BeginGetInstance(Guid, InstanceStore, AsyncCallback, Object)

使用带指定的实例标识符、实例存储区、回调和状态的 IAsyncResult 异步设计模式异步检索实例所有者。

public:
 static IAsyncResult ^ BeginGetInstance(Guid instanceId, System::Runtime::DurableInstancing::InstanceStore ^ instanceStore, AsyncCallback ^ callback, System::Object ^ state);

public static IAsyncResult BeginGetInstance (Guid instanceId, System.Runtime.DurableInstancing.InstanceStore instanceStore, AsyncCallback callback, object state);

static member BeginGetInstance : Guid * System.Runtime.DurableInstancing.InstanceStore * AsyncCallback * obj -> IAsyncResult

Public Shared Function BeginGetInstance (instanceId As Guid, instanceStore As InstanceStore, callback As AsyncCallback, state As Object) As IAsyncResult

参数

instanceId: Guid

实例标识符。

instanceStore: InstanceStore

对工作流应用程序的当前实例保留状态的访问。

callback: AsyncCallback

要在开始加载操作完成后调用的方法。

state: Object

一个特定于应用程序的可选对象，其中包含有关异步操作的信息。

IAsyncResult

对异步操作的引用。
