Linq to XML customize distinct function
Definition comparer class,
class ItemComparer : IEqualityComparer<XElement>
{
public bool Equals(XElement x, XElement y)
{
return x.Attribute("Name").Value == x.Attribute("Name").Value;
}
public int GetHashCode(XElement obj)
{
return obj.Attribute("Name").Value.GetHashCode();
}
}
How to use this one to distinct:
public List<string> LoadDistrict(string region)
{
if (m_DataDoc == null)
return null;
List<string> list = new List<string>();
try
{
var query = from r in m_DataDoc.Elements("DashBoardData").Elements("LevelData").Elements("Region").Where(a => a.Attribute("Name").Value.ToLower() == region.ToLower())
select r;
foreach (var district in query.Elements("District").Distinct(new ItemComparer()))
{
list.Add(district.Attribute("Name").Value);
}
return list;
}
catch (Exception exp)
{
MessageBox.Show(exp.Message);
return null;
}
}
