Hi,

How do i convert a string to float/double if the decimal-seperator doesn't
follow the local language settings ??

Eg.
string s = load a value from a file - "1234,12";
float f = float.Parse(s);

This will fail because my PC expect a dot - not a comma.

Peter,

You can create a NumberFormatInfo instance and set the
NumberGroupSeparator to the comma character, and then pass it to the Parse
method, and it should parse it correctly.

Hope this helps.

Click to expand...

You can specify local explicit:

float f = float.Parse(s, new CultureInfo("da-DK", false));

Hi Peter,

Nicholas has pointed out the right direction.

We could use NumberFormatInfo to solve this problem, i.e. create a
NumberFormatInfo instance and set its NumberDecimalSeparator property to
","(perhaps Nicholas miswrote the NumberDecimalSeparator to
NumberGroupSeparator).

The following is a sample.

NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = ",";
float f = float.Parse("1234,12", nfi);

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,

Thank you all for your comments.

I will try the sample from Linda:

NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = ",";
float f = float.Parse("1234,12", nfi);
