在Web服务中接收JSON数组作为参数

我正在使用在Visual Basic .NET 3.5中编程的Web服务接收从其他应用程序发送的JSON数组。在Web服务中接收JSON数组作为参数

我送一个JSON字符串像这样的：

[{"idRecoleccion":1,"PIN":"553648138"},{"idRecoleccion":2,"PIN":"553648138"}]

而且我接受在Visual Basic .NET代码如下：

<WebMethod()> _ 
Public Function ConfirmaRecol(ByVal ArrayConfirma() As cConfirmaRecoleccion) As Boolean 
    For X = 0 To ArrayConfirma.Length -1 
       ' Usage example 
       ArrayConfirma(X).PIN 
       ArrayConfirma(X).idRecoleccion 
     End If 
    Next 
End Function

而且我定义class cConfirmaRecolecciones这样：

Public Class cConfirmaRecoleccion 
Dim p_idRecoleccion As Integer 
Dim p_PIN As String 

Public Property idRecoleccion() As Integer 
    Get 
     Return p_idRecoleccion 
    End Get 
    Set(ByVal value As Integer) 
     p_idRecoleccion = value 
    End Set 
End Property 

Public Property PIN() As String 
    Get 
     Return p_PIN 
    End Get 
    Set(ByVal value As String) 
     p_PIN = value 
    End Set 
End Property 
End Class

我只是想能够使用1整数和1字符串的数组是由JSON发送，这就是为什么我试图用他的方式。

几个重要事项：

我已经能够与具有更简单的参数，以便我必须使用Web服务的配置是正确的方法使用Web服务。

这是我由服务器得到的错误：

{"Message":"Type \u0027System.Collections.Generic.IDictionary`2[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]\u0027 is not supported for deserialization of an array.","StackTrace":" at System.Web.Script.Serialization.ObjectConverter.ConvertListToObject(IList list, Type type, JavaScriptSerializer serializer, Boolean throwOnError, IList& convertedList)\r\n at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.GetRawParamsFromPostRequest(HttpContext context, JavaScriptSerializer serializer)\r\n at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

你大师对我如何在Visual Basic .NET接收自定义对象的数组任何其他建议吗？

任何帮助将不胜感激！

Curro，请不要在标题中重复“VB.NET”等标签。只需将其留在标签中。 – 2010-07-06 00:33:34

明白了，谢谢！ – Arturo 2010-07-06 01:17:42

我找到了解决办法，这是正确的方式：

{"ArrayConfirma": [{"idRecoleccion":1,"PIN":"553648138"},{"idRecoleccion":2,"PIN":"553648138"}]}

我必须指定与论点，即Web服务方法接收名称的数组。
