推荐答案

SqlDataAdapter.Fill方法具有一个以DataTable作为参数的重载.您可以使用多个Fill命令来填充多个表，然后将这些表添加到单个数据集中.像这样的东西:

Hi,

The SqlDataAdapter.Fill methos has an overload that takes DataTable as parameter. You can use multiple Fill commands to fill multiple tables and then add these tables to single dataset. Something like :

DataSet ds = new DataSet();
            DataTable dt = new DataTable("Employee");
            SqlDataAdapter da = new SqlDataAdapter();
            //Add some command
            //Finally call fill
            da.Fill(dt);
            ds.Tables.Add(dt);

            SqlDataAdapter da1 = new SqlDataAdapter();
            DataTable dt1 = new DataTable("Department");
            //Add some command
            //Finally call fill
            da1.Fill(dt1);
            ds.Tables.Add(dt1);

希望对您有所帮助:)
