How would i create a brtrue instruction with this operand.

[Hi_ImKyle]

Ok so I've been using Mono.Cecil for a bit now and all is good till i needed to create the brtrue instruction.

So this is what i have setup so far.

Instruction.Create(OpCodes.Ldsfld, ILUtils.GetField(Assembly.MainModule, "****.****", "****")), 

Instruction.Create(OpCodes.Call, Assembly.MainModule.ImportReference(typeof(MainTest).GetMethod("Chat_Hook"))), 

Instruction.Create(OpCodes.Brtrue, "")

This is what I'm trying to recreate

But whenever i try to create a brtrue instruction I always get an exception with the error message "opcode" which isnt useful at all.

Is there a way to have that operand in IL_01AD in Instruction.Create?

Assuming Instruction  is a ILProcessor, you need to pass the instruction you want to jump to Create(OpCodes.Brtrue)  (instead of a string)

something like this:

var target = Instruction.Create(OpCodes.Nop); // you can use any instruction.. to simplify I am adding a nop as the target

// add other instructions

Instuction.Emit(OpCodes.Brtrue, target);

// some more instructions

Instruction.Append(target);

// More instructions
