如何CompilationRelaxations.NoStringInterning实际工作？ [英] How does CompilationRelaxations.NoStringInterning actually work?

问题描述

我有证明NoStringInterning问题

I am having problems demonstrating NoStringInterning

[assembly: System.Runtime.CompilerServices.CompilationRelaxations(System.Runtime.CompilerServices.CompilationRelaxations.NoStringInterning)]

    class Program
    {
        static void Main(string[] args)
        {
            String s1 = "Friday";
            String s2 = "Friday";
            String s3 = "Friday";
            String s4 = "Friday";
            String s5 = "Friday";
            String s6 = "Friday";
            String s7 = "Friday";
            String s8 = "Friday";
            String s9 = "Friday";
            // etc...
            Console.WriteLine(Object.ReferenceEquals(s1, s2));
            Console.WriteLine(Object.ReferenceEquals(s1, s3));
            Console.WriteLine(Object.ReferenceEquals(s1, s4));
            Console.WriteLine(Object.ReferenceEquals(s1, s5));
            Console.WriteLine(Object.ReferenceEquals(s1, s6));
            Console.WriteLine(Object.ReferenceEquals(s1, s7));
            Console.WriteLine(Object.ReferenceEquals(s1, s8));
            Console.WriteLine(Object.ReferenceEquals(s1, s9));
            // etc...

我试过用.NET CLR 2，3 4 ..作为输出我得到的是一堆真。我期待了一堆假的！

I've tried with .NET CLR 2, 3, 4.. as output all I get is a bunch of True. I am expecting a bunch of False!

推荐答案

的文档指出属性：

标记的组装为不需要字符串字面实习。

Marks an assembly as not requiring string-literal interning.

在换句话说，它不能阻止从做串实习，只是提供，它不要求一个提示的编译器。该文档是在这方面有点稀疏，但是这也似乎是在的这个MSDN论坛帖子。

In other words, it does not prevent the compiler from doing string interning, just providing a hint that it is not required. The documentation is a little bit sparse in this area, but this also seems to be the conclusion in this MSDN forum post.
