注意

値型の配列の要素に null を割り当てるために SetValue を使用する場合、要素のすべてのフィールドが0に初期化されます。If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. 要素の値は null 参照ではなく、null 参照を検索することによって見つけることができません。The value of the element is not a null reference, and cannot be found by searching for a null reference.

例外

現在の Array に設定されている次元が 3 つではありません。The current Array does not have exactly three dimensions.

value は現在の Arrayの要素の型にキャストできません。value cannot be cast to the element type of the current Array.

index1index2 または index3 が、現在の Array の対応する次元の正しいインデックスの範囲に含まれていません。index1 or index2 or index3 is outside the range of valid indexes for the corresponding dimension of the current Array.

次のコード例は、1次元配列または多次元配列で特定の値を設定して取得する方法を示しています。The following code example demonstrates how to set and get a specific value in a one-dimensional or multidimensional array.

GetLowerBound および GetUpperBound メソッドは、いずれかのインデックスが範囲外であるかどうかを判断できます。The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

このメソッドは、O(1) 操作です。This method is an O(1) operation.

注意

値型の配列の要素に null を割り当てるために SetValue を使用する場合、要素のすべてのフィールドが0に初期化されます。If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. 要素の値は null 参照ではなく、null 参照を検索することによって見つけることができません。The value of the element is not a null reference, and cannot be found by searching for a null reference.
