ClientBase<TChannel>.BeginOperationDelegate 委托

定义

命名空间:

System.ServiceModel

程序集:

System.ServiceModel.Primitives.dll

包:

System.ServiceModel.Primitives v8.0.0

一个委托，由 InvokeAsync(ClientBase<TChannel>.BeginOperationDelegate, Object[], ClientBase<TChannel>.EndOperationDelegate, SendOrPostCallback, Object) 用于调用客户端的异步操作。

protected:  where TChannel : classdelegate IAsyncResult ^ ClientBase<TChannel>::BeginOperationDelegate(cli::array <System::Object ^> ^ inValues, AsyncCallback ^ asyncCallback, System::Object ^ state);

protected delegate IAsyncResult ClientBase<TChannel>.BeginOperationDelegate(object[] inValues, AsyncCallback asyncCallback, object state) where TChannel : class;

Protected Delegate Function ClientBase(Of TChannel).BeginOperationDelegate(inValues As Object(), asyncCallback As AsyncCallback, state As Object) As IAsyncResult 

参数

inValues

Object[]

异步调用的输入值。

asyncCallback

AsyncCallback

引用在相应异步操作完成时调用的方法。

state

Object

一个 Object，可让客户端区分不同的异步调用。 客户端可在事件完成回调的自变量参数中进行使用。

返回值

IAsyncResult

异步调用的结果。
