[Question] Migrating from .Net Framework - Compiling wholesome files

[X39]

Summary

Hello there, i am currently migrating from .net framework to .net core and am facing issues during this process.

Prior i used CSScriptLibrary.CSScript.LoadCode to load a file as a whole and get the assembly returned, receiving the method later using a "default" method name.

The benefit has been that i had more control about what the methods can access easily, thanks to additional using instructions, and could place the code into a certain namespace, easing the navigation further.

The issue i now face is that this approach presents me with a You cannot declare namespace in script code error message.

The relevant code in question is as follows:

.Net Framework code

assembly = CSScriptLibrary.CSScript.LoadCode(code, assemblyPath, DEBUG_BUILD);

.Net Core code

CSScriptLib.CSScript.Evaluator.DebugBuild = DEBUG_BUILD;
assembly = CSScriptLib.CSScript.Evaluator.CompileCode(code, new CSScriptLib.CompileInfo
{
    AssemblyFile = assemblyPath
});

The outer shell for code is the follows:

const string preText = @"using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace X39.Trader.Data
{
    public class CSScriptClass
    {
        public static bool CSScriptMethod(
            X39.Trader.Api.Client client,
            X39.Trader.Data.Job job)
        {
";
const string postText = @"
        }
    }
}";

// class Condition { ... public string Code { get; set; } ... }
Condition condition = ...;
var code = String.Concat(preText, condition.Code, postText);

Is it possible to get the same behavior?

Thanks for your time, X39

yes it is possible. Try to use CSScript.CodeDomEvaluator it allows using namespaces.

The problem with Roslyn compiler is that it takes the script code and treats it as a class declaration. Whereas CodeDom treats it as a C# file.

Solved it already by pretty much updated all script files. Was substantially less work then i expected at first, thanks to some basic regex magic i did.

Thanks anyways :)
