C# String format: escape a dot

Question

I have a line of code, something like:

mbar.HealthLabel.text = String.Format("{0:0.0}", _hp);

Output is: 2.25 for example. Is it possible to escape a dot from the output string view with String.Format function ?

For. ex. 225,

To make my question more clear, I need the same effect like:

Math.Floor(_hp * 100).ToString();

But need to do it by String.Format template.. Thanks.

Answer 1

Simply you can do it this way

double value = 1.25;

var stringValue = string.Format("{0:0}", value * 100, CultureInfo.InvariantCulture); //125

EDIT: More general solution would be to Replace the dot with empty string as stated in the comments.

double value = 1.25;

var stringValue = value.ToString(CultureInfo.InvariantCulture).Replace(".",string.Empty);

EDIT2: Also there is another general idea that do not use Replace function (but also it does not use the String.Format)

var stringValue = string.Join("", value.ToString().Where(char.IsDigit));

Also another similar idea:

var stringValue = new string(value.ToString().Where(char.IsDigit).ToArray());
