VB.Net Properties - Public Get, Private Set

问题:

I figured I would ask... but is there a way to have the Get part of a property available as public, but keep the set as private?

Otherwise I am thinking I need two properties or a property and a method, just figured this would be cleaner.

回答1:

Yes, quite straight forward:

Private _name As String

Public Property Name() As String
    Get
        Return _name
    End Get
    Private Set(ByVal value As String)
        _name = value
    End Set
End Property

I'm not sure what the minimum required version of Visual Studio is, but in VS2015 you can use

Public ReadOnly Property Name As String

It is read-only for public access but can be privately modified using _Name

回答3:

    Public Property Name() As String
        Get
            Return _name
        End Get
        Private Set(ByVal value As String)
            _name = value
        End Set
   End Property

One additional tweak worth mentioning: I'm not sure if this is a .NET 4.0 or Visual Studio 2010 feature, but if you're using both you don't need to declare the value parameter for the setter/mutator block of code:

Private _name As String

Public Property Name() As String
    Get
        Return _name
    End Get
    Private Set
        _name = value
    End Set
End Property

I find marking the property as readonly cleaner than the above answers. I believe vb14 is required.

Private _Name As String

Public ReadOnly Property Name() As String
    Get
        Return _Name
    End Get
End Property

This can be condensed to

Public ReadOnly Property Name As String

If you are using VS2010 or later it is even easier than that

Public Property Name as String

You get the private properties and Get/Set completely for free!
