How to fix this in C#: main.cs(18,5): warning CS0642: Possible mistaken empty statement

I am working on a BMI calculation assignment using the If-else statements. I get an error

CS1525 unexpected symbol 'else'

and warning

CS0642: Possible mistaken empty statement

This is a BMI calculation in C#

bmi = (weight * 703) / height^2;

if (bmi < 18.5);
{
    Console.WriteLine("Underweight"); 

else if (bmi <= 25)
    Console.WriteLine("Optimal"); 

else if (bmi > 25);
    Console.WriteLine("Overweight");
}

Mono C# compiler version 4.6.2.0

mcs -out:main.exe main.cs

main.cs(20,5): warning CS0642: Possible mistaken empty statement
main.cs(23,6): error CS1525: Unexpected symbol `else'
main.cs(27,13): warning CS0642: Possible mistaken empty statement
Compilation failed: 1 error(s), 2 warnings
compiler exit status 1

Can you please update the code as below and try -

bmi = (weight * 703) / Math.Pow(height,2);

if (bmi < 18.5) Console.WriteLine("Underweight");

else if (bmi <= 25) Console.WriteLine("Optimal");

else if (bmi > 25) Console.WriteLine("Overweight");

I dont have Mono compiler, but try this:

bmi = (weight * 703) / Math.Pow(height,2);

if (bmi < 18.5)
{
  Console.WriteLine("Underweight"); 
}
else if (bmi <= 25)
{
  Console.WriteLine("Optimal");
}
else if (bmi > 25)
{
  Console.WriteLine("Overweight");
}

You have a semicolon right in front of the if statement. In languages like C or C++ it would mean that the if statement would do nothing but C# treats it as an error. Because the code inside the curly braces does not belong to the if statement, because of the semicolon, the else keyword can't be there.

Edit

Also, your else ifs should be after closing the curly braces
