trim c# example

Example 1: c# remove spaces from string

string str = "This is a test";
str = str.Replace(" ", String.Empty);
// Output: Thisisatest

Example 2: c# shorten an method

//Full defenition
bool IsEven(int num)
{
  return num % 2 == 0;
}

//Can be rewritten as:
bool isEven(int num) => num % 2 == 0;

//This can only work with one expression methods

Example 3: c# trim string

string hello = " hello world ";
hello.Trim();
