Consider this C# pseudo-code:

public static void Main()
{
  Console.WriteLine();
}

I want to browse the assembly and discover where is the line containing the function "header" (i.e. the name, in my case - "Main"). Currently, I can get the method instructions and from them get the line which generates the first IL instruction. In my case this is the "Console.WriteLine()" line. Can I get to the header?
I know that it can span multiple lines, in this case, I would like to get to the starting line, if possible.

My current code looks like:

var metadataToken = new MetadataToken(functionMetadataToken);
var asm = AssemblyDefinition.ReadAssembly(assemblyFilepath, new ReaderParameters { ReadSymbols = true });
                var sp = (from modules in asm.Modules
                          from types in modules.Types
                          from method in types.Methods
                          where method.MetadataToken == metadataToken
                          select method.Body.Instructions)
                        .First().First().SequencePoint;

var line = sp.StartLine;

How can I improve it?
