用于创建文件的安全权限 [英] security permissions for creating a file

问题描述

你好，


在一个简单的控制台应用程序中我尝试用以下代码创建一个文件：


FileStream file = new FileStream （" test.txt"，FileMode.OpenOrCreate，

FileAccess.Write）;

StreamWriter sw = new StreamWriter（file）;

sw.Write（" Hello"）;

sw.Close（）;

file.Close（）;


我将得到一个错误System.Security.SecurityException


是否只有一种方法可以避免这种情况以及如何做到这一点？


谢谢并且问候

马克

Hello,

in a simple console application I try to create a file with some code like:

FileStream file = new FileStream("test.txt", FileMode.OpenOrCreate,
FileAccess.Write);
StreamWriter sw = new StreamWriter(file);
sw.Write("Hello");
sw.Close();
file.Close();

I will get an error System.Security.SecurityException

Are there only one way to avoid this and how this can be done?

Thanks and regards
Mark

推荐答案

马克，


你得到这个例外因为您没有权利在其设置的目录中创建或打开

文件。您需要尝试在目录中创建

文件您有权使用，或者，如果该文件存在，请检查

文件的权利，以确保您可以打开它进行写作。

希望这会有所帮助。

Mark,

You get this exception because you don''t have rights to create or open
the file in the directory that it is set in. You need to try and create the
file in a directory that you have rights to, or, if the file exists, check
the rights on the file to make sure that you can open it for writing.

Hope this helps.

嗨尼古拉斯，

我尝试了一个控制台应用程序，作为管理员，我在任何

目录中都没有限制。

Mark，

您有权访问的目录，或者，如果该文件存在，请检查文件上的权限，以确保您可以打开它进行写作。

您确定安全例外是否适用于然后打开文件？

从哪里加载应用程序？你是从网络运行它吗？b $ b股票还是互联网？如果是这样，那么应用程序将被授予

a有限权限设置。

Are you sure that the security exception is for opening the file then?
Where is the application loaded from? Are you running it from a network
share, or the internet? If so, then the application is going to be granted
a limited permission set.
