我想在伪代码中动态设置自定义事件处理程序的列表,如下所示:
FieldInfo[] fieldInfos = this.GetType().GetFields(
BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.DeclaredOnly);
foreach (FieldInfo fieldInfo in fieldInfos)
{
if this.fieldInfo.GetType() = TypeOf(CustomEventHandler<this.fieldInfo.Name>) {
this.fieldInfo.Name += new CustomEventHandler<this.fieldInfo.Name>(OnChange<this.fieldInfo.Name>);
}
}
我找不到正确的语法吗?
最佳答案
用GetEvents代替GetFields怎么样?
var t = something.GetType();
var eventInfos = t.GetEvents();
foreach (var info in eventInfos)
{
if (info.EventHandlerType == TypeOf(CustomEventHandler<this.fieldInfo.Name>)
info.AddEventHandler(...);
}
我不太确定类型比较,但是话又说回来,
fieldInfo.Name
不能在这样的泛型中使用。
