Get Started with Microsoft .NET
R2026bThe MATLAB interface to .NET lets you bring .NET assemblies into the MATLAB environment to construct objects from classes contained in the assemblies, and to call methods on these objects.
MATLAB supports loading these .NET assemblies:
.NET, including .NET Core (Microsoft® Windows®, macOS, and Linux®)
.NET Framework (Windows only)
For details, see System Requirements for Using MATLAB Interface to .NET. For information about .NET versions compatible with MATLAB, see MATLAB Interfaces to Other Languages.
To determine if your system has a supported version, use the NET.isNETSupported function.
Functions
NET.addAssembly | Make .NET assembly visible to MATLAB |
NET.unloadAssembly | Unload .NET Core assembly from MATLAB (Since R2026a) |
NET.isNETSupported | Check for supported version of Microsoft .NET |
NET.interfaceView | Explicit interface view of .NET object (Since R2023b) |
Classes
NET.Assembly | Members of .NET assembly |
Objects
NET.NetException | Capture error information for .NET exception |
Namespaces
NET | Summary of functions and classes in MATLAB .NET interface |
Topics
- System Requirements for Using MATLAB Interface to .NET
Using a supported version of .NET.
- Access Simple .NET Classes
These examples show how to access .NET functionality already installed on your system.
- Build and Load .NET Assembly for MATLAB
Build and load a .NET assembly.
- Save and Load .NET Objects in MAT Files
When you save and load .NET objects in MAT files, MATLAB uses
System.Runtime.Serialization.DataContractSerializerto perform the serialization and deserialization. - Simplify .NET Class Names
Use the MATLAB
importfunction to refer to .NET class names. - Use import in MATLAB Functions
Guidelines for using the
NET.addAssemblyandimportfunctions. - Use .NET Nested Classes and Enumerations
Using reflection to instantiate a nested class or enumeration.
- Handle .NET Exceptions
MATLAB catches exceptions thrown by .NET and converts them into a
NET.NetExceptionobject. - Assembly Is a Library of .NET Classes
An assembly is a collection of types and resources built to work together and form a logical unit of functionality in .NET applications.
- Use .NET from MATLAB
How you can benefit from using .NET from MATLAB.
- Create .NET Objects
How to create a .NET object.
- .NET Terminology
Understanding namespaces and reference and value types.
- Work with Microsoft Excel Spreadsheets Using .NET
This example for Microsoft .NET Framework uses the
Microsoft.Office.Interop.Excel.ApplicationClassclass to create a spreadsheet, copy MATLAB data to it, and then close it. - Work with Microsoft Word Documents Using .NET
This example for Microsoft .NET Framework uses the
Microsoft.Office.Interop.Word.ApplicationClassclass to create a Word document.
