Thanx Jb.
I was able to get and print one argument value of a method.
but error occured while executing console.exe which print two
arguments values. It looks fine when I see injected code with a
Reflector.
Can you give me a tips about code below, please?
private static void InjectCode(MethodDefinition p_method,
ModuleDefinition p_mainModule, string p_output)
{
ILProcessor il = p_method.Body.GetILProcessor();
MethodReference writeLineRef =
p_mainModule.Import(typeof(Console).GetMethod("WriteLine", new Type[]
{ typeof(string) }));
Instruction value1 = il.Create(OpCodes.Ldarg_1);
Instruction value2 = il.Create(OpCodes.Ldarg_2);
Instruction writeMessage = il.Create(OpCodes.Call,
writeLineRef);
Instruction writeMessage2 = il.Create(OpCodes.Call,
writeLineRef);
//var iList = new[] { value1, value2 };
il.InsertBefore(p_method.Body.Instructions[0], value1);
il.InsertAfter(value1, writeMessage);
il.InsertAfter(writeMessage, value2);
il.InsertAfter(value2, writeMessage2);
}
