C# 4.0 我的servicestack缓存服务在响应中包含额外的斜杠

我已经使用ServiceStack创建了一个缓存的webservice

public class ContentSearchService : ServiceBase<ContentSearch>
{
    public ICacheClient CacheClient { get; set; }

    protected override object Run(ContentSearch request)
    {


        var cacheKey = "unique_key_for_this_request2";
        return base.RequestContext.ToOptimizedResultUsingCache(this.CacheClient, cacheKey, () =>
        {
            //Delegate is executed if item doesn't exist in cache


            //Any response DTO returned here will be cached automatically
            return new ContentSearchResponse()
            {
                Contents = new List<ContentData>()
                {
                    new ContentData()
                    {
                         FileName = "testfile.jpg"
                    }
                }
            };
        });
    }
}

第二项答复：

{"Contents":[{"FileName":"testfile.jpg","Company":0,"Version":0}]}

{\"Contents\":[{\"FileName\":\"testfile.jpg\",\"Company\":0,\"Version\":0}]}

我使用Redis作为缓存

我已经查看了redis服务器，它们是用斜杠存储的。

结果表明，这与使用不同版本的ServiceStack程序集的客户端有关。我最新更新了服务器和客户机，一切正常

{\"Contents\":[{\"FileName\":\"testfile.jpg\",\"Company\":0,\"Version\":0}]}
