多載

MakeArrayType(Int32)	傳回 Type 物件，代表由目前類型組成且為指定維度個數的陣列。
MakeArrayType()	傳回 Type 物件，代表由目前類型組成的一維陣列，其下限為零。

MakeArrayType(Int32)

來源:

TypeBuilder.cs

傳回 Type 物件，代表由目前類型組成且為指定維度個數的陣列。

C#

public override Type MakeArrayType(int rank);

參數

rank

Int32

陣列的維度數目。

傳回

Type

Type 物件，代表目前類型的一維陣列。

例外狀況

IndexOutOfRangeException

rank 不是有效的陣列維度。

範例

下列程式代碼範例會建立動態模組、名為 Sample的抽象類型，以及名為 TestMethod的抽象方法。 TestMethod ref採用 Visual Basic) 類型的Sample參數 (ByRef、型Sample別的指標，以及類型的Sample陣列。 它會傳回 類型的 Sample二維陣列。 此程式代碼範例會將動態模組儲存至磁碟，因此您可以使用 Ildasm.exe (IL 反組譯程式) 加以檢查。
