在ApplicationParts.Remove（）之后删除文件

Question

将.dll文件添加到程序集（ApplicationParts.Add），并将其删除（ApplicationParts.RemoveAt）后，是否可以删除它？

var assembly = AssemblyLoadContext.Default.LoadFromAssemblyPath(pathToWrite + fileModel.Name + ".dll");
if (assembly != null)
{
    _partManager.ApplicationParts.Add(new AssemblyPart(assembly));
    CustomActionDescriptorChangeProvider.Instance.HasChanged = true;
    CustomActionDescriptorChangeProvider.Instance.TokenSource.Cancel();
}
_partManager.ApplicationParts.RemoveAt(3);
File.Delete(pathToWrite + fileModel.Name + ".dll");// error
