I have the following Auto Property
[DefaultValue(true)]
public bool RetrieveAllInfo { get; set; }
when I try to use it inside the code i find the default false for is false I assume this is the default value to a bool variable, does anyone have a clue what is wrong!?
The DefaultValue attribute is only used to tell the Visual Studio Designers (for example when designing a form) what the default value of a property is. It doesn't set the actual default value of the attribute in code.
More info here: http://support.microsoft.com/kb/311339
[DefaultValue] is only used by (for example) serialization APIs (like XmlSerializer), and some UI elements (like PropertyGrid). It doesn't set the value itself; you must use a constructor for that:
public MyType()
{
RetrieveAllInfo = true;
}
or set the field manually, i.e. not using an automatically implemented-property:
private bool retrieveAllInfo = true;
[DefaultValue(true)]
public bool RetrieveAllInfo {
get {return retrieveAllInfo; }
set {retrieveAllInfo = value; }
}
Or, with more recent C# versions (C# 6 or above):
[DefaultValue(true)]
public bool RetrieveAllInfo { get; set; } = true;
