关于.net动态调用websercie时，webservice操作类

string @namespace = "ServiceBase.WebService.DynamicWebLoad";
if ((classname == null) || (classname == ""))
{
classname = WSHelper.GetWsClassName(url);
}
try
{ //获取WSDL
//获取服务描述语言(WSDL)
WebClient wc = new WebClient();
Stream stream = wc.OpenRead(url + "?WSDL");
ServiceDescription sd = ServiceDescription.Read(stream);
ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();
sdi.AddServiceDescription(sd, "", "");
CodeNamespace cn = new CodeNamespace(@namespace);
//生成客户端代理类代码
CodeCompileUnit ccu = new CodeCompileUnit();
ccu.Namespaces.Add(cn);
sdi.Import(cn, ccu);
CSharpCodeProvider csc = new CSharpCodeProvider();
ICodeCompiler icc = csc.CreateCompiler();
//设定编译器的参数
CompilerParameters cplist = new CompilerParameters();
cplist.GenerateExecutable = false;
cplist.GenerateInMemory = true;
cplist.ReferencedAssemblies.Add("System.dll");
cplist.ReferencedAssemblies.Add("System.XML.dll");
cplist.ReferencedAssemblies.Add("System.Web.Services.dll");
cplist.ReferencedAssemblies.Add("System.Data.dll");
//编译代理类
CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);
if (true == cr.Errors.HasErrors)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors)
{
sb.Append(ce.ToString());
sb.Append(System.Environment.NewLine);
}
throw new Exception(sb.ToString());
}
//生成代理实例，并调用方法
System.Reflection.Assembly assembly = cr.CompiledAssembly;
Type t = assembly.GetType(cn + "." + classname, true, true);
object obj = Activator.CreateInstance(t);
System.Reflection.MethodInfo mi = t.GetMethod(methodname);
return mi.Invoke(obj, args);
// PropertyInfo propertyInfo = type.GetProperty(propertyname);
//return propertyInfo.GetValue(obj, null);
}
catch (Exception ex)
{
throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace));
}
调用此方法是，执行到 System.Reflection.Assembly assembly = cr.CompiledAssembly;
Type t = assembly.GetType(cn + "." + classname, true, true);时出问题，提示错误

未能从程序集“f4h444sz, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null”中加载类型“System.CodeDom.CodeNamespace.ConferenceWebService”。

什么错误？？我开发工具vs2013
