Specifies a function that will calculate the value to return from the method, retrieving the arguments for the invocation.

Namespace: Moq.Language
Assembly: Moq (in Moq.dll) Version: 4.0.10827.0 (4.0.0.0)

Syntax

C#
IReturnsResult<TMock> Returns<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12>( Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, TResult> valueFunction )

Parameters

valueFunction: Type: System..::..Func<(Of <(<'T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, TResult>)>)>
The function that will calculate the return value.

Type Parameters

T1: The type of the first argument of the invoked method.
T2: The type of the second argument of the invoked method.
T3: The type of the third argument of the invoked method.
T4: The type of the fourth argument of the invoked method.
T5: The type of the fifth argument of the invoked method.
T6: The type of the sixth argument of the invoked method.
T7: The type of the seventh argument of the invoked method.
T8: The type of the eighth argument of the invoked method.
T9: The type of the nineth argument of the invoked method.
T10: The type of the tenth argument of the invoked method.
T11: The type of the eleventh argument of the invoked method.
T12: The type of the twelfth argument of the invoked method.

Examples

The return value is calculated from the value of the actual method invocation arguments. Notice how the arguments are retrieved by simply declaring them as part of the lambda expression:
