Question

I’m facing this abnormal situation. The following code doesn’t work properly:

        string temp = "heythere";
        Console.WriteLine(temp);
        temp.Insert(3, "hello");
        Console.WriteLine(temp);

Isn’t it supposed to output like “heyhellothere” ? But it does “heyrehere” (no change).

Strings are immutable, they don’t change in-place. Try:

string temp = "heythere";
Console.WriteLine(temp);
temp = temp.Insert(3, "hello");
Console.WriteLine(temp);
