UploadStringCompletedEventArgs.Result 屬性

定義

命名空間:

System.Net

組件:

System.Net.WebClient.dll

來源:

WebClient.cs

取得伺服器對字串上傳作業 (呼叫 UploadStringAsync 方法所啟動) 的回應。

public:
 property System::String ^ Result { System::String ^ get(); };

public string Result { get; }

member this.Result : string

Public ReadOnly Property Result As String

屬性值

String

Byte 陣列，包含伺服器回應。

範例

下列程式代碼範例會顯示這個屬性的值。

void UploadStringCallback2( Object^ /*sender*/, UploadStringCompletedEventArgs^ e )
{
   String^ reply = dynamic_cast<String^>(e->Result);
   Console::WriteLine( reply );
}

private static void UploadStringCallback2(Object sender, UploadStringCompletedEventArgs e)
{
    string reply = (string)e.Result;
    Console.WriteLine(reply);
}

Private Shared Sub UploadStringCallback2(ByVal sender As Object, ByVal e As UploadStringCompletedEventArgs)
    Dim reply As String = CStr(e.Result)
    Console.WriteLine(reply)
End Sub

備註

您應該檢查 Error 和 Cancelled 屬性，以判斷上傳是否已完成。 Error如果屬性值為 Exception 物件，或Cancelled屬性值為 true，則異步操作未正確完成，且Result屬性值無效。
