Commenti

I metodi GetLowerBound e GetUpperBound possono determinare se uno degli indici è fuori limite.The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

Questo metodo è un'operazione O (1).This method is an O(1) operation.

Il numero di elementi in indices deve essere uguale al numero di dimensioni nel Array.The number of elements in indices must equal the number of dimensions in the Array. Tutti gli elementi nella matrice indices devono specificare collettivamente la posizione dell'elemento desiderato nell'@no__t multidimensionale-1.All elements in the indices array must collectively specify the position of the desired element in the multidimensional Array.

I metodi GetLowerBound e GetUpperBound possono determinare se uno degli indici è fuori limite.The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

Questo metodo è un'operazione O (1).This method is an O(1) operation.

Parametri

indices
Int64[]

Matrice unidimensionale di integer a 64 bit che rappresentano gli indici che specificano la posizione dell'elemento Array da ottenere.A one-dimensional array of 64-bit integers that represent the indexes specifying the position of the Array element to get.

Restituisce

Valore in corrispondenza della posizione specificata nell'oggetto Array multidimensionale.The value at the specified position in the multidimensional Array.

Eccezioni

Il numero di dimensioni nell'oggetto Array corrente non è uguale al numero di elementi in indices.The number of dimensions in the current Array is not equal to the number of elements in indices.

Qualsiasi elemento in indices non è compreso nell'intervallo di indici validi per la dimensione corrispondente dell'oggetto Array corrente.Any element in indices is outside the range of valid indexes for the corresponding dimension of the current Array.
