尝试在vps上运行steambot时出错debian System.MissingMethodException:方法未找到：'System.Array.Empty‘

Question

我已经建立了解决方案使用单开发窗口，然后转移到我的文件到我的vps使用Filezilla。它在窗户上很好用。但是，当我尝试使用mono steambot.exe运行steambot时，我会得到以下错误：

Unhandled Exception: System.MissingMethodException: Method not found: 'System.Array.Empty'.
  at SteamBot.Program.BotManagerMode () [0x00000] in <filename unknown>:0

单一版本：

再一次，在窗户上工作很好。VPS是Debian7.11 x32

Answer 1

public static T[] System.Array.Empty<T>()是在.Net 4.6中添加的，因此您的旧版本的Mono将运行.Net 4.5，并且预期会出现错误。

要么将Mono版本更新为4.8+，要么删除Array.Empty的使用，并根据.Net 4.5框架进行编译。
