Float TryParse not working as expected from string

I tried several examples/ways of doing it and no expected result.

I store in a string 

// Contains in my case "EUR849.00" so I want to get only the proper number.
string properPrice = price[0].Substring(3);

Now, I try to parse this string 849.00into float and I expect to have this format 849,00.

I tried several examples (specific invariant culture, replacing the . with , and then parsing using float.Parse but it doesn't work).

The way I'm doing it is : 

float.TryParse(properPrice, NumberStyles.Any, CultureInfo.InvariantCulture, out floatPrice);

The result is 84900.0. Any suggestions? Tx.

You only need specify the culture when parsing when the format of the string is not using the current culture's formatting. So if your culture uses a decimal instead of a comma you don't need to specify it.

If your current culture uses decimals, then you need to specify a culture that uses commas, when you write out the value. In the example below I have picked the German culture, which uses commas.

Also, it looks like you are dealing with currency, so you should decimal instead of float. http://msdn.microsoft.com/en-us/library/364x0z75.aspx

string val = "EUR849.00";
decimal num = Decimal.Parse(val.Substring(3));

string expected = num.ToString(CultureInfo.GetCultureInfo("de-DE"));

Console.WriteLine(expected);

UPDATE With a float:

string val = "EUR849.00";
float num = Single.Parse(val.Substring(3));

string expected = num.ToString("0.00", CultureInfo.GetCultureInfo("de-DE"));

Console.WriteLine(expected);
