List<int> types = new List<int>();foreach (var d in myTableList){    if (!types.Contains((int)d.item_type))        types.Add((int)d.item_type);}I have a table in db called myTable. There is a column in it called item_type. It is integer.I want to make a list which would have all item_type which are in myTableList, but there shouldn't be duplicates.I tried:types = myTableList.Distinct(x => x.item_type)but I want types to be list of integers, not items of type myTable.
Optimizing a distinction code
c#;linq;entity framework
Trytypes = myTableList    .Select(x => (int)x.item_type)    .Distinct();You may also want to add .ToList() at the end if you want to match original code
