A diferencia de la mayoría de las clases, Array proporciona el CreateInstance método, en lugar de los constructores públicos, para permitir el acceso enlazado en tiempo de ejecución.Unlike most classes, Array provides the CreateInstance method, instead of public constructors, to allow for late bound access.
Los elementos de tipo de referencia se inicializan en null .Reference-type elements are initialized to null. Los elementos de tipo de valor se inicializan en cero.Value-type elements are initialized to zero.
Este método es una operación O ( n ), donde n es length .This method is an O(n) operation, where n is length.

Las lengths lowerBounds matrices y deben tener el mismo número de elementos.The lengths and lowerBounds arrays must have the same number of elements. El número de elementos de la lengths matriz debe ser igual al número de dimensiones del nuevo Array .The number of elements in the lengths array must equal the number of dimensions in the new Array.
Cada elemento de la lengths matriz debe especificar la longitud de la dimensión correspondiente en el nuevo Array .Each element of the lengths array must specify the length of the corresponding dimension in the new Array.
Cada elemento de la lowerBounds matriz debe especificar el límite inferior de la dimensión correspondiente en el nuevo Array .Each element of the lowerBounds array must specify the lower bound of the corresponding dimension in the new Array. Por lo general, la biblioteca de clases .NET y muchos lenguajes de programación no controlan los límites inferiores distintos de cero.Generally, the .NET class library and many programming languages do not handle non-zero lower bounds.
Los elementos de tipo de referencia se inicializan en null .Reference-type elements are initialized to null. Los elementos de tipo de valor se inicializan en cero.Value-type elements are initialized to zero.
Este método es una operación O ( n ), donde n es el producto de todos los valores de lengths .This method is an O(n) operation, where n is the product of all values in lengths.
Nota
No todos los lenguajes admiten matrices con límite inferior distinto de cero y, por lo tanto, es posible que no pueda convertir instancias de distinto de cero basadas Array en el tipo de matriz del lenguaje.Not all languages support arrays with non-zero lower bounds, and therefore you may not be able to cast instances of non-zero based Array to the language's array type. Por ejemplo, no se puede convertir una matriz de enteros de una dimensión con el límite inferior 6 al tipo de C# int[] .For example, you cannot cast a 1-dimensional integer array with the lower bound 6 to C#'s int[] type. Esto se produce InvalidCastException durante el tiempo de ejecución con el mensaje "no se puede convertir el objeto de tipo ' System. Int32 [ * ] ' al tipo ' System. Int32 [] '.", donde el asterisco ( * ) significa un índice basado en cero.This results in InvalidCastException during runtime with the message "Unable to cast object of type 'System.Int32[*]' to type 'System.Int32[]'.", where the asterisk (*) means non-zero based index. Sin embargo, puede convertir matrices basadas en cero de cualquier rango creado con CreateInstance(Type, Int32[], Int32[]) en la matriz del lenguaje.However, you can cast zero based arrays of any rank created with CreateInstance(Type, Int32[], Int32[]) to the language's array. Por ejemplo, puede convertir una matriz de enteros de base cero de 2 dimensiones creada con este método al tipo de C# int[,] .For example, you can cast a 2-dimensional zero based integer array created with this method to C#'s int[,] type.

A diferencia de la mayoría de las clases, Array proporciona el CreateInstance método, en lugar de los constructores públicos, para permitir el acceso enlazado en tiempo de ejecución.Unlike most classes, Array provides the CreateInstance method, instead of public constructors, to allow for late bound access.
Los elementos de tipo de referencia se inicializan en null .Reference-type elements are initialized to null. Los elementos de tipo de valor se inicializan en cero.Value-type elements are initialized to zero.
Este método es una operación O ( n ), donde n es el producto de length1 , length2 y length3 .This method is an O(n) operation, where n is the product of length1, length2, and length3.
