Linq select to new object

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

Solution 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());

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();
