The while and do-while statements in C#
While Statement:
A while statement conditionally executes a statement zero or more times – as long as a boolean test is true.
public class Employee
{
public void FindEmployee(string[] arrNames, string name)
{
int i = 0;
while (arrNames[i] != name)
{
if (i > arrNames.Length)
return;
Console.WriteLine("Wrong Employee Details");
i = i + 1;
}
Console.ReadLine();
}
}
As shown above FindEmployee() method displays wrong Employee details.
do-while Statement:
A do statement conditionally executes a statement one or more times.
public class Employee
{
public void FindEmployee(string[] arrNames, string name)
{
int i = 0;
do
{
if (i > arrNames.Length)
return;
Console.WriteLine("Wrong Employee Details");
i = i + 1;
}
while (arrNames[i] != name);
Console.ReadLine();
}
}
