Split string var

Let's say I have this string var:

string strData = "1|2|3|4||a|b|c|d"

Then, I make a Split:

string[] strNumbers = strData.Split("||"); //something like this, I know It's not this simple

I need two separate parts, each one containing this:

//strNumbers -> {"1","2","3","4"},{"a","b","c","d"}

So that after that, I coul开发者_如何学JAVAd do this:

string[] strNumArray = strNumbers[0].Split('|');
//strNumArray -> '1', '2', '3', '4'

And same with the other part (letters).

Is it possible? to make this double split with the same character, but the first time the character is repeated twice?.

Thanks.

PD. I'm using C#.

It'll work fine, your syntax is just off.

So first, your declarations are off. You want the [] on the type, not the name.

Second, on String.Split, there is an overload that takes in a string array and a StringSplitOptions. Just trying to do "||" will call the param char overload, which is invalid.

So try this:

string strData = "1|2|3|4||a|b|c|d";
string[] strNumbers = strData.Split(new[] {"||"}, StringSplitOptions.None);
string[] strNumArray = strNumbers[0].Split('|');

You can change the StringSplitOptions to RemoveEmptyEntries if you wanted.

in .net 3.5:

string strData = "1|2|3|4||a|b|c|d";  
var s1 = strData.Split(new string[] { "||" }, StringSplitOptions.None);
var numbers = s1[0].Split('|');
var letters = s1[1].Split('|');

    Dim s As String = "1|2|3|4|5|6|7||a|b|c|d|e|f"
    Dim nums() As String = s.Split(New String() {"||"}, StringSplitOptions.None)(0).Split("|")
    Dim strs() As String = s.Split(New String() {"||"}, StringSplitOptions.None)(1).Split("|")
