NET.createDictionary

Generic .NET Dictionary

Since R2023a

Syntax

netDict = NET.createDictionary(mlDict)

Description

netDict = NET.createDictionary(mlDict) creates a generic .NET dictionary from a MATLAB^® dictionary.

Examples

Convert MATLAB Dictionary to .NET Dictionary

Create a MATLAB dictionary with two numeric entries. Convert the dictionary to use in .NET functions.

mlDict = dictionary("entry 1",3.14,"entry 2",42);
netDict = NET.createDictionary(mlDict)

netDict = 

  Dictionary<System*String,System*Double> with properties:

    Comparer: [1×1 System.Collections.Generic.GenericEqualityComparer<System*String>]
       Count: 2
        Keys: [1×1 System.Collections.Generic.Dictionary*KeyCollection<System*String,System*Double>]
      Values: [1×1 System.Collections.Generic.Dictionary*ValueCollection<System*String,System*Double>]

Input Arguments

mlDict — Configured MATLAB dictionary

dictionary

Configured MATLAB dictionary, specified as a dictionary.

Example: "entry 1",3.14,"entry 2",42

Output Arguments

netDict — .NET dictionary

System.Collections.Generic.Dictionary

.NET dictionary, returned as an instance of System.Collections.Generic.Dictionary<TKey, TValue> with equivalent entries as mlDict. The generic parameters are the .NET types that most closely match the types of keys and values in the MATLAB dictionary. For information about type conversions, see Pass Data to .NET Objects.

Version History

Introduced in R2023a

R2023a_plus: MATLAB dictionary with cell types map to .NET System.Object instead of System.Object[]

A MATLAB dictionary with entries of type cell are converted to a .NET dictionary with entries of type System.Object. Previously, the conversion was to System.Object[]. For more information, see Pass MATLAB Dictionary Data and How MATLAB Handles .NET Dictionary Objects.
