I am messing around with the Roslyn scripting stuff (using the Microsoft.CodeAnalysis.CSharp.Scripting
nuget package), and I wonder if there is a way to add line nu
I got something working by emitting an (in-memory) assembly with debug information.
Example code:
var code = @"
var a = 0;
var b = 1 / a;
";
var script = CSharpScript.Create(code);
var compilation = script.GetCompilation();
var ilstream = new MemoryStream();
var pdbstream = new MemoryStream();
compilation.Emit(ilstream, pdbstream);
var assembly = Assembly.Load(ilstream.GetBuffer(), pdbstream.GetBuffer());
var type = assembly.GetType("Submission#0");
var factory = type.GetMethod("");
var submissionArray = new object[2];
Task
The output is (notice the :line 3
in the stack trace):
at Submission#0.<>d__0.MoveNext() in :line 3
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()
at UnitTests.ExploreRoslyn.d__13.MoveNext() in D:\dev\misc\netmockery\UnitTests\ExploreRoslyn.cs:line 151
Now obviously this is a bit of a hack, and I'm not really happy with the hardcoded script engine implementation details (Submission#0
,
), plus I don't really know what I'm doing. There should be (and maybe there is?) a better way.
