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

[SecuritySafeCriticalAttribute]
public static int Compare(
	decimal d1,
	decimal d2
)

Parameters

d1
Type: System.Decimal
A Decimal.
d2
Type: System.Decimal
A Decimal.

Return Value

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

Return Value

Meaning

Less than zero

d1 is less than d2.

Zero

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;

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

   // Compare decimal parameters, and display them with the results.

          Decimal.Compare(Left, Right)) + "\n";

/*
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
