所以我想出了如何将我的自定义对象传递给 ASP.Net json webservices。很有魅力。

我遇到的问题是传入自定义对象的直接数组，或者传入作为自定义对象参数的数组。

所以例如...

Public Class WebService1
    Inherits System.Web.Services.WebService

    <WebMethod()> _
    <ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _
    Public Function AddPersonList(ByVal PersonList As PersonList) As String
        Debug.Assert(False)
    End Function

    Public Class Person
        Public Sub New()
        End Sub

        Public Property FirstName As String
        Public Property LastName As String
    End Class

    Public Class PersonList
        Inherits List(Of Person)

    End Class
End Class

<script>
        $(function () {
            $.ajax({
                type: "POST",
                url: "WebService1.asmx/AddPersonList",
                data: " { PersonList: [ { FirstName: 'Max', LastName: 'Gershkovich' }, { FirstName: 'Test1', LastName: 'Test2' } ] }",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (e) { debugger; },
                error: function (e) { debugger; }
            });
        });
    </script>

Public Function AddPersonList(ByVal PersonList As String) As PersonList

Dim PersonList As PersonList = jsonSerializer.Deserialize(Of PersonList)(PList)

Dim jsonSerializer As New JavaScriptSerializer(New MyCustomTypeResolver)

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization>
          <converters>
            <add name="MyCustomConverter" type="WebApplication1.MyCustomConverter" />
          </converters>
        </jsonSerialization>
      </webServices>      
    </scripting>
  </system.web.extensions>

Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS EmailAddressList}

Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS List(Of EmailAddress)} 

最佳答案

首先是数据

{ PersonList: [ { FirstName: 'Max', LastName: 'Gershkovich' }, { FirstName: 'Test1', LastName: 'Test2' } ] }

{"PersonList":[{"FirstName":"Max","LastName":"Gershkovich"},{"FirstName":"Test1","LastName":"Test2"}]}

$.ajax({
    data: {PersonList:JSON.stringify(t)} 
    // other parameters
});

$.ajax({
    data: JSON.stringify({ PersonList: t })
    // other parameters
});

var t = [ { FirstName: 'Max', LastName: 'Gershkovich' },
          { FirstName: 'Test1', LastName: 'Test2' } ];

Public Class EmailAddress
    Public Property Type As String
    Public Property Address As String
End Class

Public Class Customer
    'Public CustomerID As Guid
    Public Property FirstName As String
    Public Property LastName As String
    Public Property EmailAddresses As List(Of EmailAddress)
End Class

<WebMethod()> _
Public Function AddPersonList(ByVal PersonList As List(Of Customer)) As String

<WebMethod()> _
Public Function AddPersonList1(ByVal input As InputData) As String

Public Class InputData
    Public Property PersonList As List(Of Customer)
End Class

var myData = [
        { FirstName: 'Max', LastName: 'Gershkovich',
            EmailAddresses: [
                { Type: 'SMTP', Address: 'Max.Gershkovich@googlemail.com' },
                { Type: 'SMTP', Address: 'Max.Gershkovich@mail.ru' },
            ]
        },
        { FirstName: 'Test1', LastName: 'Test2' }
    ];

$.ajax({
    type: "POST",
    url: "WebService1.asmx/AddPersonList",
    data: JSON.stringify({ PersonList: myData }),
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data) {
        alert(data.d);
    },
    error: function (xhr, textStatus, errorThrown) {
        alert("Error Occured!" + " | " + xhr.responseText + " | " +
              textStatus + " | " + errorThrown);
    }
});

$.ajax({
    type: "POST",
    url: "WebService1.asmx/AddPersonList1",
    data: JSON.stringify({ input: {PersonList: myData} }),
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data) {
        alert(data.d);
    },
    error: function (xhr, textStatus, errorThrown) {
        alert("Error Occured!" + " | " + xhr.responseText + " | " +
              textStatus + " | " + errorThrown);
    }
});
