OpCodes

[sulan-blob]

Hey,

while building a Tracer with Mono.Cecil, I would like to just call/(insert into the IL Code) a static Method "static void Log(params object[] p)",
how could I do this?

I've added those two:

var tracerReference = module.ImportReference(typeof(TraceUtil).GetMethod("Log"));
var arrayReference = module.ImportReference(typeof(System.Array).GetMethod("Empty").MakeGenericMethod(typeof(System.Object)));

and afterwards I do:

... (Some Code)
ilProcessor.InsertBefore(firstInstruction, Instruction.Create(OpCodes.Nop));

ilProcessor.InsertBefore(firstInstruction, Instruction.Create(OpCodes.Call, arrayReference));

ilProcessor.InsertBefore(firstInstruction, Instruction.Create(OpCodes.Call, tracerReference));
... (Some Code)

the instructions which will be produced are:

nop
call T[] System.Array::Empty<System.Object>()
call System.Void TraceLogMethods.TraceUtil::LogMethodCall(System.Object[])
... (More Instructions)

I've already checked what instructions normaly would be for this kind of scenario
'call T[] System.Array::Empty<System.Object>()' this one should be (or that's what I want to achieve) 'call !!0[] System.Array::Empty<System.Object>()'.

How could I do it?

T&R,
