A Windows managed method detouring library that supports both x86 and x64 detours.
- Download and install Juno using NuGet
The example below describes a basic implementation of the library
using Juno;
public class TestClass1
{
public void TestMethod1()
{
Console.WriteLine("Original method called");
}
}
public class TestClass2
{
public void TestMethod2()
{
Console.WriteLine("Detoured method called");
}
}
var detour = new MethodDetour<TestClass1, TestClass2>("TestMethod1", "TestMethod2");
var testClass = new TestClass1();
// Calls the original method as expected
testClass.TestMethod1();
// Add the method detour
detour.InitialiseDetour();
// Calls the target (detoured) method (TestClass2.TestMethod2)
testClass.TestMethod1();
// Remove the method detour
detour.RemoveDetour();
// Calls the original method
testClass.TestMethod1;In lieu of providing a set of classes and method names, you can provide a set of MethodInfo datatypes.
var detour = new MethodDetour(MethodInfo1, MethodInfo2);-
Both original and detoured classes must have the same layout of instance variables if you wish to access them.
-
Both original and detoured methods cannot be inlined be the compiler.
-
Detoured methods must match the method signature of the original method (same parameters & return type.)
