public:
 virtual System::Threading::Tasks::Task ^ DispatchEventAsync(System::UInt64 eventHandlerId, Microsoft::AspNetCore::Components::RenderTree::EventFieldInfo ^ fieldInfo, EventArgs ^ eventArgs);

public virtual System.Threading.Tasks.Task DispatchEventAsync (ulong eventHandlerId, Microsoft.AspNetCore.Components.RenderTree.EventFieldInfo? fieldInfo, EventArgs eventArgs);

abstract member DispatchEventAsync : uint64 * Microsoft.AspNetCore.Components.RenderTree.EventFieldInfo * EventArgs -> System.Threading.Tasks.Task
override this.DispatchEventAsync : uint64 * Microsoft.AspNetCore.Components.RenderTree.EventFieldInfo * EventArgs -> System.Threading.Tasks.Task

Public Overridable Function DispatchEventAsync (eventHandlerId As ULong, fieldInfo As EventFieldInfo, eventArgs As EventArgs) As Task

参数

eventHandlerId

UInt64

AttributeEventHandlerId原始事件属性中的值。

fieldInfo

EventFieldInfo

呈现器可用于更新现有呈现树的状态以匹配 UI 的信息。

eventArgs

EventArgs

要传递给事件处理程序的参数。

返回

Task

一个 Task ，它将在与事件相关的所有异步处理完成后完成。
