c# - System.InvalidOperationException 指定された型は認識されませんでした

Question

私は得る：

The specified type was not recognized: name='ur-type', namespace='http://www.w3.org/2001/XMLSchema', at <response xmlns=''>.

Web サービスを呼び出そうとしたとき。奇妙なことは、SoapUI でテストしている間、リクエストが機能していることです。

私のスタック トレースは次のようになります。

    [InvalidOperationException: The specified type was not recognized: name='ur-type', namespace='http://www.w3.org/2001/XMLSchema', at <response xmlns=''>.]

   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3707

このエラーの原因は何ですか?

アップデート：

//Calling code

garage_portClient proxy = new garage_portClient();
cars = proxy.getCars(CarBrand.SelectedValue, FuelType.SelectedValue);
