trying to compile and execute C# code programmatically

The following is my code : ``` using System; using System.Collections.Generic; using System.Text; using System.CodeDom.Compiler; using System.IO; using Microsoft.CSharp; using System.Reflection; namespace DynaCode { class Program { static void Main(string[] args) { string content = File.ReadAllText(@"D:\hi.cs"); string[] code = new string[content.Length]; char[] seperators = { '\n','\r','\t' }; code = content.Split(seperators); CompileAndRun(code); Console.ReadKey(); } static void CompileAndRun(string[] code) { CompilerParameters CompilerParams = new CompilerParameters(); string outputDirectory = Directory.GetCurrentDirectory(); CompilerParams.GenerateInMemory = true; CompilerParams.TreatWarningsAsErrors = false; CompilerParams.GenerateExecutable = false; CompilerParams.CompilerOptions = "/optimize"; string[] references = { "System.dll"}; CompilerParams.ReferencedAssemblies.AddRange(references); CSharpCodeProvider provider = new CSharpCodeProvider(); CompilerResults compile = provider.CompileAssemblyFromSource(CompilerParams, code); if (compile.Errors.HasErrors) { string text = "Compile error: "; foreach (CompilerError ce in compile.Errors) { text += "rn" + ce.ToString(); } throw new Exception(text); } //ExpoloreAssembly(compile.CompiledAssembly); Module module = compile.CompiledAssembly.GetModules()[0]; Type mt = null; MethodInfo methInfo = null; if (module != null) { mt = module.GetType("DynaCore.DynaCore"); } if (mt != null) { methInfo = mt.GetMethod("Main"); } if (methInfo != null) { Console.WriteLine(methInfo.Invoke(null, new object[] { "here in dyna code" })); } } static void ExpoloreAssembly(Assembly assembly) { Console.WriteLine("Modules in the assembly:"); foreach (Module m in assembly.GetModules()) { Console.WriteLine("{0}", m); foreach (Type t in m.GetTypes()) { Console.WriteLine("t{0}", t.Name); foreach (MethodInfo mi in t.GetMethods()) { Console.WriteLine("tt{0}", mi.Name); } } } } } } ``` The contents of the hi.cs file is as follows: ``` using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace DynaCore { class DynaCore { static public void Main(string[] args) { Console.WriteLine("hello, this is good"); } } } ``` This is the error I get when I try to run this program: ``` System.Exception was unhandled Message="Compile error: rnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.16.cs(1,19) : error CS1514: { expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.16.cs(1,19) : error CS1513: } expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.18.cs(1,1) : error CS0116: A namespace does not directly contain members such as fields or methodsrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.20.cs(1,19) : error CS1514: { expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.20.cs(1,19) : error CS1513: } expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.20.cs(1,11) : error CS0101: The namespace '<global namespace>' already contains a definition for 'DynaCore'rnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.22.cs(1,5) : error CS0116: A namespace does not directly contain members such as fields or methodsrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.24.cs(1,23) : error CS1518: Expected class, delegate, enum, interface, or structrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.24.cs(1,40) : error CS1001: Identifier expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.24.cs(1,42) : error CS1518: Expected class, delegate, enum, interface, or structrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.26.cs(1,9) : error CS0116: A namespace does not directly contain members such as fields or methodsrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.30.cs(1,10) : error CS0116: A namespace does not directly contain members such as fields or methodsrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.35.cs(1,9) : error CS1022: Type or namespace definition, or end-of-file expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.37.cs(1,5) : error CS1022: Type or namespace definition, or end-of-file expectedrnc:\\Documents and Settings\\simonjef\\Local Settings\\Temp\\mftbafdt.39.cs(1,1) : error CS1022: Type or namespace definition, or end-of-file expected" Source="Compiling" StackTrace: at DynaCode.Program.CompileAndRun(String[] code) in C:\Documents and Settings\simonjef\My Documents\Visual Studio 2008\Projects\Compiling\Compiling\Program.cs:line 72 at DynaCode.Program.Main(String[] args) in C:\Documents and Settings\simonjef\My Documents\Visual Studio 2008\Projects\Compiling\Compiling\Program.cs:line 42 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: ```
