I've looked around but can't find anything that has helped me. I have the following issue - I have a string array that contains:
[0] = "2.4 kWh @ 105.00 c/kWh"
where [0] is the index of the array. I need to split it by a space, so that I can have several smaller arrays. So it should look like:
[0] will contain 2.4
[1] will contain kWh
[2] will contain @
[3] will contain 105.00
[4] will contain c/mWh
I've tried several solutions but none works. Any assistance would be highly appreciated.
string s = "2.4 kWh @ 105.00 c/kWh";
string[] words = s.Split(new char [] {' '}); // Split string on spaces.
foreach (string word in words)
{
Console.WriteLine(word);
}
Then you can get the console output as
2.4
kWh
@
105.00
c/mWh
We'll use string[] strings = new[] { "2.4 kWh @ 105.00 c/kWh", "this is a test" }; as an example of your array.
This is how you can put it all into one array. I've kept it as an IEnumerable<T> to keep that benefit, but feel free to append .ToArray().
public IEnumerable<string> SplitAll(IEnumerable<string> collection)
{
return collection.SelectMany(c => c.Split(' '));
}
Here, this would evaluate to { "2.4", "kWh", "@", "105.00", "c/kWh", "this", "is", "a", "test" }.
Or if I'm misunderstanding you and you actually do want an array of arrays,
public IEnumerable<string[]> SplitAll(IEnumerable<string> collection)
{
return collection.Select(c => c.Split(' '));
}
Here, { { "2.4", "kWh", "@", "105.00", "c/kWh" }, { "this", "is", "a", "test" } }.
Or if I'm totally misunderstanding you and you just want to split the one string, that's even easier, and I've already shown it, but you can use string.Split.
This will give you a two dimensional array (array of string arrays):
var newArr = strArr.Select(s => s.Split(' ').ToArray()).ToArray();
for example:
string[] strArr = new string[] { "2.4 kWh @ 105.00 c/kWh", "Hello, world" };
var newArr = strArr.Select(s => s.Split(' ').ToArray()).ToArray();
for (int i = 0; i < newArr.Length; i++)
{
for(int j = 0; j < newArr[i].Length; j++)
Console.WriteLine(newArr[i][j]);
Console.WriteLine();
}
// 2.4
// c/kWh
// @
// 105.00
// kWh
//
// Hello,
// world
