Decimal.Equals Method (Object)

Returns a value indicating whether this instance and a specified Object represent the same type and value.

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

public override bool Equals(
	Object value
)

Parameters

value
Type: System.Object
The object to compare with this instance.

Return Value

Type: System.Boolean
true if value is a Decimal and equal to this instance; otherwise, false.

The following code example compares several Decimal and other objects to a reference Decimal value using the Equals method.


// Example of the decimal.CompareTo and decimal.Equals instance 
// methods.
using System;

class DecCompToEqualsObjDemo

    // Get the exception type name; remove the namespace prefix.
    public static string GetExceptionType( Exception ex )
    {
        string exceptionType = ex.GetType( ).ToString( );
        return exceptionType.Substring( 
            exceptionType.LastIndexOf( '.' ) + 1 );
    }

    // Compare the decimal to the object parameters, 
    // and display the object parameters with the results.
    public static void CompDecimalToObject( decimal Left, 
        object Right, string RightText )
    {

        Console.WriteLine( "{0,-46}{1}", "object: "+RightText,

            Console.WriteLine( "{0}\n", Left.CompareTo( Right ) );
        }
        catch( Exception ex )
        {

            "decimal \nvalues and compares them with the following " +
            "reference value.\n" );

        // Create a reference decimal value.
        decimal Left = new decimal( 987.654 );

            "Left: decimal( 987.654 )", Left );

        // Create objects to compare with the reference.
        CompDecimalToObject( Left, new decimal( 9.8765400E+2 ), 
            "decimal( 9.8765400E+2 )" );

        CompDecimalToObject( Left, 987.6539M, "987.6539D" );
        CompDecimalToObject( Left, 
            new decimal( 987654000, 0, 0, false, 6 ), 
            "decimal( 987654000, 0, 0, false, 6 )" );
        CompDecimalToObject( Left, 9.8765400E+2,
