[CLOSED] An empty string in a property with ClientConfig attribute not serialized

[tdracz]

Hello,

Let's say I have a class as follows:

class BaseSettingTreeNode : TreeNode
{
    public BaseSettingTreeNode()
    {
    }

    [ClientConfig]
    public string Test {get; set;}
}

When I serialize a tree nodes the following way:

TreeNodeCollection nodes = new TreeNodeCollection( false );
 nodes.Add(new BaseSettingTreeNode()
 {
     Test = string.Empty
 });
var json =  nodes.ToJson();

the Test property is not serialized at all and the resulting JSON is just "[{}]", which results in 'undefined' in JavaScript. I believe it should be "[{test:""}]". When a null value or any other non-empty string value is assigned to the Test property, it is serialized properly as "[{test:null}]" or "[{test:"test"}]".

Hi,

You need to define default value atrribute for property (if property equals default value then property will not be serialized)


Empty string will not be serialized

DefaultValue("")

Null string will not be serialized

DefaultValue(null)
