SqlCommand Parameterized query problems

such as the following code :
...
string insertsql="INSERT INTO table (id,name) VALUES (@id,@name)";
SqlCommand cmd=new SqlCommand(insertsql,connection);
cmd.Parameters.Add(@id,1);
cmd.Parameters.Add(@name,"benson");

cmd.ExecuteNonQuery();


How do I get a real SQL?  cmd.CommandText get "INSERT INTO table (id,name)
VALUES (@id,@name)",
I hope to have   "INSERT INTO table (id,name) VALUES (1,'benson')"
