fast return value

I have a large number of hard coded strings I want to return from a dll.
I'm under the impression the fastest way would be a string array of the type
string[] myarray = {"1","2","3"...}. (I'm under the impression this would
be much faster then adding each string to the array one at a time.) When I
do this, the compiler throws an error saying it has a max line size of 2046.
Is there a way around this or is there another fast/faster way to return the
list of strings.
Thanks,
Rick

I don't think so, that's what the compiler ends up doing anyway.

Do you have to put them all on one line? Add some line breaks and see
if it works better.

I guess that is part of my question, does anyone know for sure whether the
compiled version of : string[] myarray = {"1","2","3"...} is equivalent to
myarray.SetValue("1",1);myarray.SetValue("2",2) etc.

I've seen tests that show their are differences between other similar
operations, like stringa = stringb and stringa.Equals(stringb) etc that show
they are not treated all the same by the compiler, so I don't assume they
are the same in this case.

How do you propose I add line breaks? If I add a cr/lf it reads it as a
syntax error.

Thanks for any other thoughts you might have.

You don't have to involve SetValue calls, there are IL opcodes to
store array elements. Compile this code

void Foo()
{
string[] arr1 = {"a", "b", "c"};
string[] arr2 = new string[3];
arr2[0] = "x";
arr2[1] = "y";
arr2[2] = "z";
}

and check the result in your favorite disassembler/decompiler, and
you'll see that the two code segments are equivalent.

string[] s = {
"Your first really long string",
"Your second really long string",
"First part of the third string" +
"Second part of the third string"};
