how to serialize/deserialize an assembly object to and from a byte array

Question

Let\'s say a create an (executable) assembly in memory by compiling a code string. Then I want to serialize this assembly object into a byte array and then store it in a da

Answer 1

Here is my example:

public static byte[] SerializeAssembly()
{
  var compilerOptions = new Dictionary { { "CompilerVersion", "v4.0" } };
  CSharpCodeProvider provider = new CSharpCodeProvider(compilerOptions);

  CompilerParameters parameters = new CompilerParameters()
  {
    GenerateExecutable = false,
    GenerateInMemory = false,
    OutputAssembly = "Examples.dll",
    IncludeDebugInformation = false,
  };
  parameters.ReferencedAssemblies.Add("System.dll");

  ICodeCompiler compiler = provider.CreateCompiler();
  CompilerResults results = compiler.CompileAssemblyFromSource(parameters, StringClassFile());

  return File.ReadAllBytes(results.CompiledAssembly.Location);
}

private static Assembly DeserializeAssembyl(object fromDataReader)
{
  byte[] arr = (byte[])fromDataReader;
  return Assembly.Load(arr);
}



private string StringClassFile()
    {
      return "using System;" +
      "using System.IO;" +
      "using System.Threading;" +
      "namespace Examples" +
      "{" +
      " public class FileCreator" +
      " {" +
      "     private string FolderPath { get; set; }" +
      "     public FileCreator(string folderPath)" +
      "     {" +
      "         this.FolderPath = folderPath;" +
      "     }" +
      "     public void CreateFile(Guid name)" +
      "     {" +
      "         string fileName = string.Format(\"{0}.txt\", name.ToString());" +
      "         string path = Path.Combine(this.FolderPath, fileName);" +
      "         if (!File.Exists(path))" +
      "         {" +
      "             using (StreamWriter sw = File.CreateText(path))" +
      "             {" +
      "                 sw.WriteLine(\"file: {0}\", fileName);" +
      "                 sw.WriteLine(\"Created from thread id: {0}\", Thread.CurrentThread.ManagedThreadId);" +
      "             }" +
      "         }" +
      "         else" +
      "         {" +
      "             throw new Exception(string.Format(\"duplicated file found {0}\", fileName));" +
      "         }" +
      "     }" +
      " }" +
      "}";
    }
