How to create a Hash Code from Source Code in C#?

Question

The problem:

I am trying to create a function that creates a hash code of the source code of my asp.net web application backend.

As long as nothing gets changed, this hash code needs to be identical. Even if I rebuild my project.

Does someone know, how I can do that?

What I tried:

The only working solution I found is to concat all important files to a big string and create a hash code out of it.

The problem of this solution is, that I have to add all the source files to the output directory, what shouldn't be done for security reasons.

Hope someone has a great idea =)

Thanks in advance!

Update:

I could solve my problem by enabling deterministic build as Renat suggested.

Just added the deterministic flag to my .csproj file as follows:

<Deterministic>True</Deterministic>

Answer 1

Even if I rebuild my project

You may use Deterministic Build , then it will produce the same binaries in each build being made out of same source codes. Then you may get the hash of binaries.
