create a table in sql from an asp.net app

I've never done it, but I'd imagine that you'd just need to send the "CREATE TABLE" script through a SqlCommand, such as:

SqlConnection sqlConn = new SqlConnection(strSqlConnection);
string strSql = "CREATE TABLE ... ";
SqlCommand sqlCmd = new SqlCommand(strSql, sqlConn);
sqlCmd.Connection.Open();
sqlCmd.ExecuteNonQuery();
sqlCmd.Connection.Close();

That should work.
