Hi, I created a Demo.resx and I included it to my project, when I try to compile it showing.
Error :Invalid Resx file. Invalid character in the given encoding. Line 1, position 1. <File Path>\Demo.resx
Can any one explain why this error is occurring and how to rectify it?

Umm, resx files look NOTHING like that.
Are you sure you don't want a new class file?

This is an example of a resx file:

<?xml version="1.0" encoding="utf-8"?>
<root>

    that is mostly human readable. The generation and parsing of the

    associated with the data types.

Thank you plater.

          ResourceWriter rw = new ResourceWriter("Demo.resx");
          using (Image image = Image.FromFile("logo.gif"))
          {
             rw.AddResource("WroxLogo", image);
             rw.AddResource("Title", "Professional C#");
          }

Actually, I am encoding a .gif file and created a resx file through code then referred(Added) to my project.
I am unable to understand the concept of ‘Resource writer’, ‘Resource Reader’, and ‘Resource Manager’. Can any one give some simple example to understand the concept (and if you have time please give with explanation)?
Thank you.

I am getting this Exception..

"Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"Demo.resources\" was correctly embedded or linked into assembly \"NameSpace\" at compile time, or that all the satellite assemblies required are loadable and fully signed."

Till i am trying...

Changed the Code like

ResourceManager rm = new ResourceManager("Demo", Assembly.LoadFile(@"filePath/Demo.resources"));

Now, Here i am getting error

[CyberSoftHari]

My AssemblyVersion is

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

I am Creating Resource file

      ResourceWriter rw = new ResourceWriter("Demo.resources");  
          using (Image image = Image.FromFile("logo.gif"))
          {
             rw.AddResource("WroxLogo", image);
             rw.AddResource("Title", "Professional C#");
             rw.Close();
         }

I added the resource file to my project and in below code i am get back my image and title

ResourceManager rm = new ResourceManager("Demo", Assembly.GetExecutingAssembly());
            try
            {
                logo.Image = (Image)rm.GetObject("WroxLogo");
                textTitle.Text = rm.GetString("Title");
            }
           //Catch Block here
 

logo.Image = (Image)rm.GetObject("WroxLogo");

in this line My problem Starts and showing error

"Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"Demo.resources\" was correctly embedded or linked into assembly \"Namespace\" at compile time, or that all the satellite assemblies required are loadable and fully signed."


Can any one explain me why this Exception is throwing?

[CyberSoftHari]

I solved my problem.

I am using ResourceManager, which is wrong
I have to use ResourceSet
ResourceSet rs = new ResourceSet("Demo.resources");
