Get Started with Microsoft .NET

Examples and concepts to help you quickly get started using .NET in MATLAB^®

The interface to .NET allows you to 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

Save and Load .NET Objects in MAT Files
When you save and load .NET objects in MAT files, MATLAB uses System.Runtime.Serialization.DataContractSerializer to perform the serialization and deserialization.

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.NetException object.
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.

Work with Microsoft Excel Spreadsheets Using .NET
This example for Microsoft .NET Framework uses the Microsoft.Office.Interop.Excel.ApplicationClass class 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.ApplicationClass class to create a Word document.
