How to measure the size of a string

Question

windows app store how to measure the size of a string?

string str = "Hello word windows app store";

Answer 1

if you need the actual width the string occupies in pixels than use (see this MSDN link for more details):

Graphics.MeasureString(String, Font)

if you only need the "length" of the string i.e. no. of characters than use (see this MSDN link for more details):

str.Length

dont forget to bing / google :)

hope this helps!

Answer 2

There is no such thing as the "width" of a string variable or string value. You can get the length, i.e. the number of characters in the string, using the Length property:

            string str = "Hello word windows app store";
            int length = str.Length;

If you want to get the width of a TextBlock element that displays the string on the screen in your application you could use the ActualWidth property of the TextBlock element:

<TextBlock x:Name="byTBlock" Text="Hello word windows app store"/> 

double width = byTBlock.AcualWidth;

Hope that helps.

Graphics.MeasureString(String, Font) can not use in windows store app.

TextBlock has Measure() method, as following:

Size MeasureString(string content, Size availableSize, double fontSize, string fontFamily="Segoe UI")
{
    TextBlock tb = new TextBlock();

    tb.TextWrapping = TextWrapping.Wrap;
    tb.Text = content;
    tb.FontFamily = new Windows.UI.Xaml.Media.FontFamily(fontFamily);
    tb.FontSize = fontSize;
    tb.Measure(availableSize);

    return tb.DesiredSize;
}

Test:

string str = "Hello word windows app store";

Size size = MeasureString(str, new Size(800, 600), 40);

Size MeasureString(string content, Size availableSize, double fontSize, string fontFamily="Segoe UI")
{
    TextBlock tb = new TextBlock();

    tb.TextWrapping = TextWrapping.Wrap;
    tb.Text = content;
    tb.FontFamily = new Windows.UI.Xaml.Media.FontFamily(fontFamily);
    tb.FontSize = fontSize;
    tb.Measure(availableSize);

    Size actualSize = new Size();
    actualSize.Width = tb.ActualWidth;
    actualSize.Height = tb.ActualHeight;

    //return tb.DesiredSize;
    return actualSize;
}

actual size
