converting a string array to int[]

hi there,I have my array

string[]myNumber=new string[]{"1,2,5,4,6,"};

how can i convert above array to:

int[]number=new int[]{1,2,5,4,6,};

Note that i have tried to use myNumbers.CopyTo(number,0),it failed with a system warning that the two array must be of the same type and size.

Or is there any other way i can use, like List<> to achieve this function.

My aim is to convert the string array to int[]

Thanks in advance
Yours Martin

Solution 2

Try

string[] myNumber=new string[]{"1,2,5,4,6,"};
string[] arr = String.Split(myNumber[0]);
int[] intarr = new intarr[arr.count];
foreach(string str in arr)
{
   intarr[count++] = Convert.ToInt(str);
}

your method ignores the fact that there could be more items in the array. If there is only going to be the one item the OP might as well be using a single string and not an array

Solution 3

public int[] StringToInt(string[] arr)
{
int i;
List<int> result = new List<int>();
for(int x=0;x < arr.Length; x++)
{
    if (int.TryParse(arr[x], out i))
        result.Add(i);
}
return result.ToArray();
}
</int></int>

This will be just a little safer in case an invalid string is parsed in.

So, you think his array is still fine for what hes trying to do, and this will work... ok, send his array to this method and let us know the result.

dominic - I think your method is fine by the way... for an array of the type I mention... good one. :)

Solution 1

First, the way you intialized your string array, you created one string of "1,2,3,4,5" ... not five individual strings. :)

But... here is one way to do it...

C#

string[] strValues = new string[] { "1", "2", "3", "4", "5" };
int[] intValues = strValues.Select(val => Convert.ToInt32(val)).ToArray();

technically the OP's array is still fine
