Tuple<T1, T2, T3, T4, T5, T6, T7, TRest>.Equals Method

Returns a value that indicates whether the current Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object is equal to a specified object.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public override bool Equals(
	Object obj
)

Parameters

obj
Type: System.Object

The object to compare with this instance.

Return Value

Type: System.Boolean
true if the current instance is equal to the specified object; otherwise, false.

The obj parameter is considered to be equal to the current instance if it meets all the following conditions:

  • It is a Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object.

  • It has the same total number of components that are of the same types as the current instance.

  • Its components (including its nested components) are equal to those of the current instance. Equality is determined by the default equality comparer for each component.

The following example defines five Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> objects that contain prime numbers. It then compares the first object with each of the remaining objects. As the output shows, only the first and the last Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> objects are equal, because they have an identical number of components with identical values.
