Jvm.NET.Asm
A C# port of the ASM bytecode manipulation framework. Parses, modifies and generates Java class files — no JVM required.
Install
<PackageReference Include="Jvm.NET.Asm" Version="1.0.2" />
Usage
Read a class file
using Jvm.NET.Asm;
var bytes = File.ReadAllBytes("Foo.class");
var reader = new ClassReader(bytes);
Console.WriteLine($"class: {reader.GetClassName()}");
Console.WriteLine($"super: {reader.GetSuperName()}");
Modify and write back
using Jvm.NET.Asm;
var reader = new ClassReader(File.ReadAllBytes("Foo.class"));
var writer = new ClassWriter(ClassWriter.COMPUTE_MAXS);
reader.Accept(new ClassVisitor(writer)
{
// Override VisitMethod to intercept each method
public override MethodVisitor? VisitMethod(int access, string name, string descriptor,
string? signature, string[]? exceptions)
{
var mv = base.VisitMethod(access, name, descriptor, signature, exceptions);
if (name == "compute" && mv is not null)
return new MyMethodTransformer(mv);
return mv;
}
}, 0);
File.WriteAllBytes("Foo.class", writer.ToByteArray());
Generate a class from scratch
using Jvm.NET.Asm;
var writer = new ClassWriter(ClassWriter.COMPUTE_FRAMES);
writer.Visit(Opcodes.V1_8, Opcodes.ACC_PUBLIC, "HelloGen", null, "java/lang/Object", null);
var mv = writer.VisitMethod(Opcodes.ACC_PUBLIC | Opcodes.ACC_STATIC,
"main", "([Ljava/lang/String;)V", null, null);
mv.VisitFieldInsn(Opcodes.GETSTATIC, "java/lang/System", "out", "Ljava/io/PrintStream;");
mv.VisitLdcInsn("Hello from generated class!");
mv.VisitMethodInsn(Opcodes.INVOKEVIRTUAL, "java/io/PrintStream", "println", "(Ljava/lang/String;)V");
mv.VisitInsn(Opcodes.RETURN);
mv.VisitMaxs(2, 1);
mv.VisitEnd();
writer.VisitEnd();
File.WriteAllBytes("HelloGen.class", writer.ToByteArray());
