I am generating code assemblies at runtime using the following code:

CSharpCodeProvider cscp = new CSharpCodeProvider();
                  ICodeGenerator icg = cscp.CreateGenerator();
                  StringBuilder srcStringBuilder = new StringBuilder();
                  StringWriter sw = new StringWriter(srcStringBuilder);
                  icg.GenerateCodeFromNamespace(cns, sw, null);
                  proxySource = srcStringBuilder.ToString();
                  sw.Close();

// assembly compilation
                  CompilerParameters cp = new CompilerParameters();
                  cp.ReferencedAssemblies.Add("System.dll");
                  cp.ReferencedAssemblies.Add("System.Xml.dll");
                  cp.ReferencedAssemblies.Add("System.Web.Services.dll");
                  cp.ReferencedAssemblies.Add("System.Data.dll");
                  cp.ReferencedAssemblies.Add(System.Reflection.Assembly.
                        GetExecutingAssembly().Location);
      
                  cp.GenerateExecutable = false;
                  cp.GenerateInMemory = false;
                  cp.IncludeDebugInformation = false;

                  ICodeCompiler icc = cscp.CreateCompiler();
                  CompilerResults cr = icc.CompileAssemblyFromSource(cp, proxySource);

I have a hashtable that I would like to include into this assembly so that I can retrieve the hashtable later when I reload the assembly, using reflection.

What's the best way to include this hashtable into the assembly?

The requirements for this are actually quite simple. Just need to embed the key value pairs somewhere in the assembly so that later I can extract it using reflection. Any technique to do tthat will suffice.

Ok. I've pored over the c# compiler documentation and there is a param called Win32Resource of the compiler options object. If I set that param to the string name of a resource file, I can read that and add that serialized hashtable to the manifest resource stream of the assembly. I don't want to have to do that because that would incur more disk I/O than necessary. I wish there was a way to add the resource to the assembly without having to write it to the disk first... but that Win32Resource property takes a string filename, not a memory stream. Unless it can be tricked somehow??

Well, that's the idea anyway. =]. I will see if that works tomorrow, if that doesn't work, then I will be forced to serialze the hashtable to a filestream and then persist that on disk as a separate file!

All of this just to get the webservice description and method descripts from the WSDL file, after it is compiled into the proxy using wsdl.exe. (runtime version of that compiler anyway).

Does anyone know a better way?
