how can I separate an array in smaller arrays?
string[] str = new string[145]
I want two arrays for this; like
string[] str1 = new string[99];
string[] str2 = new string[46];
how can I do this from the source of str?
1- Then I want to put together the arrays into List all together but there is only add item? no add items? or any other way to make the string[145] array again..
Simplest way, using LINQ:
string[] str1 = str.Take(99).ToArray();
string[] str2 = str.Skip(99).ToArray();
Putting them back together:
str = str1.Concat(str2).ToArray();
These won't be hugely efficient, but they're extremely simple :) If you need more efficiency, Array.Copy is probably the way to go... but it would take a little bit more effort to get right.
You can use Array.Copy to get some of the items from the source array to another array.
string[] str1 = new string[99];
string[] str2 = new string[46];
Array.Copy(str, 0, str1, 0, 99);
Array.Copy(str, 99, str2, 0, 46);
You can use the same to copy them back.
To create a list, use the List<T>.AddRange method:
var array = new string[145];
var list = new List<string>();
list.AddRange(array);
