C# string handling

We have lots of string handling functions in C#.net. We are just going to see some basic


functions.


C# string Split() - Splitting a string to an Array


The split() can be used to Split an entire string in to an string array. This will be


done using this split method. This can be used when you need long strings to be splitted


to seperate string objects.


---------------------------------------------


string mString = "This is to show Splitting in strings";
string[] mArr = mString.Split(' ');


---------------------------------------------


Here in the above code we have a string named mString and we have assigned a string to


it. Now check the second line of it. We have created an String Array to store the values


that gets Splitted.
mString.Split(' ') method splits the Entire string into an array. We have given a white


space as the argument for the Split method for the string. This will allow it to split


the string whenever it sees a white space inside the string.


Now, if you need to get the Splitted values of the string you must have to fetch the


entire items of the Array mArr using some loops.




C# string.Join() - Joining an Array as a String


The Join() method can be used to join an Array to a single String. If we have an array


to be used as a single string you can use this string.Join() method.
Let's see an example for it


---------------------------------------------


string joinedString = string.Join("-", mArr);


//Here the JoinedString variables value will be
// "This-is-to-show-Splitting-in-strings"


---------------------------------------------


In the above code in the Join function we have two overloads mainly
string.Join("String Separator","The array to Join");
Here in the above we have set the Separator as "-"(hyphen). So it will attach each Array


element with this "-". Like wise we can join the Strings in any way we like.
