Hi
Im compiling some code at runtime then loading the assembly into the current appdomain, however when i then try to do Type.GetType it cant find the type...
Here is how i compile the code...
public static Assembly CompileCode(string code)
{
Microsoft.CSharp.CSharpCodeProvider provider = new CSharpCodeProvider();
ICodeCompiler compiler = provider.CreateCompiler();
CompilerParameters compilerparams = new CompilerParameters();
compilerparams.GenerateExecutable = false;
compilerparams.GenerateInMemory = false;
foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
{
try
{
string location = assembly.Location;
if (!String.IsNullOrEmpty(location))
{
compilerparams.ReferencedAssemblies.Add(location);
}
}
catch (NotSupportedException)
{
// this happens for dynamic assemblies, so just ignore it.
}
}
CompilerResults results =
compiler.CompileAssemblyFromSource(compilerparams, code);
if (results.Errors.HasErrors)
{
StringBuilder errors = new StringBuilder("Compiler Errors :\r\n");
foreach (CompilerError error in results.Errors)
{
errors.AppendFormat("Line {0},{1}\t: {2}\n",
error.Line, error.Column, error.ErrorText);
}
throw new Exception(errors.ToString());
}
else
{
AppDomain.CurrentDomain.Load(results.CompiledAssembly.GetName());
return results.CompiledAssembly;
}
}
This bit fails after getting the type from the compiled assembly just fine, it does not seem to be able to find it using Type.GetType....
Assembly assem = RuntimeCodeCompiler.CompileCode(code);
string typeName =
String.Format("Peverel.AppFramework.Web.GenCode.ObjectDataSourceProxy_{0}",
safeTypeName);
Type t = assem.GetType(typeName); //This works just fine..
Type doesntWork = Type.GetType(t.AssemblyQualifiedName);
Type doesntWork2 = Type.GetType(t.Name);
....
