问题描述
I have the code below which has multiple DataTables with results and I need to pass a single DataSet with all DataTable values.
MySqlCommand cmd = new MySqlCommand(getLikeInfo, con);
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
MySqlCommand cmd1 = new MySqlCommand(getKnowInfo, con);
MySqlDataAdapter da1 = new MySqlDataAdapter(cmd1);
DataTable dt1 = new DataTable();
da1.Fill(dt1);
MySqlCommand cmd2 = new MySqlCommand(getHotelInfo, con);
MySqlDataAdapter da2 = new MySqlDataAdapter(cmd2);
DataTable dt2 = new DataTable();
da2.Fill(dt2);
MySqlCommand cmd3 = new MySqlCommand(getRoomInfo, con);
MySqlDataAdapter da3 = new MySqlDataAdapter(cmd3);
DataTable dt3 = new DataTable();
da3.Fill(dt3);
MySqlCommand cmd4 = new MySqlCommand(getFoodInfo, con);
MySqlDataAdapter da4 = new MySqlDataAdapter(cmd4);
DataTable dt4 = new DataTable();
da4.Fill(dt4);
How can I do that?
解决方案
DataSet ds = new DataSet();
ds.Tables.Add(dt);
ds.Tables.Add(dt1);
...
If you want your tables named in the DataSet you can create your tables from the DataSet
DataSet ds = new DataSet();
DataTable t1 = ds.Tables.Add("t1"); // Create
DataTable t1Again = ds.Tables["t1"]; // fetch by name
You can also set the TableName property of the tables if you use the first approach.
