SvgIconGenerator

RSCG – SvgIconGenerator    

Generates strongly-typed C# classes from SVG icon files at compile time — access SVG icons as typed properties with no runtime file I/O.

How to use

1. Add SVG files as AdditionalFiles in .csproj:

“`xml

“`

3. Declare a partial static class with [GenerateIcons]:

“`charp

[GenerateIcons()]

internal static partial class MyIcons;

“`

3. Access icons as typed members (one per SVG file):

“`charp

Console.WriteLine(MyIcons.Circle.Name); // “Circle”

Console.WriteLine(MyIcons.Rect.InnerContent); // SVG inner XML

“`

You can use for Embedding SVG icons as compile-time constants with typed access — no file paths, no reflection, no runtime loading.

This is how you can use SvgIconGenerator .

The code that you start with is

<project sdk="Microsoft.NET.Sdk">

  <propertygroup>
    <outputtype>Exe</outputtype>
    <targetframework>net10.0</targetframework>
    <implicitusings>enable</implicitusings>
    <nullable>enable</nullable>
  </propertygroup>

  <itemgroup>
    <packagereference version="0.0.4" include="SvgIconGenerator">
    </packagereference>
  </itemgroup>
	<itemgroup>
		<additionalfiles include="Icons/*.svg">
	</additionalfiles>

	<propertygroup>
		<emitcompilergeneratedfiles>true</emitcompilergeneratedfiles>
		<compilergeneratedfilesoutputpath>$(BaseIntermediateOutputPath)\GX</compilergeneratedfilesoutputpath>
	</propertygroup>
</itemgroup>

The code that you will use is

using DemoSvg;

Console.WriteLine(MyIcons.Circle.Name);

Console.WriteLine(MyIcons.Rect.InnerContent);

using System;
using System.Collections.Generic;
using System.Text;
using SvgIconGenerator;
namespace DemoSvg;

[GenerateIcons()]
internal static partial class MyIcons;
