ParametersOutProviderInitEventArgs.ParameterOutProperties 属性

请注意：此 API 现在已过时。

获取或设置参数提供的ParametersOutProviderInit事件发生时实现IParametersOutProvider接口的 Web 部件的数组的属性值。

命名空间：  Microsoft.SharePoint.WebPartPages.Communication
程序集：  Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）

语法

声明
<ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")> _
Public Property ParameterOutProperties As ParameterOutProperty()
    Get
    Set
用法
Dim instance As ParametersOutProviderInitEventArgs
Dim value As ParameterOutProperty()

value = instance.ParameterOutProperties

instance.ParameterOutProperties = value

[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")]
public ParameterOutProperty[] ParameterOutProperties { get; set; }

属性值

类型：[]
指定参数值的类型ParameterOutProperty数组。

备注

ParameterOutProperties属性提供了ParameterOutProperty的对象的数组，其中每个对应于一个参数。数量和参数表示该数组中的顺序必须匹配ParametersOutReady事件的ParametersInReadyEventArgs参数中指定的那些。

示例

下面的代码示例演示使用ParametersOutProperties属性设置的值为ParametersOutProviderInitEventArgs类的实例的数组重写的PartCommunicationInit方法。此代码示例是示例的一个更大提供的IParametersOutProvider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 that all of the Web Part's controls are created.
    EnsureChildControls();

    // Check if connected.
    if(_connected)
    {
        // If there is a listener, send init event.
        if (ParametersOutProviderInit != null)
        {
            // Need to create the ParametersOutProviderInitEventArgs object for the ParametersOutProviderInit event.
            ParametersOutProviderInitEventArgs parametersOutProviderInitInitEventArgs = new ParametersOutProviderInitEventArgs();
            
            // Set the ParameterOutProperties.
            parametersOutProviderInitInitEventArgs.ParameterOutProperties = new ParameterOutProperty[4];

            // There are 4 parameters types that will be passed: Font Family, Color, Weight, and Size.
