group successive numbers into the mass

[irl]

There's an object. List<int> For example,

var src = new List<int> {0,1,3,5,6,7,9};

There are no duplicates on the original list, that is. {0,1,1,3,5} Not considered. List pre-conditioned

how to write a function that will return the list of objects to which successive numbers will be applied, i.e. the following result is required:

var result = new List<List<int>>
{
    new List<int> {0,1},
    new List<int> {3},
    new List<int> {5,6,7},
    new List<int> {9}
};

I'm just thinking about making it in the cycle. for But I think you can do it more. elegant using linq

The method may be used here. https://msdn.microsoft.com/ru-ru/library/bb549218(v=vs.110).aspx with an initial battery value.

src.Aggregate(new List<List<int>>(), (acc, cur) =>
{
    //проверяем что мы, либо зашли в первый раз, либо разница между элементами больше 1.
    if (acc.Count == 0 || cur - acc.Last().Last() > 1)
    {
        //добавляем новый список с текущим элементом
        acc.Add(new List<int> { cur });
    }
    else
    {
        //иначе добавляем в последний список
        acc.Last().Add(cur);
    }
//возвращаем аккумулятор                
return acc;

});
