Byte.MaxValue Field
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Represents the largest possible value of a Byte. This field is constant.
public: System::Byte MaxValue = 255;
public const byte MaxValue = 255;
val mutable MaxValue : byte
Public Const MaxValue As Byte = 255
Value = 255
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:
void MinMaxFields( Int32 numberToSet )
{
if ( numberToSet <= (Int32)Byte::MaxValue && numberToSet >= (Int32)Byte::MinValue )
{
// You must explicitly convert an integer to a byte.
MemberByte = (Byte)numberToSet;
// Displays MemberByte using the ToString() method.
Console::WriteLine( "The MemberByte value is {0}", MemberByte.ToString() );
}
else
{
Console::WriteLine( "The value {0} is outside of the range of possible Byte values", numberToSet.ToString() );
}
}
public void MinMaxFields(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.
Console.WriteLine("The MemberByte value is {0}", MemberByte.ToString());
}
else
{
Console.WriteLine("The value {0} is outside of the range of possible Byte values", numberToSet.ToString());
}
}
let minMaxFields numberToSet =
if numberToSet <= int Byte.MaxValue && numberToSet >= int Byte.MinValue then
// You must explicitly convert an integer to a byte.
let myByte = byte numberToSet
printfn $"The MemberByte value is {myByte}"
else
printfn $"The value {numberToSet} is outside of the range of possible Byte values"
Public Sub MinMaxFields(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.
Console.WriteLine("The MemberByte value is {0}.", MemberByte.ToString())
Else
Console.WriteLine("The value {0} is outside of the range of possible Byte values.", numberToSet.ToString())
End If
End Sub
The value of this constant is 255 (hexadecimal 0xFF).
