建立包含小整數的一系列區段。

多載

CreateSection(Int16)	建立包含小整數之一系列區段中的第一個 BitVector32.Section。
CreateSection(Int16, BitVector32+Section)	在包含小整數的一系列區段中，建立新 BitVector32.Section 於指定的 BitVector32.Section 之後。

範例

下列程式代碼範例使用 BitVector32 做為區段的集合。

建立包含小整數之一系列區段中的第一個 BitVector32.Section。

public:
 static System::Collections::Specialized::BitVector32::Section CreateSection(short maxValue);

public static System.Collections.Specialized.BitVector32.Section CreateSection (short maxValue);

static member CreateSection : int16 -> System.Collections.Specialized.BitVector32.Section

Public Shared Function CreateSection (maxValue As Short) As BitVector32.Section

參數

maxValue: Int16

16 位元帶正負號的整數，會指定新 BitVector32.Section 的最大值。

傳回

BitVector32.Section

BitVector32.Section，可以存放零到 maxValue 的數字。

例外狀況

ArgumentException

maxValue 小於 1。

備註

BitVector32.Section是的BitVector32視窗，由最小數目的連續位組成，可包含中指定的CreateSection最大值。例如，最大值為1的區段只包含一個位，而最大值為5的區段則由三位組成。您可以建立最大值為 1 的， BitVector32.Section 以做為布爾值，因此可讓您將整數和布爾值儲存在相同的 BitVector32中。

如果區段已存在於中 BitVector32，這些區段仍可存取;不過，重迭區段可能會導致非預期的結果。

這個方法是 O (1) 作業。

參數

maxValue: Int16

16 位元帶正負號的整數，會指定新 BitVector32.Section 的最大值。

previous: BitVector32.Section

BitVector32.Section 中的前一個 BitVector32。

傳回

BitVector32.Section

BitVector32.Section，可以存放零到 maxValue 的數字。

例外狀況

maxValue 小於 1。

InvalidOperationException

previous 包含 BitVector32 中的最後位元。

maxValue 大於最大值，該最大值可以由 previous 之後的位元數表示。

備註

如果區段已存在於 previous 之後 BitVector32，這些區段仍可存取;不過，重迭區段可能會導致非預期的結果。
