() + "\r\n";
}

如何获取商品名称？对于此示例:BookName

使用GridItem.PropertyDescriptor属性:

var propertyName = propertyGrid1.SelectedGridItem.PropertyDescriptor.Name;
