I have defined a class myComplex. I need to map it to integers. In C++ I would have created a map as
map<myComplex,int> first;
How to do such thing in C#?
回答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.
回答2:
std::map<Key, Value> → SortedDictionary<TKey, TValue>
std::unordered_map<Key, Value> → Dictionary<TKey, TValue>
回答3:
Take a look at the Dictionary class in System::Collections::Generic.
Dictionary<myComplex, int> myMap = new Dictionary<myComplex, int>();
回答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
