I want to use LINQ to convert this
IEnumerable<int>[] value1ByType = new IEnumerable<int>[3];
value1ByType[0]= new [] { 0};
value1ByType[1]= new [] {10,11};
value1ByType[2]= new [] {20};
var value2ToType = new Dictionary<int,int> {
{100,0},
{101,1},
{102,2},
{103,1}};
to this
var value2ToValue1 = new Dictionary<int,int> {
{100, 0},
{101,10},
{102,20},
{103,11}};
Is there a way to do this with LINQ? Without LINQ I would use multiple IEnumerators, one for each IEnumerable of value1ByType. like this:
// create enumerators
var value1TypeEnumerators = new List<IEnumerator<int>>();
for (int i = 0; i < value1ByType.Length; i++)
{
value1TypeEnumerators.Add(value1ByType[i].GetEnumerator());
value1TypeEnumerators[i].MoveNext();
}
// create wanted dictionary
var value2ToValue1 = new Dictionary<int, int>();
foreach (var item in Value2ToType)
{
int value1=value1TypeEnumerators[item.Value].Current;
value2ToValue1.Add(item.Key, value1);
value1TypeEnumerators[item.Value].MoveNext();
}
Any Idea how to do this in LINQ?
