Steps to Reproduce:
- Create new console project
- Add references to Roslyn 3.11.0
- Add to Program.cs:
using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using System;
namespace ConsoleApp3
{
class Program
{
static void Main(string[] args)
{
var tokens = SyntaxFactory.ParseTokens("\t\t/// <summary>\r\n\t\t/// Creates an immutable snapshot of this document.\r\n\t\t/// </summary>\r\n\t\tIDocument CreateDocumentSnapshot();\r\n");
var visitor = new TestWalker();
foreach (var token in tokens)
{
visitor.VisitToken(token);
}
}
}
class TestWalker : CSharpSyntaxWalker
{
public TestWalker()
: base(SyntaxWalkerDepth.StructuredTrivia)
{
}
public override void VisitToken(SyntaxToken token)
{
base.VisitToken(token);
var span = token.GetLocation().GetLineSpan();
Console.WriteLine(token.Kind() + " " + span);
}
}
}Expected Behavior:
Prints a list of tokens and their line spans.
Actual Behavior:
token.GetLocation().GetLineSpan() crashes with a
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. (Parameter 'position')
