Hello Abaigail,

Try the code below and you can get results.
string[] myarr = new[] { "a", "b", "c" };
List resultarray = new List();
string strVal = "";
            for (int i = 0; i < myarr.Length; i++)
            {
                strVal = strVal + myarr[i].ToString();
                resultarray.Add(strVal);
            }

Try this code,
string[] arr = new[] { "a", "b", "c" };
List<string> list = new List<string>(arr);

To add these items to a list, consider:
string[] myarray = new string[] { "a", "b", "c" };
List<string> results = new List<string>();
for (int i = 0; i < myarray.Length; i++)
{
   string result = "";
   for (int j = 0; j <= i; j++)
   {
      result += myarray[j];
   }
   results.Add(result);
}
