What can we really do
with RAIL?
//Create the
RAssemblyDef instance for the Teste3.exe assembly
nRAssemblyDef rAssembly =
RAssemblyDef.LoadAssembly("Teste3.exe");
n//Get the RType object
of the FooBar type
RType rtd =
rAssembly.RModuleDef.GetType("FooBar");
n//Create an array of
RParameter objects
nRParameter [] paramsz = new
RParameter[1];
//Set the first
element of the array
nparamsz[0] = new
RParameter(0,rAssembly.GetType("System.String"));
n//Get the method which
code is to be inserted at the start of the method
RMethodDef rmd0 = (RMethodDef)rtd.GetMethod("WriteToScreenBefore",rAssembly.GetType("System.Void"),paramsz);
n//Get the method which
code is to be inserted at the end of the method
RMethodDef rmd1 = (RMethodDef)rtd.GetMethod("WriteToScreenAfter",rAssembly.GetType("System.Void"),paramsz);
n//Get the method to
instrument
nRMethodDef rmd2 =
(RMethodDef)rtd.GetMethod("MyMethod",rAssembly.GetType("System.Void"),paramsz);
//Create the
CodeTransformer object
nCodeTransformer cc = new
CodeTransformer();
n//Set the
transformations to make in the code
cc.InsertAtMethodStart(rmd0);
ncc.InsertAtMethodEnd(rmd1);
n//Apply the change to
the code
rmd2.Accept(cc);
n//Save the new
assembly
nrAssembly.SaveAssembly("Teste3.exe");
