Strings are immutable, but StringBuilders aren't, maybe you want one of those?

There are a couple of ways you might want to look at.
The first is to return the new value as the result of the method:

C#

public static string poop(string hi)
   {
   return hi.TrimStart();
   }

You would then use it like this:

C#

string trimmed = poop("   Hello World!   ");
Console.WriteLine(trimmed);

The second is to pass a reference to the parameter:

C#

public static void poop(ref string hi)
   {
   hi = hi.TrimStart();
   }

And you then use it like this:

C#

string untrimmed = "   Hello World!   ";
poop(ref untrimmed);
Console.WriteLine(untrimmed);

In both cases, it will print "Hello World! " on the console.
