Este método é uma operação O(1).This method is an O(1) operation.

Observação

Caso SetValue seja usado para atribuir null a um elemento de uma matriz de tipos de valor, todos os campos do elemento são inicializados em zero.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. O valor do elemento não é uma referência nula, e não pode ser encontrada procurando uma referência nula.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Observação

Caso SetValue seja usado para atribuir null a um elemento de uma matriz de tipos de valor, todos os campos do elemento são inicializados em zero.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. O valor do elemento não é uma referência nula, e não pode ser encontrada procurando uma referência nula.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Este método é uma operação O(1).This method is an O(1) operation.

Observação

Caso SetValue seja usado para atribuir null a um elemento de uma matriz de tipos de valor, todos os campos do elemento são inicializados em zero.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. O valor do elemento não é uma referência nula, e não pode ser encontrada procurando uma referência nula.The value of the element is not a null reference, and cannot be found by searching for a null reference.
