This question is similar to http://stackoverflow.com/questions/2835192/linq-group-one-type-of-item but handled in a more generic way.
I have a List that has various derived classes. I may have something like this:
List<BaseClass> list = new List<BaseClass>() {
new Class1(1),
new Class2(1),
new Class1(2),
new Class3(1),
new Class2(2),
new Class4(1),
new Class3(2)
};
I am trying to use LINQ to semi-sort the list so that the natural order is maintained EXCEPT for certain classes which have base.GroupThisType == true. All classes with GroupThisType should be grouped together at the place that the first class of the same type occurs. Here is what the output should be like:
List<BaseClass> list = new List<BaseClass>() {
new Class1(1),
new Class1(2),
new Class2(1),
new Class3(1),
new Class3(2)
new Class2(2),
new Class4(1),
};
