Short answer: you won't get the original C/C++/C# source out of a compiled DLL unless the author gives it to you or you reverse‑engineer it. 's suggestion to use Dependency Walker is a good first step — it shows exports and dependencies but not source or high‑level logic.

Practical next steps:

  • First determine whether the DLL is a .NET assembly or a native (unmanaged) PE. Try opening it in a .NET decompiler (ILSpy/dnSpy/dotPeek) — if it loads, you can often recover readable C# source. If it doesn't, treat it as native. On Windows you can also run a few quick checks from a Developer Command Prompt:
    dumpbin /headers mtb.dll
    dumpbin /exports mtb.dll
    strings mtb.dll | more
    corflags mtb.dll
  • If managed: use a decompiler to inspect namespaces, types and method bodies. If native: use Dependency Walker / dumpbin to list exports, use strings to find useful text, and a disassembler/decompiler (Ghidra, IDA, etc.) to inspect machine code — expect pseudocode, not original variable names or comments.

Practical tips tied to the thread: the C# code shown is using P/Invoke, which typically means the DLL is unmanaged. Also check for a signature mismatch: if the calling code passes an argument by reference, the extern declaration must match (for example, use ref or out on that parameter) and the native prototype must match the pointer semantics. Also watch 32‑bit vs 64‑bit: build your process to match the DLL’s bitness.

Cautions: confirm you have legal right to reverse‑engineer (EULA/contract may forbid it). If the DLL controls hardware, ask the vendor for the SDK or headers — that’s usually faster and safer than reverse engineering.

still cant find the code................anyone please help me................

Are you trying to find the source code to the mtb.dll?

ys............i want to see the source code within the mtb.dll file!!

Unless you reverse engineer it, or obtain it from the authors, you aren't going to get the source code.
