The return type and parameter types of a delegate type must be at least as accessible as the delegate type itself. 委托類(lèi)型的返回類(lèi)型和參數類(lèi)型必須至少與委托類(lèi)型本身具有同樣的可訪(fǎng)問(wèn)性。
When a generic method is called without specifying type arguments, a type inference process attempts to infer type arguments for the call. 當不使用特定類(lèi)型的參數調用一個(gè)泛型函數時(shí)，類(lèi)型推斷會(huì )嘗試為此次調用推斷參數類(lèi)型。
