I need to set a default value for a property, but I can't do it like this:
private int prop = 1;
public Prop
{
get { return prop;} ...
}
Because I need to serialize this class, and if I do it, I loose the default value.
Are you aware of any solution that works after the serialization and before, a开发者_如何学Cdding an attribute to the property?
I'm working with c# with framework 3.5.
DefaultValueAttribute
[DefaultValue("SomeValue")]
public string Prop { get; set; }
You can read a lot about serialization here: http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer.aspx
There is also:
''' <summary>
''' The defaults size for the list item.
''' </summary>
''' <value>Size.</value>
''' <returns>Size.</returns>
''' <remarks></remarks>
<Category("Appearance")> _
<Description("The defaults size for the list item.")> _
Public Property DefaultItemSize() As Size Implements IVisualList.DefaultItemSize
Get
Return m_DefaultItemSize
End Get
Set(ByVal value As Size)
m_DefaultItemSize = value
End Set
End Property
Protected Overridable Function ShouldSerializeDefaultItemSize() As Boolean
If m_DefaultItemSize.Equals(New Size(100, m_CellHeight)) Then Return False
Return True
End Function
or
Another option may be to use these attributes:
