Basically what I'm trying to do is take a string
string test = "hello";
and then turn it into an array as such:
string[] testing = { "h", "he", "hel", "hell", "hello" };
is this possible?

Try using Linq:
string test = "hello";
string[] testing = Enumerable
.Range(1, test.Length)
.Select(length => test.Substring(0, length))
.ToArray();
Test:
// h, he, hel, hell, hello
Console.Write(string.Join(", ", testing));

You can also do something like this:
List<string> list = new List<string>();
for(int i = 1; i <= hello.Length; i++) {
list.Add(hello.Substring(0,i));
}
Console.WriteLine(string.Join(", ", list.ToArray()));

I'd recommend Dmitry's LINQ version, but if you want a simple version that uses an array like your original question:
string input = "hello";
string[] output = new string[input.Length];
for( int i = 0; i < test.Length; ++i )
{
output[i] = test.Substring( 0, i + 1 );
}

string test = "hello";
string[] arr = new string[] {test.Substring(0,1), test.Substring(0,2), test.Substring(0,3), test.Substring(0,4), test.Substring(0,5)};

@CDspace The code seems to produce the desired output.

It's giving the output as asked by the OP. And it's correct logically too. Why do you think its wrong?
Yes, you use Linq.
string test = "hello";
List<string> lst = new List<string>();
int charCount = 1;
while (charCount <= test.Length)
{
lst.Add(string.Join("", test.Take(charCount).ToArray()));
charCount++;
}
string[] testing = lst.ToArray();
