Can any one help me in understanding the error raised on the InvokeMember method:

System.Reflection.TargetInvocationException - Exception has been thrown by the target of an invocation.
InnerException - Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done. {System.Runtime.InteropServices.COMException}

C#

//var conStr = GetConnectionString(strFileOutput, String.Empty);
var conStr = @"Provider=Microsoft.ACE.OLEDB.12.0;Extended Properties=Access 12.0;";
conStr += "Data Source=C:\\test.accdb;Persist Security Info=False;";

var catType = Type.GetTypeFromProgID("ADOX.Catalog");

object obj = Activator.CreateInstance(catType);

catType.InvokeMember("Create", BindingFlags.InvokeMethod, null, obj, new object[] { conStr });

OleDbConnection cnn = new OleDbConnection(conStr);

cnn.Open();

Try this:

C#

using System;
 using ADOX;

 namespace ConsoleApplication1
 {
     class Class1
     {
         [STAThread]
         static void Main(string[] args)
         {
             ADOX.Catalog cat = new ADOX.Catalog();

             cat.Create("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\test.accdb;");

             Console.WriteLine("Database Created Successfully");

             cat = null;

         }
     }
 }

I would avoid the Activator and setting through reflection if you don't need to. I think the error you are getting is because it's trying to create a connection with a lot of properties set on a database that doesn't exist. You need to simplify your connection string, then when you want to open it you can use the rest of the properties.
