I am taking input from a text box. I've saved the input digits from text box to an array like this:
char[] _array = textBox1.Text.ToCharArray(0, textBox1.Text.Length);
Now I want to convert the array to an int array because I want to perform mathematical operations on each index of the array.
How can I achieve the goal? Thanks.
You could do it with LINQ if you just want the character code of each char.
var intArrayOfText = "some text I wrote".ToCharArray().Select(x => (int)x);
or
var intArrayOfText = someTextBox.Text.ToCharArray().Select(x => (int)x);
If each character expected to be a digit, you can parse it to an int:
List<int> listOfInt = new List<int>();
_array.ToList().ForEach(v => listOfInt.Add(int.Parse(v.ToString())));
int[] _intArray = listOfInt.ToArray();
Character code value:
List<int> listOfCharValue = new List<int>();
_array.ToList().ForEach(v => listOfCharValue.Add((int)v));
int[] _charValueArray = listOfCharValue.ToArray();
You need to handle exceptions.
Assuming what I asked in my comment is true:
string[] ints = { "1", "2", "3" };
var str = ints.Select(i => int.Parse(i));
However, the above will work only if you have already validated that your input from the text box is numeric.
I've solved my problem. I used list to accomplish the task.
I stored each array index at the relative index of the list after converting each index value to int.
Using list seems more convenient way to me. :)
Thanks to all of you.
charto its character code?
