名前空間: System.Web.Services.Protocols
アセンブリ: System.Web.Services (system.web.services.dll 内)
構文

Visual Basic (宣言)

Public Function BeginInvoke ( _
    target As Object, _
    values As Object(), _
    callback As AsyncCallback, _
    asyncState As Object _
) As IAsyncResult

Visual Basic (使用法)

Dim instance As LogicalMethodInfo
Dim target As Object
Dim values As Object()
Dim callback As AsyncCallback
Dim asyncState As Object
Dim returnValue As IAsyncResult

returnValue = instance.BeginInvoke(target, values, callback, asyncState)

C#

public IAsyncResult BeginInvoke (
    Object target,
    Object[] values,
    AsyncCallback callback,
    Object asyncState
)

C++

public:
IAsyncResult^ BeginInvoke (
    Object^ target, 
    array<Object^>^ values, 
    AsyncCallback^ callback, 
    Object^ asyncState
)

J#

public IAsyncResult BeginInvoke (
    Object target, 
    Object[] values, 
    AsyncCallback callback, 
    Object asyncState
)

JScript

public function BeginInvoke (
    target : Object, 
    values : Object[], 
    callback : AsyncCallback, 
    asyncState : Object
) : IAsyncResult

パラメータ

target

メソッドの呼び出し元となる Object のインスタンス。

values

呼び出すメソッドの引数リスト。これは、メソッドのパラメータと同じ数、順序、型のオブジェクトの配列です。メソッドにパラメータが必要ない場合、values は null 参照 (Visual Basic では Nothing) です。

callback

非同期呼び出しが完了したときに呼び出されるデリゲート。callback が null 参照 (Visual Basic では Nothing) の場合、このデリゲートは呼び出されません。

asyncState

デリゲートに渡されるステータス情報。

戻り値
リモート メソッドの呼び出しからの戻り値を取得するために、EndInvoke に渡される IAsyncResult。

例外

例外の種類	条件
TargetException	target パラメータが null 参照 (Visual Basic では Nothing) です。
ArgumentException	values の数、型、およびパラメータの順序が、呼び出されたメソッドのシグネチャと一致しません。
MemberAccessException	呼び出し元に、このメソッドを呼び出すためのアクセス許可がありません。
