How to split by multiple strings in C#

My Question consists of how might i split a string like this:
""List of devices attached\r\n9887bc314\tdevice\r\n12n1n2nj1jn2
\tdevice\r\n\r\n"
Into:
[n9887bc314,n12n1n2nj1jn2]
I have tried this but it throws the error "Argument 1: cannot convert from 'string' to 'char'"
string[] delimiterChars = new string[] {"\\","r","n","tdevice"};
string y = output.Substring(z+1);
string[] words;
words = y.Split(delimiterChars, StringSplitOptions.None);
I'm wondering if i'm doing something wrong because i'm quite new at c#.
Thanks A Lot

First of all String.Split accept strings[] as delimiters
Here is my code, hope it will helps:
string input = "List of devices attached\r\n9887bc314\tdevice\r\n12n1n2nj1jn2\tdevice\r\n\r\n";
string[] delimiterChars = {
"\r\n",
"\tdevice",
"List of devices attached"
};
var words = input.Split(delimiterChars, StringSplitOptions.RemoveEmptyEntries);
foreach (var word in words)
{
Console.WriteLine(word);
}

Split the whole string by the word device and then remove the tabs and new lines from them. Here is how:
var wholeString = "List of devices attached\r\n9887bc314\tdevice\r\n12n1n2nj1jn2\tdevice\r\n\r\n";
var splits = wholeString.Split(new[] { "device" }, StringSplitOptions.RemoveEmptyEntries);
var device1 = splits[1].Substring(splits[1].IndexOf("\n") + 1).Replace("\t", "");
var device2 = splits[2].Substring(splits[2].IndexOf("\n") + 1).Replace("\t", "");

I've been doing a first aproach and it works, it might help:
I splited the input looking for "/tdevice" and then cleaned everyting before /r/n including the /r/n itself. It did the job and should work with your adb output.
EDIT:
I've refactored my answer to consider #LANimal answer (split using all delimiters) and I tried this code and works. (note the # usage)
static void Main(string[] args)
{
var inputString = #"List of devices attached\r\n9887bc314\tdevice\r\n12n1n2nj1jn2\tdevice\r\n\r\n";
string[] delimiters = {
#"\r\n",
#"\tdevice",
#"List of devices attached"
};
var chunks = inputString.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
string result = "[";
for (int i = 0; i < chunks.Length; i++)
{
result += chunks[i] + ",";
}
result = result.Remove(result.Length - 1);
result += "]";
Console.WriteLine(result);
Console.ReadLine();
}
I hope it helps,

You could do:
string str = #"List of devices attached\r\n9887bc314\tdevice\r\n12n1n2nj1jn2\tdevice\r\n\r\n";
string[] lines = str.Split(new[] { #"\r\n" }, StringSplitOptions.None);
string firstDevice = lines[1].Replace(#"\tdevice", "");
string secondDevice = lines[2].Replace(#"\tdevice", "");

Retrieving string from a string which is in between two String?

i have a string Like
"Hello i want to go."
my code give "want to go."
but i need string between " i " and " to " how can i get this? my code is as below.
string[] words = Regex.Split("Hello i want to go.", " i ");
string respons = words[1];

string input = "Hello i want to go.";
Regex regex = new Regex(#".*\s[Ii]{1}\s(\w*)\sto\s.*");
Match match = regex.Match(input);
string result = string.Empty;
if (match.Success)
{
result = match.Groups[1].Value;
}
This regex will match any 'word' between 'i' (not case sensitive) and 'to'.
EDIT: changed ...to.* => to\s.* as suggested in the comments.

string input = "Hello I want to go.";
string result = input.Split(" ")[2];
If you want the word after the "i" then:
string result = input.Split(" i ")[1].Split(" ")[0];

Use
string s = "Hello i want to go.";
string[] words = s.split(' ');
string response = wor

just do it with one simple line of code
var word = "Hello i want to go.".Split(' ')[2];
//Returns the word "want"

string input = "Hello I want to go.";
string[] sentenceArray = input.Split(' ');
string required = sentenceArray[2];

Here's an example using Regex which gives you the index of each occurrence of "want":
string str = "Hello i want to go. Hello i want to go. Hello i want to go.";
Match match = Regex.Match(str, "want");
while(match.Success){
Console.WriteLine(string.Format("Index: {0}", match.Index));
match = match.NextMatch();
}

Nowhere does it say Regex...
string result = input.Split.Skip(2).Take(1).First()

it's work
public static string Between(this string src, string findfrom, string findto)
{
int start = src.IndexOf(findfrom);
int to = src.IndexOf(findto, start + findfrom.Length);
if (start < 0 || to < 0) return "";
string s = src.Substring(
start + findfrom.Length,
to - start - findfrom.Length);
return s;
}
and it can be called as
string respons = Between("Hello i want to go."," i "," to ");
it return want

Find Chr(13) in a text and split them in C#

I have written two lines of code below in vb6. The code is :
d = InStr(s, data1, Chr(13), 1) ' Fine 13 keycode(Enter) form a text data.
sSplit2 = Split(g, Chr(32)) ' Split with 13 Keycode(Enter)
But I can't write above code in C#. Please help me out. How can I write the above code in C#.

I believe you are looking for string.Split:
string str = "Test string" + (char)13 + "some other string";
string[] splitted = str.Split((char)13);
Or you can use:
string[] splitted = str.Split('\r');
For the above you will get two strings in your splitted array.

the equivalnt code for sSplit2 = Split(g, Chr(32)) is
string[] sSplit2 = g.Split('\n');

int index = sourceStr.IndexOf((char)13);
String[] splittArr = sourceStr.Split((char)13);

const char CarriageReturn = (char)13;
string testString = "This is a test " + CarriageReturn + " string.";
//find first occurence of CarriageReturn
int index = testString.IndexOf(CarriageReturn);
//split according to CarriageReturn
string[] split = testString.Split(CarriageReturn);
If you want to encapsulate the carriage return depending on whether you are running in a unix or non unix environment you can use Environment.NewLine . See http://msdn.microsoft.com/en-us/library/system.environment.newline(v=vs.100).aspx .
string testString2 = "This is a test " + Environment.NewLine + " string.";
//find first occurence of Environment.NewLine
int index2 = testString2.IndexOf(Environment.NewLine);
//split according to Environment.NewLine
string[] split2 = testString2.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);

How to split string using Substring

I have a string like '/Test1/Test2', and i need to take Test2 separated from the same. How can i do that in c# ?

Try this:
string toSplit= "/Test1/Test2";
toSplit.Split('/');
or
toSplit.Split(new [] {'/'}, System.StringSplitOptions.RemoveEmptyEntries);
to split, the latter will remove the empty string.
Adding .Last() will get you the last item.
e.g.
toSplit.Split('/').Last();

Use .Split().
string foo = "/Test1/Test2";
string extractedString = foo.Split('/').Last(); // Result Test2
This site have quite a few examples of splitting strings in C#. It's worth a read.

Using .Split and a little bit of LINQ, you could do the following
string str = "/Test1/Test2";
string desiredValue = str.Split('/').Last();
Otherwise you could do
string str = "/Test1/Test2";
string desiredValue = str;
if(str.Contains("/"))
desiredValue = str.Substring(str.LastIndexOf("/") + 1);
Thanks Binary Worrier, forgot that you'd want to drop the '/', darn fenceposts

string[] arr = string1.split('/');
string result = arr[arr.length - 1];

string [] split = words.Split('/');
This will give you an array split that will contain "", "Test1" and "Test2".

If you just want the Test2 portion, try this:
string fullTest = "/Test1/Test2";
string test2 = test.Split('/').ElementAt(1); //This will grab the second element.

string inputString = "/Test1/Test2";
string[] stringSeparators = new string[] { "/Test1/"};
string[] result;
result = inputString.Split(stringSeparators,
StringSplitOptions.RemoveEmptyEntries);
foreach (string s in result)
{
Console.Write("{0}",s);
}
OUTPUT : Test2

How do I split a string into an array?

I want to split a string into an array. The string is as follows:
:hello:mr.zoghal:
I would like to split it as follows:
hello mr.zoghal
I tried ...
string[] split = string.Split(new Char[] {':'});
and now I want to have:
string something = hello ;
string something1 = mr.zoghal;
How can I accomplish this?

String myString = ":hello:mr.zoghal:";
string[] split = myString.Split(':');
string newString = string.Empty;
foreach(String s in split) {
newString += "something = " + s + "; ";
}
Your output would be:
something = hello; something = mr.zoghal;

For your original request:
string myString = ":hello:mr.zoghal:";
string[] split = myString.Split(new[] { ':' }, StringSplitOptions.RemoveEmptyEntries);
var somethings = split.Select(s => String.Format("something = {0};", s));
Console.WriteLine(String.Join("\n", somethings.ToArray()));
This will produce
something = hello;
something = mr.zoghal;
in accordance to your request.
Also, the line
string[] split = string.Split(new Char[] {':'});
is not legal C#. String.Split is an instance-level method whereas your current code is either trying to invoke Split on an instance named string (not legal as "string" is a reserved keyword) or is trying to invoke a static method named Split on the class String (there is no such method).
Edit: It isn't exactly clear what you are asking. But I think that this will give you what you want:
string myString = ":hello:mr.zoghal:";
string[] split = myString.Split(new[] { ':' }, StringSplitOptions.RemoveEmptyEntries);
string something = split[0];
string something1 = split[1];
Now you will have
something == "hello"
and
something1 == "mr.zoghal"
both evaluate as true. Is this what you are looking for?

It is much easier than that. There is already an option.
string mystring = ":hello:mr.zoghal:";
string[] split = mystring.Split(new char[] {':'}, StringSplitOptions.RemoveEmptyEntries);
