How to reference a library from execution assembly?

Question

I have an application referencing let's say : DLL 1 and DLL 2.

Within the application the end user can write some code for some customized functions.

Inside my application I compile their code using :

// User's code
string code = @" ** User's code ** ";

// Create the provider
CSharpCodeProvider provider = new CSharpCodeProvider();

// Create the parameters
CompilerParameters parameters = new CompilerParameters();

// Compile the user's code 
CompilerResults results = provider.CompileAssemblyFromSource(parameters, code);

Before the compilation, I would like to add some references that are already used withing my application which are DLL 1 and DLL 2 (in order to let the user use some of my functions).

I tried to use GetExecutingAssembly, but it returns the main application assembly and I can't find how to get DLL 1 and DLL 2.

Assembly.GetExecutingAssembly

I don't know the path of the DLL's so the following instruction won't work :

parameters.ReferencedAssemblies.Add("C:\DLL1.dll");

How can I solve that?

Answer 1

You can get the assembly location from a type defined within that assembly. So in your CompilerParameters you can reference them like this:

new CompilerParameters
{
    ReferencedAssemblies =
    {
        typeof(MyDll1.Type1).Assembly.Location,
        typeof(MyDll2.Type2).Assembly.Location
        //, etc
    }
    //, etc
}
