I am creating a program in C# language to perform conversions I am currently implementing the binary -> decimal and decimal -> binary.
How can I do the conversion if user type large numbers as I should treat this?
Buttons
private void Btn_Decimal_Binario_Click(object sender, EventArgs e)
{
try
{
//Armazena o valor em decimal, convertendo o texto em tipo inteiro
int ValorDecimal = int.Parse(txt_decimal.Text);
//Realiza a chamada do metodo e armazena resultado na textbox
txtBinario.Text = DecimalParaBinario(ValorDecimal);
}
catch (Exception)
{
MessageBox.Show("Verifique o preenchimento das informações no formulario ! ", "Alerta !", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
private void Btn_Binario_Decimal_Click(object sender, EventArgs e)
{
try
{
//Armazena o valor em binario,convertendo o texto em tipo inteiro
int ValorBinario = int.Parse(txt_Binario_2.Text);
//Realiza a chamada do metodo e armazena resultado na textbox
txt_decimal_2.Text = BinarioParaDecimal(ValorBinario);
}
catch (Exception)
{
MessageBox.Show("Verifique o preenchimento das informações no formulario ! ", "Alerta !", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
Conversions
static string DecimalParaBinario(int n)
{
int resto;
string result = string.Empty;
while (n > 0)
{
resto = n % 2;
n /= 2;
result = resto.ToString() + result;
}
return result.ToString();
}
static string BinarioParaDecimal(int n)
{
//Conversão Binario em Decimal
int bin, dec = 0, resto, basenum = 1;
bin = n;
while (n > 0)
{
resto = n % 10;
dec = dec + resto * basenum;
basenum = basenum * 2;
n = n / 10;
}
return dec.ToString();
}
What is "big numbers"?

How should you treat ? declare a variable of large number.. because you declare
int
for Valordecimal???? is not a Value valueDecimal

Hello @Matheusgonçalves welcome to Stackoverflow. Could you give us an example of these "big numbers"?
– Danilo Pádua
For example even putting in Decimal if I type for example 1231231231231231231231231232312312312 it throws error
