Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a string to measure.

  • Creates a font object and sets it to Arial (16 point).

  • Creates a size object and uses it and the font object to measure the size of the string.

  • Draws a red rectangle using the measured size of the string.

  • Draws the string within the drawn rectangle.

public:
   void MeasureStringMin( PaintEventArgs^ e )
   {
      // Set up string.
      String^ measureString = "Measure String";
      System::Drawing::Font^ stringFont = gcnew System::Drawing::Font( "Arial",16 );

      // Measure string.
      SizeF stringSize = e->Graphics->MeasureString( measureString, stringFont );

      // Draw rectangle representing size of string.
      e->Graphics->DrawRectangle( gcnew Pen( Color::Red,1.0f ), 0.0F, 0.0F, stringSize.Width, stringSize.Height );

      // Draw string to screen.
      e->Graphics->DrawString( measureString, stringFont, Brushes::Black, PointF(0,0) );
   }
private void MeasureStringMin(PaintEventArgs e)
{

    // Set up string.
    string measureString = "Measure String";
    Font stringFont = new Font("Arial", 16);

    // Measure string.
    SizeF stringSize = new SizeF();
    stringSize = e.Graphics.MeasureString(measureString, stringFont);

    // Draw rectangle representing size of string.
    e.Graphics.DrawRectangle(new Pen(Color.Red, 1), 0.0F, 0.0F, stringSize.Width, stringSize.Height);

    // Draw string to screen.
    e.Graphics.DrawString(measureString, stringFont, Brushes.Black, new PointF(0, 0));
}
Private Sub MeasureStringMin(ByVal e As PaintEventArgs)

    ' Set up string.
    Dim measureString As String = "Measure String"
    Dim stringFont As New Font("Arial", 16)

    ' Measure string.
    Dim stringSize As New SizeF
    stringSize = e.Graphics.MeasureString(measureString, stringFont)

    ' Draw rectangle representing size of string.
    e.Graphics.DrawRectangle(New Pen(Color.Red, 1), 0.0F, 0.0F, _
    stringSize.Width, stringSize.Height)

    ' Draw string to screen.
    e.Graphics.DrawString(measureString, stringFont, Brushes.Black, _
    New PointF(0, 0))
End Sub

Remarks

The MeasureString method is designed for use with individual strings and includes a small amount of extra space before and after the string to allow for overhanging glyphs. Also, the DrawString method adjusts glyph points to optimize display quality and might display a string narrower than reported by MeasureString. To obtain metrics suitable for adjacent strings in layout (for example, when implementing formatted text), use the MeasureCharacterRanges method or one of the MeasureString methods that takes a StringFormat, and pass GenericTypographic. Also, ensure the TextRenderingHint for the Graphics is AntiAlias.

    e.Graphics.DrawString(measureString, stringFont, Brushes.Black, _
    New PointF(0, 0))
End Sub

Remarks

The width parameter specifies the maximum value of the width component of the returned SizeF structure (Width). If the width parameter is less than the actual width of the string, the returned Width component is truncated to a value representing the maximum number of characters that will fit within the specified width. To accommodate the entire string, the returned Height component is adjusted to a value that allows displaying the string with character wrap.

The MeasureString method is designed for use with individual strings and includes a small amount of extra space before and after the string to allow for overhanging glyphs. Also, the DrawString method adjusts glyph points to optimize display quality and might display a string narrower than reported by MeasureString. To obtain metrics suitable for adjacent strings in layout (for example, when implementing formatted text), use the MeasureCharacterRanges method or one of the MeasureString methods that takes a StringFormat, and pass GenericTypographic. Also, ensure the TextRenderingHint for the Graphics is AntiAlias.

Remarks

The MeasureString method is designed for use with individual strings and includes a small amount of extra space before and after the string to allow for overhanging glyphs. Also, the DrawString method adjusts glyph points to optimize display quality and might display a string narrower than reported by MeasureString. To obtain metrics suitable for adjacent strings in layout (for example, when implementing formatted text), use the MeasureCharacterRanges method or one of the MeasureString methods that takes a StringFormat, and pass GenericTypographic. Also, ensure the TextRenderingHint for the Graphics is AntiAlias.

MeasureString(String, Font, SizeF, StringFormat, Int32, Int32) MeasureString(String, Font, SizeF, StringFormat, Int32, Int32) MeasureString(String, Font, SizeF, StringFormat, Int32, Int32)

Measures the specified string when drawn with the specified Font and formatted with the specified StringFormat.

public:
 System::Drawing::SizeF MeasureString(System::String ^ text, System::Drawing::Font ^ font, System::Drawing::SizeF layoutArea, System::Drawing::StringFormat ^ stringFormat, [Runtime::InteropServices::Out] int % charactersFitted, [Runtime::InteropServices::Out] int % linesFilled);
public System.Drawing.SizeF MeasureString (string text, System.Drawing.Font font, System.Drawing.SizeF layoutArea, System.Drawing.StringFormat stringFormat, out int charactersFitted, out int linesFilled);
member this.MeasureString : string * System.Drawing.Font * System.Drawing.SizeF * System.Drawing.StringFormat *  *  -> System.Drawing.SizeF

Parameters

text
String String String

String to measure.

font
Font Font Font

Font that defines the text format of the string.

layoutArea
SizeF SizeF SizeF

SizeF structure that specifies the maximum layout area for the text.

stringFormat
StringFormat StringFormat StringFormat

StringFormat that represents formatting information, such as line spacing, for the string.

charactersFitted
Int32 Int32 Int32

Number of characters in the string.

linesFilled
Int32 Int32 Int32

Number of text lines in the string.

Returns

This method returns a SizeF structure that represents the size of the string, in the units specified by the PageUnit property, of the text parameter as drawn with the font parameter and the stringFormat parameter.

Exceptions

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a string to measure and a font object set to Arial (16 point)

  • Sets the maximum layout size of the string.

  • Creates a string format object and sets its format flags to DirectionVertical.

  • Creates the integer variables charactersFitted and linesFilled and a size object to measure the string.

  • Measures the size of the string and determines the number of characters fitted and lines filled, using the string, the font object, the maximum layout size, and the string format.

  • Draws a red rectangle using the measured size of the string.

  • Draws the string within the drawn rectangle.

  • Draws the values of the number of characters fitted and lines filled.

The result is a vertical rectangle enclosing a vertical string.
