Question

我想分享我在不同的exe之间创建的DLL。每个文件都在同一个地图中。但是，我如何才能将我的数据从一个exe更改为一个dll，同时还能看到另一个dll中的更改？

在互联网上看起来我需要使用WCF服务。但我所做的只是本地的，所以我想知道他们别无他法吗？

如果没有其他办法，我的WCF服务也出现问题，我收到以下错误：

Newtonsoft.Json.Linq.JToken类型是递归数据收集合约。这不受支持。要通过更改集合Newtonsoft.Json.Linq.JToken的定义来解决此问题，以便它不包含对自己的引用。

好的是我的代码：

Answer 1

正如您所怀疑的那样 - DLL只共享代码 - 而不是数据。每个都将是一个单独的过程。

有两种方法可以在两个进程之间共享 - 您可能感兴趣的一个选项是Shared Memory / Memory mapped files。

C＃在不同的exe之间共享不同的dll
