示例1: CanSupplyValue

/// Returns true if the parameter is able to provide a value to a particular site.
/// </summary>
/// <param name="pi">Constructor, method, or property-mutator parameter.</param>
/// <param name="context">The component context in which the value is being provided.</param>
/// <param name="valueProvider">If the result is true, the valueProvider parameter will
/// be set to a function that will lazily retrieve the parameter value. If the result is false,
/// will be set to null.</param>
/// <returns>True if a value can be supplied; otherwise, false.</returns>

// in the container update situation.
