Question

How to format string with number value?

Tim Kohlmeyer 0

Hey Community,

I have a string which I want to transform from:

5000000,00

to

5.000.000,00

I hope that you can help me. The programming language is C#. I need a replacement which is dynamically because the string can have values like 5,00, 1.000,00, 1.000.000.000,00 etc.....

Best regards

For this you can use a format string, see

Standard numeric format strings

Custom numeric format strings

e.g. N2 for numeric with 2 decimals.

Thank you for you answer. The ToString("N1", CultureInfo.InvariantCulture) doesn't work. Visual Studio marked it as an error for me. The number is already converted in string so i have the following code which I try out:

label1.Text = myString.ToString("N1", CultureInfo.InvariantCulture);

The string can be converted to number before formatting, for example:

string s = "5000000,00";
var c = CultureInfo.GetCultureInfo( "de" );
string result = decimal.Parse( s, c ).ToString( "#,##0.00", c );
// Result: 5.000.000,00

Use the appropriate culture.
