Linq select to new object

Question

I have a linq query

var x = (from t in types select t).GroupBy(g =>g.Type) 

which groups objects by their type, as a result I want to have single new object containing all of the grouped objects and their count. Something like this:

type1, 30     type2, 43     type3, 72 

to be more clear: grouping results should be in one object not an object per item type

Answer 1

Read : 101 LINQ Samples in that LINQ - Grouping Operators from Microsoft MSDN site

var x = from t in types  group t by t.Type          into grp              select new { type = grp.key, count = grp.Count() }; 

forsingle object make use of stringbuilder and append it that will do or convert this in form of dictionary

    // fordictionary    var x = (from t in types  group t by t.Type      into grp          select new { type = grp.key, count = grp.Count() })    .ToDictionary( t => t.type, t => t.count);      //for stringbuilder not sure for this    var x = from t in types  group t by t.Type          into grp              select new { type = grp.key, count = grp.Count() };   StringBuilder MyStringBuilder = new StringBuilder();    foreach (var res in x)   {        //: is separator between to object        MyStringBuilder.Append(result.Type +" , "+ result.Count + " : ");   }   Console.WriteLine(MyStringBuilder.ToString());    

Answer 2

The answers here got me close, but in 2016, I was able to write the following LINQ:

List<ObjectType> objectList = similarTypeList.Select(o =>     new ObjectType     {         PropertyOne = o.PropertyOne,         PropertyTwo = o.PropertyTwo,         PropertyThree = o.PropertyThree     }).ToList();
