I am trying to make a normal form where I can convert Celsius toFahrenheit or viceversa.
private void button1_Click(object sender, EventArgs e)
{
double celsius;
double fahrenheit;
string value;
double finalValue;
bool successCelsius = double.TryParse(textBox1.Text, out celsius);
bool successFahrenheit = double.TryParse(textBox2.Text, out fahrenheit);
if (successCelsius == false)
{
label6.Text = ("ERROR: Please enter a numeric temperature to convert.");
return;
}
else
{
celsius = Convert.ToDouble(textBox1.Text);
finalValue = (celsius * 9) / 5 + 32;
label6.Text = finalValue.ToString();
label6.Text = celsius + " " + "degrees Celsius converts to" + " " + finalValue + " " + "degrees Fahrenheit";
}
if (successFahrenheit == false)
{
label6.Text = ("ERROR: Please enter a numeric temperature to convert.");
return;
}
else
{
fahrenheit = Convert.ToDouble(textBox2.Text);
finalValue = (fahrenheit - 32) * 5 / 9;
value = finalValue.ToString();
label6.Text = fahrenheit + " " + "degrees Fahrenheit converts to" + " " + finalValue + " " + "degrees Celsius";
}
}
Textbox accepted the values and displays to label6. It checks if the entered value is a double or not and then it works.
idk why tryParse isnt working.
Can you help me out? :)
The reason this code doesn't "work" is because of your code flow.
The way the code is structured right now, you have to enter both a celsius and a farenheit value or your code will display an "ERROR". If textbox1 or textbox2 are empty, your code will return false from TryParse. If you follow that logic, this code will execute (if you only enter celsius):
if (successFahrenheit == false)
{
label6.Text = ("ERROR: Please enter a numeric temperature to convert.");
return;
}
UPDATE:
You need to handle both scenarios separately...here is one way that is simple....check for one and do it....otherwise, check the other. THere are a lot of ways to "solve" this problem but this would be one of the easiest.
private void button1_Click(object sender, EventArgs e)
{
double celsius;
double fahrenheit;
string value;
double finalValue;
if (textBox1.Text.Length > 0)
{
bool successCelsius = double.TryParse(textBox1.Text, out celsius);
if (successCelsius == false)
{
label6.Text = ("ERROR: Please enter a numeric temperature to convert.");
return;
}
else
{
celsius = Convert.ToDouble(textBox1.Text);
finalValue = (celsius * 9) / 5 + 32;
label6.Text = finalValue.ToString();
label6.Text = celsius + " " + "degrees Celsius converts to" + " " + finalValue + " " + "degrees Fahrenheit";
}
}
else
{
bool successFahrenheit = double.TryParse(textBox2.Text, out fahrenheit);
if (successFahrenheit == false)
{
label6.Text = ("ERROR: Please enter a numeric temperature to convert.");
return;
}
else
{
fahrenheit = Convert.ToDouble(textBox2.Text);
finalValue = (fahrenheit - 32) * 5 / 9;
value = finalValue.ToString();
label6.Text = fahrenheit + " " + "degrees Fahrenheit converts to" + " " + finalValue + " " + "degrees Celsius";
}
}
}

Input 1550 : output : 5' 1 "
Input 1530 : output : 5' 1/4"
Now, this code works and gives output as needed. I was looking to improvise this code by removing string splitting and other string formatting. Can someone help with inbuilt functions to handle this?

This program bring to random numbers in a decimal way to get sum using ran.next and are stored in the variables sum1a (for the first number) and sum2a (for the second number) and printed in "Suma1.Text"; the operator need to captured the result in the textbox called "Resultado" how has the name "Resultado1" and stored in the variable result1, then is compared with the sum of sum1a and sum2a and stored in total1 to get compared with result1, if total1 match with result1 have to print "Correcto" or "Incorrecto" when there is no match, but sometimes even when the result is correct said that is "Incorrecto".

What can be the reason that sometimes that error happen? I make a stimated and happen 1 of 15 times.
Thank to all for the help but already found a solution, using Math.Round() and "Zero placeholder"
sum1a = ran.Next(10000) / 100.00;
sum2a = ran.Next(10000) / 100.00;
sum1a = Math.Round(sum1a, 2, MidpointRounding.AwayFromZero);
sum2a = Math.Round(sum2a, 2, MidpointRounding.AwayFromZero);
num1a = sum1a.ToString("00.00");
num2a = sum2a.ToString("00.00");
Suma1.Text = " " + num1a + "\r\n +" + num2a + "\r\n¯¯¯¯¯¯¯";
Thanks. uwu
Probably because they don't even equal at all,
Probably not all the numbers were captured in. Compare
The strings instead and use print action to see where the error is at
if (string == string)
{
// Ganastes!
}
if("159.73" == "159.73")
{
// Correct!
}
I have a project where the user can insert a math equation in a single line using the split command. In the first loop the equation get solved correctly and displays the equation with the answer. The problem is with the second loop. It solves the equation and displays the equation with the answer but it also displays the equation from before.
using System;

Console.WriteLine("\nEnter your equation below:");

string[] values = Console.ReadLine().Split(' ');

MBR is declared locally in main. You will not be able to use it outside of the main method in a direct manner.
There are multiple ways to solve this issue, but since your code consists of a single class (no dependency-injection between classes is necessary), two main ways come to mind:
First way:
You can declare it at a higher scope level (in this case, MainClass):
class MainClass
{
double MBR = 0;
//...
This makes the variable accessible to the entire class, including methods in it, which in turn includes ProcessChoice.
Second way:
You can pass it to ProcessChoice as a parameter:
static void ProcessChoice (int c, double MBR) {
//...
and
int choice;
do {
PrintMenu ();
choice = Int32.Parse (Console.ReadLine ());
ProcessChoice(choice, MBR);
} //...
You need to pass the BMR value to your ProcessChoice function:
ProcessChoice (choice, BMR);
static void ProcessChoice (int c, double BMR)
{
....
}
