DecimalSeparator

Hi,

I got 20 textboxes and i want to change the decimal separator to the one they have in their region settings.

This is how i tried it:

foreach (Control textbox in this.Controls)
{
if (textbox is TextBox)
{
int controlIndex = 0;
for (int k = 0; k < 20; k++)
{
string decimalSeparator = System.Globalization.NumberFormatInfo.CurrentInfo.NumberDecimalSeparator;

string input = this._textBox[k].Text;
input = input.Replace(".", decimalSeparator);
input = input.Replace(",", decimalSeparator);

double d;
if (double.TryParse(input, System.Globalization.NumberStyles.Float, System.Globalization.CultureInfo.CurrentCulture, out d))
{
this._tempAnswer = d;
this._answer[controlIndex] = this._tempAnswer;
}
}
}
}

I accept 2 separators which are the dot and the comma and the application should check which one is used in their region settings.

But somehow this is not working. When i press the dot instead of the comma, its marked as wrong answer.

What am i doing wrong

Hi RizwanSharp,

Try this Please:

string decimalSeparator = System.Globalization.NumberFormatInfo.CurrentInfo.NumberDecimalSeparator;
foreach (Control textbox in this.Controls)
{
TextBox currentTextBox = textBox as TextBox;

if(currentTextBox != null)

{
currentTextBox.Text = currentTextBox.Text.Replace(".", decimalSeparator);
currentTextBox.Text = currentTextBox.Text.Replace(",", decimalSeparator);
}
}

It'll replace all the . and commas to appropriate decimel seperators! Now you can add your code to see if its Decimel or string...

I hope this will work!

Best regards,

You should left the .Net framework handle it:

NumberFormatInfo enUS = CultureInfo.GetCultureInfo("en-US").NumberFormat;
NumberFormatInfo deDE = CultureInfo.GetCultureInfo("de-DE").NumberFormat;

string num = "234.56";

double num2= double.Parse(num, enUS);
string num3 = num2.ToString(deDE);

Console.WriteLine(num3);
