How to append, add resource entry to resource .resx file in C#

Notice: You need to add at least Read/Write permisions for NETWORK_SERWICE to .resx file.

	// helper class
	public class ResEntry
	{
	public string Entry { get; set; }
	public string Message { get; set; }
	}
	/// <summary>
	/// Method adds entries from resourceList to specified language resource file
	/// </summary>
	/// <param name="resDir">Cathalog where resources are stored</param>
	/// <param name="resourceList"></param>
	/// <param name="lang">Language prefix fg en - english, pl - polish, etc</param>
	public void CreateNewsResourceEntry(string resDir, List<ResEntry> resourceList, string lang)
	{
	string resxFile = Path.Combine(resDir, "News_." + lang + ".resx");
	List<ResEntry> currResList = new List<ResEntry>();
	using (ResXResourceReader resxReader = new ResXResourceReader(resxFile))
	{
	resxReader.UseResXDataNodes = true;
	foreach (DictionaryEntry entry in resxReader)
	{
	var node = (ResXDataNode)entry.Value;
	//FileRef is null if it is not a file reference.
	if (node.FileRef == null)
	{
	var value = node.GetValue((ITypeResolutionService)null);
	currResList.Add(new ResEntry()
	{
	Entry = (string)node.Name,
	Message = (string)value,
	});
	}
	}
	}
	currResList.AddRange(resourceList);
	using (ResXResourceWriter resx = new ResXResourceWriter(resxFile))
	{
	foreach (var item in currResList)
	resx.AddMetadata(item.Entry, item.Message);
	resx.Generate();
	}
	}
	// usage example in ASP.NET
	string resDir = Path.Combine(HttpRuntime.AppDomainAppPath, "App_GlobalResources");
	List<ResEntry> list = new List<ResEntry>(); in ASP.NET
	list.Add(new ResEntry() { Entry = "Title_1", Message = "Title_1" });
	list.Add(new ResEntry() { Entry = "Message_1", Message = "Message_2" });
	Controller.CreateNewsResourceEntry(resDir, list, "en");
