asp.net - 在服务“EditInitiatives”的合同列表中找不到合同名称“MyCompany.CostReduction.EditInitiatives”

Question

对于基于 ajax 的 WCF 服务，我遇到了上述错误。代码如下所示。

代码

    <ServiceContract()>
    Public Interface IEditInitiatives
        <OperationContract()> _
       <WebInvoke(BodyStyle:=WebMessageBodyStyle.WrappedRequest, ResponseFormat:=WebMessageFormat.Json, UriTemplate:="GetGridData")> _
        Function GetGridData(session As String) As List(Of InitiativeData)    

        <OperationContract()> _
        <WebInvoke(Method:="POST", BodyStyle:=WebMessageBodyStyle.WrappedRequest, ResponseFormat:=WebMessageFormat.Json)> _
        Function SaveGridData(input As String) As String

    End Interface    
    <AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>
    Public Class EditInitiatives
        Implements IEditInitiatives


        Function GetGridData(session As String) As List(Of InitiativeData) Implements IEditInitiatives.GetGridData
           'Business logice
        End Function

        Function SaveGridData(ByVal input As String) As String Implements IEditInitiatives.SaveGridData

            Return "ok"
        End Function

End Class

试一试：

[Serializable]
[DataContract]

确保将这些属性放在 InitiativeData

using System.Collections.ObjectModel;
using System.Runtime.Serialization;
