c#记一次反射调用泛型方法运用

var typeList = Assembly.GetEntryAssembly().GetTypes();
foreach (var itema in typeList)
{
//筛选方法
var methodList = itema.GetMethods(BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public).Where(w => w.CustomAttributes.Any(a => a.AttributeType == typeof(SubscriberAttribute))).ToList();
if(methodList == null || methodList.Count<=0)
{
continue;
}

//遍历方法
foreach (var itemb in methodList)
{
//方法第一个参数
var param = itemb.GetParameters().First();
//参数类型
var paramType = param.ParameterType;

//action泛型对象
var genericAction = typeof(Action<>);
//指定泛型类型
var actionType = genericAction.MakeGenericType(new[] { paramType });
//为action指定实现
var actualMethod = Delegate.CreateDelegate(actionType, null,itemb);

Task.Factory.StartNew(() => {
//获取对象方法
var subscriber = _subscriberBus.GetType().GetMethod("Subscriber");
//为泛型方法指定泛型类型
var method = subscriber.MakeGenericMethod(paramType);
//执行方法
method.Invoke(_subscriberBus,new object[] { actualMethod });
});
}
