split a string

Ankit Shukla

Hello;

Suppose I have a string like:

"Ministry Of Labour and Employment"

I need to split string after 20 characters, then sub strings are "Ministry Of Labour a" and "nd Employment" . How can I convert it in "Ministry Of Labour" and "and Employment"

Thanks in advance.

Hi Ankit,

Are you sure? I just re-tested my code, it gives me proper results.

Here is evidence: http://prntscr.com/9esafc

I think the website reply has messed up my code, so here is a better format:

Assuming the format of the string will be constant(ie five words if we split with spaces),you can use string.split and then join with the desired indices to achieve desired output.it will be

string str = "Ministry Of Labour and Employment";
string returnstr,returnstr1 ;
string[] arr1 = new string[10];
arr1=str.Split();
returnstr = arr1[0] + " " + arr1[1] + " " + arr1[2];
returnstr1 = arr1[3] + " " + arr1[4] ;

output : returnstr = Ministry Of Labour and returnstr1 = and Employment

Anyways this works like charm for Five Words Seperated by Four Spaces but this method fails if the string format is changed.just wanted to convey the simplest method possible.

You can use the below code for your reference.

string s = "this is only some example okay";
string[] strArr = s.Split(' ');
int ires = 0;
string strText = "";
foreach (string str in strArr)
{
ires += str.Length;
if (ires <= 20)
{
strText += " " + str;
}
}
strText = strText.Trim(' ');
Console.WriteLine(strText);

O/P:
this is only some

The only full words, not the in mid words.

{
string name = "Ministry Of Labour and Employment";

string str1 = name.Substring(0, 19);
string str2 = " " + name.Substring(19);

Console.WriteLine(str1);
Console.WriteLine(str2);

Console.ReadKey();
}
}
}
//Ministry Of Labour
// and Employment

you're right! I had one word too much - a logical error! I only changed the while block:

while (true)
{
char c = temp.ElementAt(number++);
if (c == ' ') break;
neu = neu.Substring(0, neu.Length-1);
}

Hi Ankit

I think you talking about specific string. I have written code as per my understanding of your requirement. Please look it.

string str = "Ministry Of Labour and Employment";
var subStr = str.Substring(0, 20);
string newStr = subStr.Substring(0, subStr.Length - 1);
string splitStr = str.Substring(newStr.Length - 1);
Console.WriteLine(newStr.Trim());
Console.WriteLine(splitStr.Trim());

Hello Mate, Try like

string str = "Ministry Of Labour and Employment";
string sub = str.Substring(0, 19);
string sub1 = str.Substring(19, str.Length-19);

Hello Matthias Sir;

I am trying your code. But it did not show remaining string.

Hello Raghav Sir,

I tried your code, But it returns "Ministry " and "Of Labour and Employment".
Matthias10y ago
Then you can use the following code:

int number = 20;
string s = "this is only some example okay";
char[] temp = s.ToCharArray();
string neu = s.Substring(0, number);
while (true)
{
   char c = temp.ElementAt(number++);
   neu += c;
   if (c == ' ') break;
}

I think he's trying to split any given string after 20 characters. Not sure if .Split will be very efficient for that.
Matthias10y ago
- firstly you can use the method Split with argument ' '
- now you have got an array with the single words
- then you can use a while-loop for join the words - termination condition is length=20
- now you have got the desired string

I think this will be useful to you. This algorithm will split strings with 20 characters. Then it will check if the last word in the first set of a split is a complete word. So in "Ministry of Labour a", it checks if after "a" at the end there is a space. If there is a space, then it will assume it is a complete word, else if it is not, it will find the last complete word. This fixes the problem (I tested the code)

namespace csharpcorn
{
   class Program
   {
      static void Main(string[] args)
      {
         string someWord = "Ministry Of Labour and Employment";
         if(!someWord.Substring(20,1).Equals(" "))
         {
            for(int i = 20; i > 0; i--)
            {
               if(someWord.Substring(i, 1).Equals(" "))
               {
                 Console.WriteLine(someWord.Substring(0, i)); //"Ministry of Labour"
                 Console.WriteLine(someWord.Substring(i, someWord.Length - i)); //"and Employment"
                 break;
               }
            }
         }
         else
         {
            Console.WriteLine(someWord.Substring(0, 20));
         }
         Console.ReadKey();
     }
}
}

I'm little confused about requirement? what you want to achieve exactly?

```
static IEnumerable Split(string str, int chunkSize) { return Enumerable.Range(0, str.Length / chunkSize) .Select(i => str.Substring(i * chunkSize, chunkSize)); }
```
Please note that additional code might be required to gracefully handle edge cases (null or empty input string, chunkSize == 0, input string length not divisible by chunkSize, etc.). The original question doesn't specify any requirements for these edge cases and in real life the requirements might vary so they are out of scope of this answer.
