C# has a total of 10 overload methods.

 

 

Most of the developers adopt the below approach.

string str = "Akshay|Patel";
Stopwatch s1 = new Stopwatch();
s1.Start();
string[] temp1 = str.Split('|');
Console.WriteLine(s1.ElapsedTicks.ToString());

Let’s change the approach; i.e., rather than passing the character directly, let us create an array of characters and pass them as array elements.

Stopwatch s2 = new Stopwatch();
s2.Start();
string[] temp = str.Split(new char[] {
    '|'
});
Console.WriteLine(s2.ElapsedTicks.ToString());

Run the application and compare the execution time.

 

The result suggests adopting the second approach to save the execution time.
