How c

Answer 1

Here is solution that uses aggregation:

const string separator = ".";
const string source = "Class1.StructA.StructB.StructC.FieldA";

// Get the components.
string[] components = source.Split(new [] { separator }, StringSplitOptions.None);

List results = new List();
// Aggregate with saving temporary results.
string lastResult = components.Aggregate((total, next) =>
    {
        results.Add(total);
        return string.Join(separator, total, next);
    });
results.Add(lastResult);
