      Catch e As Exception
         Console.WriteLine(("Exception : " + e.ToString()))
      End Try
   End Sub
End Class

備註

name的搜尋會區分大小寫。

如果目前的 Type 代表建構的泛型型別，這個方法會傳回 Type ，其型別參數會由適當的型別自變數所取代。

如果 電流 Type 代表一般型別或通用方法定義中的型別參數，該方法會搜尋介面約束以及從類別或介面約束繼承的任何介面。

Note

對於通用介面， name 參數是混亂的名稱，結尾帶有重音符號（'），以及型別參數的數量。 這對通用介面定義和構造化通用介面皆適用。 例如，要找到 IExample<T>（IExample(Of T) 在 Visual Basic 中）或 IExample<string>（IExample(Of String)在 Visual Basic中），搜尋 "IExample`1"。

備註

該 ignoreCase 參數僅適用於簡單的介面名稱，而非命名空間。 其中指定命名空間的部分 name 必須是正確的大小寫，否則介面將無法被找到。 例如，字串「System.icomparable」能 IComparable 找到介面，但字串「system.icomparable」找不到。

如果目前的 Type 代表建構的泛型型別，這個方法會傳回 Type ，其型別參數會由適當的型別自變數所取代。

如果 電流 Type 代表一般型別或通用方法定義中的型別參數，該方法會搜尋介面約束以及從類別或介面約束繼承的任何介面。

Note

對於通用介面， name 參數是混亂的名稱，結尾帶有重音符號（'），以及型別參數的數量。 這對通用介面定義和構造化通用介面皆適用。 例如，要找到 IExample<T>（IExample(Of T) 在 Visual Basic 中）或 IExample<string>（IExample(Of String)在 Visual Basic中），搜尋 "IExample`1"。
