如何CompilationRelaxations.NoStringInterning实际工作？(Ho

我有证明NoStringInterning问题

[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...

我试着用.NET CLR 2，3，4 ..作为输出我得到的是一堆真。我期待一堆假的！

Answer 1:

The documentation states that the attribute:

Marks an assembly as not requiring string-literal interning.

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.
