在寻找用户界定的操作者时,表述班应当更加准确?
sealed class Foo
{
// just the private static method!
private static int op_Implicit() { return 1; }
public static implicit operator int(Foo foo) { return 2; }
}
public class Program
{
private static void Main()
{
var param = Expression.Parameter(typeof(Foo), "x");
// IndexOutOfRangeException was unhandled!
var lambda = Expression.Lambda<Func<Foo, int>>(
Expression.Convert(param, typeof (int)), param);
}
}
还有可能界定静态的<代码>op_Explicit或op_Implicit方法,其中不止一个论点和表述类别接受这一方法为用户界定的操作者!
p.s. expression 靠<代码>BledFlags.NonPublic旗帜的树木,可以搜索用户类型中的操作者,但该系统无法直接看到。 核心数字,但也允许信号标本找到“看像”用户定义的操作员的私人方法。 但是,C#规则不允许你界定和使用非公共经营者! 我认为,表达方式应当相同......。
