Hi,
I need to read file content and check something for update my application
modules and save something to file again , i wrote sample code :
AssemblyDefinition asm = AssemblyDefinition.ReadAssembly(@
"D:\1.exe");
var method = asm.MainModule.EntryPoint;
var mbi = method.Body.Instructions;
if (mbi[mbi.Count - 1].OpCode == OpCodes.Ret)
mbi.Remove(mbi[mbi.Count - 1]);
// Read text file buffer
mbi.Add(Instruction.Create(OpCodes.Ldstr, @"D:\\1.txt"));
mbi.Add(Instruction.Create(OpCodes.Call, asm.MainModule.Import(
typeof(File).GetMethod("ReadAllBytes", new Type[] { typeof(string) }))));
// Write the buffer to file
mbi.Add(Instruction.Create(OpCodes.Stloc_0));
mbi.Add(Instruction.Create(OpCodes.Ldstr, @"D:\2.txt"));
mbi.Add(Instruction.Create(OpCodes.Ldloc_0));
mbi.Add(Instruction.Create(OpCodes.Call, asm.MainModule.Import(
typeof(File).GetMethod("WriteAllBytes", new Type[] { typeof(string), typeof(
byte[]) }))));
asm.Write(@"D:\2.exe");
the problem is when i want to write the readed bytes to file again lose the
readed byte array and using Stloc_0 & Ldloc_0 kill my app .
my question is how can i access the readed bytes when my "WriteAllBytes"
method have 2 params and my stack gose to break ?
Thanks.
