StreamReader Resource file 'System.ArgumentNullException' System.ArgumentNullException: 'Value cannot be null. Parameter name: stream'

I am trying to read a file in my resource file (I have changed Build action to Embedded Resource). I get an Argument Null exception...not sure what I am missing?

Imports System.IO
Imports System.Reflection

Dim assembly As Assembly = Assembly.GetExecutingAssembly()
Dim reader As New StreamReader(Assembly.GetManifestResourceStream("File.sym")) ' Argument Null occurs System.ArgumentNullException: 'Value cannot be null. Parameter name: stream'

' Open the file and start reading each line
Do
    Dim mapping As New Mapping()
    line = reader.ReadLine
    If line Is Nothing Then Continue Do
    m = Regex.Match(line, "([^][]*)]")
    n = m.Groups(1).ToString()
    mapping.n = n
Solution

    I needed to add the below line;

    Dim resourceName = "TraceConverter.File.sym" 'Added line
Dim reader As New StreamReader(assembly.GetManifestResourceStream(resourceName))
