Decimal.Compare Method

Compares two specified Decimal values and returns an integer that indicates whether the first value is greater than, less than, or equal to the second value.

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

public static int Compare(
	decimal d1,
	decimal d2


Type: System.Decimal
A Decimal.
Type: System.Decimal
A Decimal.

Return Value

Type: System.Int32
A signed number indicating the relationship between d1 and d2.

Return Value


Less than zero

d1 is less than d2.


d1 and d2 are equal.

Greater than zero

d1 is greater than d2.

The following code example compares several Decimal values to a reference Decimal value using the Compare method.

// Example of the decimal.Compare and static decimal.Equals methods.
using System;

class Example
   const string dataFmt = "{0,-45}{1}";

   // Compare decimal parameters, and display them with the results.
   public static void CompareDecimals(System.Windows.Controls.TextBlock outputBlock, decimal Left, decimal Right,
       string RightText)
      outputBlock.Text += "\n";
      outputBlock.Text += String.Format(dataFmt, "Right: " + RightText, Right) + "\n";
      outputBlock.Text += String.Format(dataFmt, "decimal.Equals( Left, Right )",
          Decimal.Equals(Left, Right)) + "\n";
      outputBlock.Text += String.Format(dataFmt, "decimal.Compare( Left, Right )",
          Decimal.Compare(Left, Right)) + "\n";

          "decimal.Equals( decimal, decimal ) and \n" +
          "decimal.Compare( decimal, decimal ) methods " +

This example of the decimal.Equals( decimal, decimal ) and
decimal.Compare( decimal, decimal ) methods generates the
following output. It creates several different decimal
values and compares them with the following reference value.

Left: decimal( 123.456 )                     123.456

Right: decimal( 1.2345600E+2 )               123.456
decimal.Equals( Left, Right )                True
decimal.Compare( Left, Right )               0

Right: 123.4561M                             123.4561
decimal.Equals( Left, Right )                False
decimal.Compare( Left, Right )               -1

Right: 123.4559M                             123.4559
decimal.Equals( Left, Right )                False
decimal.Compare( Left, Right )               1

Right: 123.456000M                           123.456000
decimal.Equals( Left, Right )                True
decimal.Compare( Left, Right )               0

Right: decimal( 123456000, 0, 0, false, 6 )  123.456000
decimal.Equals( Left, Right )                True
decimal.Compare( Left, Right )               0
