Question

我在使用Monodroid PCL库时遇到问题。所有电话都在工作，除了这一个：

client.PostFileWithRequest<DtoResponse>("createimage", ms, fileName, new Dto{ Id = id});

错误如下：

Object reference not set to an instance of an object at ServiceStack.Pcl.StringEqualityComparer.GetHashCode (System.String obj) [0x00000] in <filename unknown>:0

在此之前我们没有遇到此问题。我们使用的是3.9.71 monodroid编译的dll。它们不是PCL。这只是用v4 PCL版本说的。有没有人以前遇到过这个问题，你是怎么解决的？
