在.NET中使用System.String.Copy有什么用？

using System;

class Program
{
    static void Main()
    {
        string originalString = "Hello, World!";
        string copiedString = originalString.Copy();

        // Modify the copied string
        copiedString = "Hello, Universe!";

        // The original string remains unchanged
        Console.WriteLine(originalString); // Output: "Hello, World!"
        Console.WriteLine(copiedString); // Output: "Hello, Universe!"
    }
}

string originalString = "Hello, World!";
string copiedString = originalString;
