Prevents a stack walk originating lower in the call stack from proceeding up the call stack beyond the code that calls this method 就能防止调用堆栈中从较低位置开始的堆栈遍历沿着调用堆栈向上超出调用此方法的代码。
If the demand succeeds , only one stack walk is performed and the method reads the creation time from every file in the passed directory 如果要求成功,则仅执行一次堆栈步,该方法读取传递的目录中每个文件的创建时间。
During a stack walk , if a stack frame asserting the required permission is encountered , a security check for that permission will succeed 在堆栈步期间,如果遇到断言所需要的权限的椎栈帧,对该权限的安全检查将会成功。
However , this optimization does not cause an elevation of privilege because a stack walk is still performed when calling assemblies are present 但是,此优化不会引起特权提升,因为当调用程序集存在时,堆栈审核仍会执行。
Method reads information from the files but requires a demand and stack walk for every file it reads . the method creates a new instance of the 方法读取文件的信息,但对它读取的每个文件,都需要一个要求和进行一次堆栈步。
Because the demanded permission is a subset of the asserted permission , the stack walk stops and the security check automatically succeeds 因为请求的权限( p1a )是断言的权限( p1 )的子集,所以堆栈步会停止,安全检查自动成功。
This attribute replaces the full stack walk at run time with a check that only verifies the permissions of the immediate caller at link time 此属性将运行时的完整堆栈步替换为一个检查,该检查仅在链接时验证直接调用方的权限。
Then , assert permission x , which causes subsequent stack walks to stop at method m and succeed , thereby reducing the number of permission comparisons by 99 然后,断言权限x ,这使随后的堆栈步在方法m处停止并成功,从而减少了99
