備註

搜尋 name 會區分大小寫。

如果目前的 Type 代表建構的泛型型別，這個方法會傳回 Type ，並將 型別參數取代為適當的型別引數。

如果目前的 Type 代表泛型型別或泛型方法定義中的型別參數，這個方法會搜尋介面條件約束，以及繼承自類別或介面條件約束的任何介面。

注意

若為泛型介面，參數 name 是泛型名稱，結尾為輔色 (') 和類型參數數目。 這適用于泛型介面定義和建構的泛型介面。 例如，若要在 Visual Basic) 中尋找 (，或在 Visual Basic) 中尋找 IExample<T>IExample(Of T) (IExample(Of String) ，請搜尋 "IExample`1" 。 IExample<string>

如果目前的 Type 代表建構的泛型型別，這個方法會傳回 Type ，並將 型別參數取代為適當的型別引數。

如果目前的 Type 代表泛型型別或泛型方法定義中的型別參數，這個方法會搜尋介面條件約束，以及繼承自類別或介面條件約束的任何介面。
