Valor de propiedad

Tipo: []
Una matriz de valores de parámetro.

Comentarios

La propiedad ParameterValues es una matriz unidimensional de cadenas, donde cada cadena es el valor de un parámetro. El número y el orden de los parámetros contenidos en esta matriz deben coincidir con los especificados en el argumento de ParametersOutProviderInitEventArgs del evento ParametersOutProviderInit .

Ejemplos

En el ejemplo de código siguiente se muestra un método invalidado PartCommuncationMain que usa la propiedad ParameterValues para establecer los valores de parámetros de una instancia de la clase ParametersOutReadyEventArgs . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz IParametersOutProvider .
