C# 卸载AppDomain后删除dll文件
我目前正在尝试制作一个游戏引擎,尝试一块一块地复制unity功能, 对于加载一些脚本,我没有问题,但是当我必须重新加载它们时,mono编译失败,告诉我DLL已经被访问,或者DLL文件无法删除 这是我的密码:C# 卸载AppDomain后删除dll文件,c#,dll,mono,.net-assembly,appdomain,C#,Dll,Mono,.net Assembly,Appdomain,我目前正在尝试制作一个游戏引擎,尝试一块一块地复制unity功能, 对于加载一些脚本,我没有问题,但是当我必须重新加载它们时,mono编译失败,告诉我DLL已经被访问,或者DLL文件无法删除 这是我的密码: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Reflection; using
