如何在 C# 中将多个 DataTable 存储到单个 DataSet 中?
我有下面的代码,其中有多个带有结果的数据表,我需要传递一个包含所有数据表值的数据集。
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);
我怎样才能做到这一点?
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?

如果您希望在数据集中命名表,则可以从数据集中创建表。
如果使用第一种方法,还可以设置表的
TableName
属性。If you want your tables named in the DataSet you can create your tables from the DataSet
You can also set the
TableName
property of the tables if you use the first approach.
