Loop through comma delimited string, split into multiple arrays?

Question

I have a string coming in the format:

div, v6571, 0, div, v8173, 300, p, v1832, 400

I want to split this string into multiple arrays, for the example above I would need 3 arrays, such that the format would be like this:

item[0] -> div
item[1] -> v6571
item[2] -> 0

I know that I can just do a .Split(',') on the string and put it into an array, but that's one big array. For the string example above I would need 3 arrays with the structure provided above. Just getting a bit confused on the iteration over the string!

Thanks!

I'm not sure exactly what you're looking for, but to turn the above into three separate arrays, I'd do something like:

var primeArray = yourString.Split(,);
List<string[]> arrays = new List<string[]>();
for(int i = 0; i < primeArray.Length; i += 3)
{
  var first = primeArray[i];
  var second = primeArray[i+1];
  var third = primeArray[i+2];

  arrays.Add(new string[] {first, second, third});
}

Then you can iterate through your list of string arrays and do whatever.

This does assume that all of your string arrays will always be three strings long- if not, you'll need to do a foreach on that primeArray and marshal your arrays more manually.

Here's the exact code I used. Note that it doesn't really change anything from my original non-compiled version:

var stringToSplit = "div, v6571, 0, div, v8173, 300, p, v1832, 400";
List<string[]> arrays = new List<string[]>();
var primeArray = stringToSplit.Split(',');
for (int i = 0; i < primeArray.Length; i += 3)
{
   var first = primeArray[i];
   var second = primeArray[i + 1];
   var third = primeArray[i + 2];
   arrays.Add(new string[] { first, second, third });
}

When I check this in debug, it does have all three expected arrays.
