I have this class :
class LyricsItem
{
public LyricsItem()
{
}
public LyricsItem(LyricsItem item)
{
this.searchUrl = item.searchUrl;
this.croppingRegex = item.croppingRegex;
}
private string _searchUrl;
private string _croppingRegex;
public string searchUrl
{
get { return _searchUrl; }
set { _searchUrl = value; }
}
public string croppingRegex
{
get { return _croppingRegex; }
set { _croppingRegex = value; }
}
}
And this is Array with items LyricsItem
:
public List<LyricsItem> lyricsArray;
This is how i add items to the array :
LyricsItem item = new LyricsItem();
item.croppingRegex = croppingRegex;
item.searchUrl = searchurl;
lyricsArrayTmp.Add(item);
And i want to add it to IsolatedStorageSettings
:
IsolatedStorageSettings appSettings = IsolatedStorageSettings.ApplicationSettings;
if (appSettings.Contains("lyricsData"))
{
appSettings["lyricsData"] = lyricsArray;
}
else
{
appSettings.Add("lyricsData", lyricsArray);
}
appSettings.Save();
But When i get to save the IsolatedStorageSettings i get this exception:
The collection data contract type 'System.Collections.Generic.List`1[[**********, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' cannot be deserialized because it does not have a public parameterless constructor. Adding a public parameterless constructor will fix this error. Alternatively, you can make it internal, and use the InternalsVisibleToAttribute attribute on your assembly in order to enable serialization of internal members - see documentation for more details
You can't serialize a private class in the ApplicationSettings. Declare it as public instead:
public class LyricsItem
{
public LyricsItem()
{
}
public LyricsItem(LyricsItem item)
{
this.searchUrl = item.searchUrl;
this.croppingRegex = item.croppingRegex;
}
private string _searchUrl;
private string _croppingRegex;
public string searchUrl
{
get { return _searchUrl; }
set { _searchUrl = value; }
}
public string croppingRegex
{
get { return _croppingRegex; }
set { _croppingRegex = value; }
}
}
