背景: 我正在使用ASP.NET 2.0創建Web服務。此Web服務爲現有Web表單提供了另一個接口,其中包含從數據庫動態填充的選擇框。將WSDL枚舉映射爲ASP.NET webservice中的字符串
我的第一份Web服務草案接受了每一個這樣的字符串,然後確保它是有效的,如果不是這樣的話就拋出一個錯誤。然而,Web服務的使用者詢問,因爲可能的值不可能經常改變,所以我們在WSDL中提供了枚舉值。
我不願意用我的Web服務代碼創建一個枚舉,所以我改變了生成的WSDL文件,並指示我的Web服務使用它而不是檢查我的類來生成它。

web服務:
namespace Example.Service
{
[WebService(Namespace = "http://example.org/")]
[WebServiceBinding(
ConformsTo = WsiProfiles.BasicProfile1_1,
Location="ExternalAccess.wsdl",
Name="ExternalAccessSoap",
Namespace = "http://example.org/")]
[ToolboxItem(false)]
public class ExternalAccess : System.Web.Services.WebService
{
public class MyClass
{
public string MyString;
}
[WebMethod]
[SoapDocumentMethod(
Action = "http://example.org/MyMethod",
RequestNamespace = "http://example.org/",
Binding="ExternalAccessSoap")]
public void MyMethod(MyClass myClass)
{
}
}
}
問題: 作爲WSDL指定MyString中的列舉以及代碼中指定的字符串類型,ASP。 NET不管理正確地映射字段。
是否有一個屬性可以用來指示反序列化器使用枚舉的值填充字符串字段?
問候,
