Note: Split function has more no of overload method but the below two I found useful. You may found other overloads helpful in your code.
In this post I am going to discuss about two important thing about Split function of String class. Split function of the string class split the string in array of string.
Split function to split string in array
String.Split( char[])
For example
string words = "stringa,stringb, ,stringc,stringd stringe.";
string [] split = words.Split(new Char [] {' ', ','});
Above code create a string array which has
//output split[0]=stringa split[1]=stringb split[2]= split[3]=stringc split[4]=stringd split[5]=stringe
but What If I want to remove empty string from the array when I split string.
Solution to this problem is to make use of second overload method of the the string Split where you can specify the option to remove string. So above code is rewritten as
Overload method with option
String.Split(Char[], StringSplitOptions)
string words = "stringa,stringb, ,stringc,stringd stringe.";
string [] split = words.Split(new Char [] {' ', ','},StringSplitOptions.RemoveEmptyEntries);
Created string array is
//output split[0]=stringa split[1]=stringb split[2]=stringc split[3]=stringd split[4]=stringe
Now consider case where I have to limit no of return string. Consider for example
string a = "key:mykey, Value : test1,test2";
Now I have to get the key:mykey in string 1 and Value : test1,test2 in string 2.
Overload function to split string in limited no. of string
Split(Char[], Int32)
So the code for this is
string a = "key:mykey, Value : test1,test2";
string [] split = words.Split(new Char [] {','},2);
Now the split array have
//output split[0]= "key:mykey"; split[1]= "Value : test1,test2";
Summary
There are also other variable of Split method which you can refer form the msdn link :String.Split. But I fond above two more useful than others.
