Silverlight文件找不到System.Runtime.Serialization从Newtonsoft的反序列化 [英] Silverlight File Not Found System.Runtime.Serialization on Deserialization from Newtonsoft

问题描述

尝试反序列化JSON时，我遇到异常。我的理解是，该文件是由用户本地文件系统上的Silverlight Runtime提供的，不需要包含在XAP文件中。

  T result = default（T）; 
 
 result = JsonConvert.DeserializeObject< T>（data）;任何想法，为什么我得到这个错误？

编辑：
 
 
 
以下是使用系统的T 
 的示例。 
使用System.Runtime.Serialization; 
 
命名空间MyNs 
 {
 [DataContract] 
 public class ClientQuery 
 {
 [DataMember] 
 public int ClientId {get ;组; } 
 
 [DataMember] 
 public string ClientName {get;组; 
} 
} 
  
 
 
解决方案
问题是我们为Silverlight 4构建了一个Newtonsoft.Json.dll。它是4.0.5.14411版本，它不是针对Silverlight 5构建的。当Visual Studio构建解决方案时，它会将项目正确映射到正确的System.Runtime。序列化dll排队使用MSBUILD的TFS中的版本不会。
 
 
 
我升级到最新版本，并解决了这个问题。
 
I am getting an exception when trying to deserialize JSON. It is my understanding that this file is provided by the Silverlight Runtime on the users local file system and should not need to be included in the the XAP files.
T result = default(T);

result = JsonConvert.DeserializeObject<T>(data);
Any ideas as to why I am getting this error?

EDIT:

Here's a sample of T
using System;
using System.Runtime.Serialization;

namespace MyNs
{
    [DataContract]
    public class ClientQuery
    {
        [DataMember]
        public int ClientId { get; set; }

        [DataMember]
        public string ClientName { get; set; }
    }
}

解决方案
The issue is we had a Newtonsoft.Json.dll built for Silverlight 4.  It was version 4.0.5.14411 which wasn't built for Silverlight 5.  When Visual Studio builds the solution, it correctly maps the project to the correct System.Runtime.Serialization dll.  Queueing a build in TFS that utilizes MSBUILD does not.

I upgraded to the newest version and that fixed the issue.
