If you do not use the exact spelling and case of the file name, the method call to access theManifestResourceStreamreturns??? ???? ??, and the system does not raise an exception.

???:: If you want to verify the resource names, you can use the Microsoft Intermediate Language Disassembler (ILDASM) to view the Manifest data, which lists the included resources.

Access Resources

To access the resources that you have embedded in the Manifest of your assembly, import theSystem.IO??System.Reflectionnamespaces, as follows:
   using System.IO;
   using System.Reflection;
				
TheSystem.IOnamespace provides the definition of a stream and theSystem.Reflection??? ????? ????????? ???? ????????????? ?? ???? ??????? ??? ???????? ???????? ?? ??????? ?? ??? ??????? ?????? ????? ???

?? ?? ????? ??????? declaration ??????? ??? ?????, ??????? ?? ?????? ??????? ??? ???? ??? ?? ??? ???:
   Assembly _assembly;
   Stream _imageStream;
   StreamReader _textStreamReader;
				
???:: ?? ???????? ??????????? ??? ?????? ???, ?? ??? ????? ??????? ?????? ?????? ??? ???-????? ?????

??????? ??? ????????? ?? ??? ?? ?? ??????? ?? ?????? ?? ???? ?? ??? ?? ??????? ?? ?? ?????? ??????? ???? ????? ??? ???? ?? ???, ?? ?????GetExecutingAssemblyfollows ?? ??? ???, ??????? ????:
   _assembly = Assembly.GetExecutingAssembly();
				
Reading the information from the resource to a stream is performed with a method call toGetManifestResourceStream. The parameter that is passed to this method is the name of the resource that is to be accessed. The two resources are then read to their corresponding streams as the??? ????event of the form is executed.
   _imageStream = _assembly.GetManifestResourceStream("MyNameSpace.MyImage.bmp");
   _textStreamReader = new StreamReader(_assembly.GetManifestResourceStream("MyNameSpace.MyTextFile.txt"));
				
The code in the??? ????event for the form resembles the following:
   try
   {
      _assembly = Assembly.GetExecutingAssembly();
      _imageStream = _assembly.GetManifestResourceStream("MyNamespace.MyImage.bmp");
      _textStreamReader = new StreamReader(_assembly.GetManifestResourceStream("MyNamespace.MyTextFile.txt"));
   }
   catch
   {
      MessageBox.Show("Error accessing resources!");
   }
