c# - 有没有办法在C#中修改进程DACL

我有旧的C++代码，它会更改进程DACL，并且正在尝试使用.NET 3.5中的托管代码类。我在网上找到了一些代码，其中有人创建了一个SetAclOnServices类，该类扩展了服务的NativeObjectSecurity类。我以为可以实现这一点，只需将ResourceType.Service更改为ResourceType.KernelObject，但是当我调用GetAccessControl时，它将失败并显示File Not Found错误。

最佳答案

圣诞节快乐。

public class ProcessSecurity : NativeObjectSecurity
{
    public ProcessSecurity(SafeHandle processHandle)
        : base(false, ResourceType.KernelObject, processHandle, AccessControlSections.Access)
    {

    }

    public void AddAccessRule(ProcessAccessRule rule)
    {
        base.AddAccessRule(rule);
    }

    // this is not a full impl- it only supports writing DACL changes
    public void SaveChanges(SafeHandle processHandle)
    {
        Persist(processHandle, AccessControlSections.Access);
    }

    public override Type AccessRightType
    {
        get { return typeof(ProcessAccessRights); }
    }

    public override AccessRule AccessRuleFactory(System.Security.Principal.IdentityReference identityReference, int accessMask, bool isInherited, InheritanceFlags inheritanceFlags, PropagationFlags propagationFlags, AccessControlType type)
    {
        return new ProcessAccessRule(identityReference, (ProcessAccessRights)accessMask, isInherited, inheritanceFlags, propagationFlags, type);
    }

    public override Type AccessRuleType
    {
        get { return typeof(ProcessAccessRule); }
    }

    public override AuditRule AuditRuleFactory(System.Security.Principal.IdentityReference identityReference, int accessMask, bool isInherited, InheritanceFlags inheritanceFlags, PropagationFlags propagationFlags, AuditFlags flags)
    {
        throw new NotImplementedException();
    }

    public override Type AuditRuleType
    {
        get { throw new NotImplementedException(); }
    }
}

public class ProcessAccessRule : AccessRule
{
    public ProcessAccessRule(IdentityReference identityReference, ProcessAccessRights accessMask, bool isInherited, InheritanceFlags inheritanceFlags, PropagationFlags propagationFlags, AccessControlType type)
        : base(identityReference, (int)accessMask, isInherited, inheritanceFlags, propagationFlags, type)
    {
    }

    public ProcessAccessRights ProcessAccessRights { get { return (ProcessAccessRights)AccessMask; } }
}
