Reusing SqlCommand?

Question

I am not really sure if this is possible or not.

I am currently working on a college project and I have a function that uses stored procedures. I would like to know

Yes. You'll want to make sure that you call myCommand.Parameters.Clear between each call in order to dump the parameters, but there's nothing stopping you from reusing the object. (I don't use C# often, so this may have an error or two in the text)

myConStr = ConfigurationManager.ConnectionStrings["MyConnString"].ConnectionString;
myConn = new SqlConnection(myConStr);
myConn.Open();

myCommand = new System.Data.SqlClient.SqlCommand("team5UserCurrentBooks3", myConn); 
myCommand.CommandType = CommandType.StoredProcedure;
myCommand.Parameters.AddWithValue("@book_id", bookID);
myCommand.Parameters.AddWithValue("@user_id", userID);
myCommand.ExecuteNonQuery();

myCommand.Parameters.Clear();
myCommand.CommandText= "NewStoredProcedureName";
myCommand.CommandType = CommandType.StoredProcedure;
myCommand.Parameters.AddWithValue("@foo_id", fooId);
myCommand.Parameters.AddWithValue("@bar_id", barId);
mycommand.ExecuteNonQuery();

myCommand.Parameters.Clear();
myCommand.CommandText = " SELECT * FROM table1 WHERE ID = @TID;"
myCommand.CommandType = CommandType.Text;
myCommand.Parameters.AddWithValue("@tid", tId);
SqlReader rdr;
rdr = myCommand.ExecuteReader();
