i have a dll in vb6 which i use to call in c#(vs2008) like this

add reference

C#

PrjMainO.ClsMainClass ClsSAGMainO = new PrjMainO.ClsMainClass();

object myobj = new object();
bool x = false;
string strvalue= ClsSAGMainO.InitProdNew("myAppname",  "Logger.Log",  2014, ref str, ref x);

Now i want to call the function in this manner

C#

object objrval = new object();
           objrval = 0;

           object[] oparam = new object[] { "myAppname",  "Logger.Log",  2014 };
           object objJRO = Activator.CreateInstance(Type.GetTypeFromProgID("PrjMainO.ClsMainClass"));
           objrval= objJRO.GetType().InvokeMember("InitProdNew",
               System.Reflection.BindingFlags.InvokeMethod,
               null,
               objJRO,
              oparam);
           string strvalue= Convert.ToString(objrval);

// Create an array containing the arguments. object[] args = {"Argument 1", "Argument 2", "Argument 3" };

// Initialize a ParameterModifier with the number of parameters. ParameterModifier p = new ParameterModifier(3);

// Pass the first and third parameters by reference. p[0] = true; p[2] = true;

// The ParameterModifier must be passed as the single element // of an array. ParameterModifier[] mods = { p };

// Invoke the method late bound. obj.GetType().InvokeMember(" MethodName", BindingFlags.InvokeMethod, null, obj, args, mods, null, null);
