備註

不同于大部分類別, Array 請提供 CreateInstance 方法,而不是公用建構函式,以允許晚期繫結存取。

參考型別專案會初始化為 null 。 實值型別專案會初始化為零。

這個方法是 O (n) 作業,其中 nlength

在 F# 中,通常會改用 Array.zeroCreate 函式。

備註

不同于大部分類別, Array 請提供 CreateInstance 方法,而不是公用建構函式,以允許晚期繫結存取。

陣列中的 lengths 專案數目必須等於新 Array 中的維度數目。 陣列的每個元素 lengths 都必須在新的 Array 中指定對應維度的長度。

參考型別專案會初始化為 null 。 實值型別專案會初始化為零。

這個方法是 O (n) 作業,其中 n 是 中 lengths 所有值的乘積。

適用於

CreateInstance(Type, Int64[])

來源:
Array.cs
來源:

來源:
Array.cs

建立指定 Type 和維度長度的多維 Array (具有以零為起始的索引)。 維度長度是在 64 位元整數的陣列中指定的。

public:
 static Array ^ CreateInstance(Type ^ elementType, ... cli::array <long> ^ lengths);
public static Array CreateInstance (Type elementType, params long[] lengths);
static member CreateInstance : Type * int64[] -> Array
Public Shared Function CreateInstance (elementType As Type, ParamArray lengths As Long()) As Array

參數

elementType
Type

要建立之 ArrayType

lengths
Int64[]

64 位元整數的陣列,代表要建立的 Array 的每個維度大小。 陣列中的每個整數都必須介於零和 Int32.MaxValue之間,包含。

傳回

指定之 Type 的新多維 Array,且每個維度具有指定的長度,並使用以零為起始的索引。

例外狀況

elementTypenull

-或-

lengthsnull

elementType 不是有效的 Type

-或-

lengths 陣列包含少於一個項目。

不支援 elementType。 例如,Void 不受支援。

-或-

elementType 是開放式泛型型別。

中的任何 lengths 值小於零或大於 Int32.MaxValue

備註

不同于大部分類別,請 Array 提供 CreateInstance 方法,而不是公用建構函式,以允許晚期繫結存取。

lengthslowerBounds 陣列必須具有相同的元素數目。 陣列中的 lengths 專案數目必須等於新 Array 中的維度數目。

陣列的每個元素 lengths 都必須在新的 Array 中指定對應維度的長度。

陣列的每個元素 lowerBounds 都必須在新的 Array 中指定對應維度的下限。 一般而言,.NET 類別庫和許多程式設計語言不會處理非零的下限。

參考型別專案會初始化為 null 。 實值型別專案會初始化為零。

這個方法是 O (n) 作業,其中 n 是 中 lengths 所有值的乘積。

注意

並非所有語言都支援具有非零下限的陣列,因此您可能無法將非零的 Array 實例轉換成語言的陣列類型。 例如,您無法將下限為 6 的 1 維整數陣列轉換成 C# 的類型 int[] 。 這會導致 InvalidCastException 執行時間期間出現「無法將類型為 'System.Int32[*]' 的物件轉換成類型 'System.Int32[]'」的訊息,其中星號 (*) 表示非零起始的索引。 不過,您可以將任何 CreateInstance(Type, Int32[], Int32[]) 使用 建立之順位的以零起始的陣列轉換成語言的陣列。 例如,您可以將以這個方法建立的 2D 零起始整數陣列轉換成 C# 的類型 int[,]

備註

不同于大部分類別,請 Array 提供 CreateInstance 方法,而不是公用建構函式,以允許晚期繫結存取。

參考型別專案會初始化為 null 。 實值型別專案會初始化為零。

這個方法是 O (n) 作業,其中 n 是 、 length2length3 的乘積 length1

在 F# 中,可以改用 Array3D.zeroCreate 函式。
