Question

I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic’s And and Or in C#?

For example, consider the following VB.NET code. The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic’s And operator is perfect for this situation, but unfortunately there’s no equivalent operator in C# as far as I know (&& short-circuits).

Return _
    Me.ValidateForControl(Me.firstNameTextBox) And
    Me.ValidateForControl(Me.middleNameTextBox) And
    Me.ValidateForControl(Me.lastNameTextBox) And
    Me.ValidateForControl(Me.streetAddressTextBox) And
    Me.ValidateForControl(Me.cityTextBox) And
    Me.ValidateForControl(Me.stateComboBox) And
    Me.ValidateForControl(Me.zipCodeMaskedTextBox) And
    Me.ValidateForControl(Me.phoneMaskedTextBox) And
    Me.ValidateForControl(Me.emailAddressTextBox) And
    Me.ValidateForControl(Me.checkInDateTimePicker) And
    Me.ValidateForControl(Me.checkOutDateTimePicker) And
    Me.ValidateForControl(Me.rentalUnitsGroupBox)

Also, for booleans, is ^ in C# equivalent to Xor in Visual Basic?
