Hi, im sorry if this is the wrong place to post but its the only resource available to me at the time. While working on a project for school I have encountered an issue with getting my method to work.
My task is to create a single method that will carry out the arithmetic in each one of those if statements. I watched the video made by Brackeys about methods in c# however im still clueless on how to make this work.
Instead of this:
if (operator1 == "+")
{
decimal result = operand1 + operand2;
txtResult.Text = result.ToString();
}
else if (operator1 == "-")
{
decimal result = operand1 - operand2;
txtResult.Text = result.ToString();
}
I should have this:
if (operator1 == "+")
{
//run method "calculate"
}
else if (operator1 == "-")
{
//run method "calculate"
}
Below is a concept I have tried but was unsuccessful, any suggestions?
private static Boolean Calculate(this string logic, int operand1, int operand2)
{
switch (logic)
{
case "-": return operand1 - operand2;
case "+": return operand1 + operand2;
case "/": return operand1 / operand2;
case "*": return operand1 * operand2;
default: throw new Exception("invalid logic");
}
}
For reference, this is the requirement in my project:
“Code a private method named Calculate that performs the requested operation and returns a decimal value. You will need two decimal variables for each operand and a string variable for the operator (to be performed on the 2 values).”
