ParametersOutProviderInitEventArgs 类
请注意：此 API 现在已过时。
提供的参数数组向IParametersOutProvider接口的ParametersOutProviderInit初始化事件的属性值。
继承层次结构
System.Object
System.EventArgs
Microsoft.SharePoint.WebPartPages.Communication.InitEventArgs
Microsoft.SharePoint.WebPartPages.Communication.ParametersOutProviderInitEventArgs
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 NotInheritable Class ParametersOutProviderInitEventArgs _
Inherits InitEventArgs
用法
Dim instance As ParametersOutProviderInitEventArgs
[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")]
public sealed class ParametersOutProviderInitEventArgs : InitEventArgs
示例
下面的代码示例演示创建ParametersOutProviderInit事件中定义的参数将传递ParametersOutProviderInitEventArgs类的实例重写的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
' phase 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.
