static class を使う場合
var static_flg = BindingFlags.Static | BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic;
得たメソッドの返り値が Taskか
bool isAwaitable(MethodInfo m)
{
var rtype = m.ReturnType;
var ch = typeof(Task).ToString();
if (rtype.ToString().IndexOf(ch) == -1) return false;
return true;
}
