What is C# equivalent of <map> in C++? [duplicate]

Solution 1:

The equivalent would be class SortedDictionary<TKey, TValue> in the System.Collections.Generic namespace.

If you don't care about the order the class Dictionary<TKey, TValue> in the System.Collections.Generic namespace would probably be sufficient.

Solution 2:

std::map<Key, Value> → SortedDictionary<TKey, TValue>

std::unordered_map<Key, Value> → Dictionary<TKey, TValue>

Solution 3:

Take a look at the Dictionary class in System::Collections::Generic.

Dictionary<myComplex, int> myMap = new Dictionary<myComplex, int>();

Solution 4:

.NET Framework provides many collection classes too. You can use Dictionary in C#. Please find the below msdn link for details and samples http://msdn.microsoft.com/en-us/library/xfhwa508.aspx
