Byte.CompareTo Method (Object)

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

Compares this instance to a specified object and returns an indication of their relative values.

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

Syntax

'Declaration
Public Function CompareTo ( _
    value As Object _
) As Integer

public int CompareTo(
    Object value
)

Parameters

value
Type: System.Object
An object to compare, or nulla null reference (Nothing in Visual Basic).

Return Value

Type: System.Int32
A signed integer that indicates the relationship of this instance to value.

Return Value	Description
Less than zero	This instance is less than value.
Zero	This instance is equal to value.
Greater than zero	This instance is greater than value. -or- value is nulla null reference (Nothing in Visual Basic).

Less than zero

This instance is less than value.

Zero

This instance is equal to value.

Greater than zero

This instance is greater than value.

-or-

value is nulla null reference (Nothing in Visual Basic).

Implements

IComparable.CompareTo(Object)

Exceptions

Exception	Condition
ArgumentException	value is not a Byte.

Remarks

value must be nulla null reference (Nothing in Visual Basic) or an instance of Byte; otherwise, an exception is thrown.

Any instance of Byte, regardless of its value, is considered greater than nulla null reference (Nothing in Visual Basic).

This method is implemented to support the IComparable interface.

Examples

The following code example demonstrates the CompareTo method.

Public Sub Compare(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal myByte As [Byte])
   Dim myCompareResult As Integer

   myCompareResult = MemberByte.CompareTo(myByte)

   If myCompareResult > 0 Then
      outputBlock.Text += String.Format("{0} is less than the MemberByte value {1}", myByte.ToString(), MemberByte.ToString()) & vbCrLf
   Else
      If myCompareResult < 0 Then
         outputBlock.Text += String.Format("{0} is greater than the MemberByte value {1}", myByte.ToString(), MemberByte.ToString()) & vbCrLf
      Else
         outputBlock.Text += String.Format("{0} is equal to the MemberByte value {1}", myByte.ToString(), MemberByte.ToString()) & vbCrLf
      End If
   End If
End Sub 'Compare

public void Compare(System.Windows.Controls.TextBlock outputBlock, Byte myByte)
{
   int myCompareResult;

   myCompareResult = MemberByte.CompareTo(myByte);

   if (myCompareResult > 0)
   {
      outputBlock.Text += String.Format("{0} is less than the MemberByte value {1}", myByte.ToString(), MemberByte.ToString()) + "\n";
   }
   else if (myCompareResult < 0)
   {
      outputBlock.Text += String.Format("{0} is greater than the MemberByte value {1}", myByte.ToString(), MemberByte.ToString()) + "\n";
   }
   else
   {
      outputBlock.Text += String.Format("{0} is equal to the MemberByte value {1}", myByte.ToString(), MemberByte.ToString()) + "\n";
   }
}
