Bing-Map-API我做錯了什麼？

Question

我正在嘗試爲我的學校使用Bing Map API並使用GeocodeAdress。我建立這個應用程序：http://msdn.microsoft.com/en-us/library/dd221354.aspx和問題是我每次都得到這個錯誤。

它在第62行：此方法：GeocodeServiceClient geocodeService = new GeocodeServiceClient（）; ！

InvalidOperationException異常是未處理 「System.InvalidOperationException」類型的未處理的異常出現在System.ServiceModel.dll

其他信息：合同「GeocodeService.IGeocodeService」端點配置部分無法加載，因爲更多比找到該合同的一個端點配置。請按名稱指出首選的端點配置部分。

下面是代碼：

    private void Search_Click(object sender, RoutedEventArgs e) 
    {

} 
} 

我找到了解決辦法行62應該是：

var geocodeService = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");

打開你的web.config文件或app.config文件。在那裏，您將看到該服務的基本和自定義綁定配置。刪除自定義綁定部分。清理和建立你的項目，它應該工作。

作爲一個側面說明。 Bing Maps SOAP服務非常陳舊，功能有限。他們在大約8年前被釋放。大約4年前發佈了一種更新的基於REST的服務。 REST速度更快，響應包更小，功能更多。您可以在此處瞭解有關Bing Maps REST服務的更多信息：http://msdn.microsoft.com/en-us/library/ff701713.aspx
