Byte.MaxValue Field

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Represents the largest possible value of a Byte. This field is constant.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Const MaxValue As Byte

public const byte MaxValue

Remarks

The value of this constant is 255 (hexadecimal 0xFF).

Examples

The following example demonstrates how to use the MaxValue field to screen variable inputs for values that are outside the range of possible byte values.

      Public Sub MinMaxFields(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal numberToSet As Integer)
         If numberToSet <= CInt([Byte].MaxValue) And numberToSet >= CInt([Byte].MinValue) Then
            ' You must explicitly convert an integer to a byte.
            MemberByte = CType(numberToSet, [Byte])

            ' Displays MemberByte using the ToString() method.
            outputBlock.Text += String.Format("The MemberByte value is {0}.", MemberByte.ToString()) & vbCrLf
         Else
            outputBlock.Text += String.Format("The value {0} is outside of the range of possible Byte values.", numberToSet.ToString()) & vbCrLf
         End If
      End Sub 'MinMaxFields

public void MinMaxFields(System.Windows.Controls.TextBlock outputBlock, int numberToSet)
{
   if (numberToSet <= (int)Byte.MaxValue && numberToSet >= (int)Byte.MinValue)
   {
      // You must explicitly convert an integer to a byte.
      MemberByte = (Byte)numberToSet;

      // Displays MemberByte using the ToString() method.
      outputBlock.Text += String.Format("The MemberByte value is {0}", MemberByte.ToString()) + "\n";
   }
   else
   {
      outputBlock.Text += String.Format("The value {0} is outside of the range of possible Byte values", numberToSet.ToString()) + "\n";
   }
}
