This is the simple example of throw Statement.
In this program here we use the Throw statement which throws the exception if the user will enter the value which meets the condition which has been set for the throw block.
There are mainly three block on which this system works.
1) Throw : This is the initial stage of the program.
In this block the program will throw the exception error.
2) Try : This is the second stage of the program.
In this block the program will print the statement which define by the programmer, if the condition will be will be true.
3) Catch : This is the final block of the program.
In this block the program will print the error and finally it will stop the execution of the program.
This statement is use to prevent the program from the shutdown of a program, whether the condition will be true than it will give error in the runtime.
NOTE: There also a "Finally" block which has been design to give output whether the upper blocks will be true or false by default it will execute, it did not depend on any other block as we seen in the previous blocks.
ENJOY CODING!!!

}
catch (Exception e)
{
Console.WriteLine("Error : " + e.ToString());
}
Console.ReadLine();
}
}
}
Output :
If the condition will be false the output will be as follows :
