示例

下面的代码示例演示重写的PartCommunicationInit方法创建ParametersInConsumerInitEventArgs类的实例，并通过创建ParameterInProperty类的实例定义参数值。此代码示例是示例的一个更大提供的IParametersInConsumer接口的一部分。

// Step #7: Override the PartCommunicationInit method.
// The PartCommunicationInit method is called by the Web Part infrastructure during the ASP.NET PreRender 
// event to allow the part to pass initialization information to the other connected parts.
// It is important to always pass initialization information. Some parts
// may not behave properly if this initialization information is not received.
public override void PartCommunicationInit()
{
    // Ensure all controls have been created.
    EnsureChildControls();

    // Check if connected.
    if(_connected)
    {
        // If there is a listener, fire the ParametersInConsumerInit event.
        if (ParametersInConsumerInit != null)
        {
            // Need to create the ParametersInConsumerInitEventArgs object for the ParametersInConsumerInit event.
            ParametersInConsumerInitEventArgs parametersInConsumerInitEventArgs = new ParametersInConsumerInitEventArgs();
            
            // Set the ParameterInProperties.
