FullTrust用于调用流程成员 [英] FullTrust for calling Process members

问题描述

你好，


我必须从一个进程调用Handle并且需要FullTrust

否则它会发生异常。

目前我只使用这个代码并发生异常。

[PermissionSet（SecurityAction.LinkDemand，Name =" FullTrust"）]

PermissionState.Unrestricted如何实施？

jeff

解决方案

Jeffrey，


你能更具体一点吗？在确定授予应用程序的权限时，有很多事情需要确定。你的

应用程序是一个ASP.NET应用程序，还是一个Windows窗体应用程序？


另外，你提到的代码是一个属性，没有什么真正的

本身执行。无论该属性应用于什么，都要求来电者完全信任（这不是你想要的）。


你想做什么？ ？

PermissionState.Unrestricted如何实现？

jeff

这就是我所猜测的，当前进程无权使用该进程

句柄，这有与CAS无关，它是Windows安全的东西。

普通用户（甚至是管理员）没有无限制的权限，所以这是非常正常的应用程序无法调用OpenProcess（...）。


你想要实现什么？

它是一个Windows应用程序。
句柄是来自System.Diagnostics.Process类的句柄。
例外是一个
System.ComponentModel .Win32Exception：Zugriff verweigert
在System.Diagnostics.ProcessManager.OpenProcess（Int3 2 processId，
Int32 access，Boolean throwIfExited）
在System.Diagnostics.Process.GetProcessHandle（Int32 access，Boolean <在System.Diagnostics.Process.Terocess.and处理系统中，System.Diagnostics.Process.OpenProcessHandle（）上的System.Diagnostics.Process.GetProcessHandle（Int32访问）

br />

什么例外？用call the Handle是什么意思，如果你的意思是

使用Process句柄，那么你的异常与CAS无关。一个

pocess句柄是一个内核对象，受ACL保护。

目前我只使用这个代码并发生异常。
[PermissionSet（SecurityAction.LinkDemand，Name =" FullTrust"）]

PermissionState.Unrestricted如何实现？

jeff

hello,

I have to call the Handle from a process and FullTrust is needed
otherwise it happens an exception.
currently i am using only this code and the exception occurs.
[PermissionSet(SecurityAction.LinkDemand, Name="FullTrust")]
how is PermissionState.Unrestricted to implement?
jeff

解决方案

Jeffrey,

Can you be a little more specific? There are a lot of things that go
into determining the permissions that an application is granted. Is your
app an ASP.NET app, or a windows forms app?

Also, the code you mentioned is an attribute, there is nothing really
executed per-se. Whatever that attribute is applied to is demanding full
trust from the caller (which isn''t what you want).

What are you trying to do?

That''s what I guessed, the current process has no rights to use the process
handle, this has nothing to do with CAS, it''s a windows security thing.
Regular users (even administrators) have no unlimited privileges, so it''s
quite normal the your application cannot call OpenProcess(...).

What are you trying to achieve?

it is a windows app.
the handle is a Handle from the System.Diagnostics.Process class.
the exception is a
System.ComponentModel.Win32Exception: Zugriff verweigert
at System.Diagnostics.ProcessManager.OpenProcess(Int3 2 processId,
Int32 access, Boolean throwIfExited)
at System.Diagnostics.Process.GetProcessHandle(Int32 access, Boolean
throwIfExited)
at System.Diagnostics.Process.GetProcessHandle(Int32 access)
at System.Diagnostics.Process.OpenProcessHandle()
at System.Diagnostics.Process.get_Handle()

What exception? What do you mean exactly with "call the Handle", if you mean
use the Process handle, then your exception has nothing to do with CAS. A
pocess handle is a kernel object and is protected by an ACL.
