Definição

Obtém ou define o período de tempo de espera para que um objeto se torne disponível no pool antes de gerar uma exceção. Esse valor é em milissegundos.

public:
 property int CreationTimeout { int get(); void set(int value); };
public int CreationTimeout { get; set; }
member this.CreationTimeout : int with get, set
Public Property CreationTimeout As Integer

Valor da propriedade

O valor de tempo limite em milissegundos.
