The following example shows how to use the Result method to specify an expected return value. This code example is part of a larger example provided for the ContractClassAttribute class.

int IArray.Add(Object value)
{
    // Returns the index in which an item was inserted.
    Contract.Ensures(Contract.Result<int>() >= -1);
    Contract.Ensures(Contract.Result<int>() < ((IArray)this).Count);
    return default(int);
}

Function Add(ByVal value As Object) As Integer Implements IArray.Add
    ' Returns the index in which an item was inserted.
    Contract.Ensures(Contract.Result(Of Integer)() >= -1) '
    Contract.Ensures(Contract.Result(Of Integer)() < CType(Me, IArray).Count) '
    Return 0
    
End Function 'IArray.Add

Remarks

This method can be used only in the conditional expression for the Ensures contract.
