17 Αυγ 2020 · If you want to use NumPy like functioninality in your cross platform C# Data Science project, my NumSharp Cheat Sheet can get you started.
I just recently noticed Dictionary.TryGetValue(TKey key, out TValue value) and was curious as to which is the better approach to retrieving a value from the Dictionary. I've traditionally done: if (myDict.Contains(someKey)) someVal = myDict[someKey]; ...
In NumPy a function like np.sqrt(a) can either return a scalar or an array, depending on the value passed into it. In C# we are trying to solve this by creating overloads for every scalar type in addition to the original function that takes an array and returns an array.
NumSharp is the C# version of NumPy, which is as consistent as possible with the NumPy programming interface, including function names and parameter locations. By introducing the NumSharp tool library, you can easily convert from python code to C# or F# code.

25 Ιουν 2019 · I have an API that returns a dictionary of dictionaries. I currently have this code to access the value of the dictionary, but it looks like a code smell. Is there a better way to structure this?
1 Μαΐ 2016 · Dictionary's have \$O(1)\$ key lookup and so if you change your inner loop to, SecondDictionary.TryGetValue. It'll achieve the same results without going through every item in SecondDictionary . Share
