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

Returns a value indicating whether this instance is equal to a specified object.

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

Syntax

'Declaration
Public Overrides Function Equals ( _
    value As Object _
) As Boolean
public override bool Equals(
    Object value
)

Parameters

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

Return Value

Type: System.Boolean
true if value is a TimeSpan object that represents the same time interval as the current TimeSpan structure; otherwise, false.

Examples

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

' TimeSpan.Equals( Object ) methods.

Module Example
