我得到这个code用户控件:
I got this code in a user control:
[DefaultValue(typeof(Color), "Red")]
public Color MyColor { get; set; }
如何修改 MyColor
来作为它的默认值?
How can I change MyColor
to be its default value?
这是非正式的,但你可以通过反射使用它,例如,发生在你的构造如下:
It is informal, but you can use it via reflection, for example, place in your constructor the following:
foreach (PropertyInfo p in this.GetType().GetProperties())
{
foreach (Attribute attr in p.GetCustomAttributes(true))
{
if (attr is DefaultValueAttribute)
{
DefaultValueAttribute dv = (DefaultValueAttribute)attr;
p.SetValue(this, dv.Value);
}
}
}
