JSON 序列化 Dynamics CRM

Question

我试图在自定义 activity 中序列化 JSON 中的约会。

这是class 的约会：

//<summary>
// Commitment representing a time interval with start/end times and duration.
// </summary>
//
[System.Runtime.Serialization.DataContractAttribute()]
[Microsoft.Xrm.Sdk.Client.EntityLogicalNameAttribute("appointment")]
[System.CodeDom.Compiler.GeneratedCodeAttribute("CrmSvcUtil", "7.1.0001.3108")]
public partial class Appointment : Microsoft.Xrm.Sdk.Entity, System.ComponentModel.INotifyPropertyChanging, System.ComponentModel.INotifyPropertyChanged
{

// <summary>
// Default Constructor.
// </summary>
public Appointment() : 
        base(EntityLogicalName)
{
}

public const string EntityLogicalName = "appointment";

public const int EntityTypeCode = 4201;

public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;

public event System.ComponentModel.PropertyChangingEventHandler PropertyChanging;

private void OnPropertyChanged(string propertyName)
{
    if ((this.PropertyChanged != null))
    {
        this.PropertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
    }
}
....

这是序列化的代码：

Entity entity = (Entity) context.InputParameters["Target"];

        ColumnSet csAll = new ColumnSet(true);
        Appointment appointment = (Appointment) service.Retrieve(entity.LogicalName, entity.Id, csAll);

        System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(typeof(Appointment));
        MemoryStream ms = new MemoryStream();
        serializer.WriteObject(ms, appointment);
        string jsonNotification = Encoding.Default.GetString(ms.ToArray());

并且当执行 activity 时，出现以下错误：

Unexpected exception from plug-in (Execute): SmartwatchMeeting_PushGCM.SmartwatchMeeting: System.Security.SecurityException: The data contract type 'System.Collections.Generic.KeyValuePair`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5csadsad089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5csadsad089]]' cannot be serialized in partial trust because the member 'key' is not public

我不明白我必须添加什么才能使其正常工作？

感谢您的帮助

Answer 1

您不能序列化类型的非 public 成员，因为沙箱强制执行部分信任，并且序列化程序利用反射。

您可以：

切换到 Isolation mode: None（仅限内部部署）
为你的数据写一个模型class，只有public个成员，然后包装记录。这会使您的代码更大，但适用于 Isolation mode: Sandbox
