手動建立DataSet的方式

DataSet setFromDatabase = new DataSet();

DataTable dataTable = new DataTable();

DataColumn dataColumn;

dataColumn = new DataColumn("title");

dataColumn.DataType = Type.GetType("System.String");

dataTable.Columns.Add(dataColumn);

dataColumn = new DataColumn("content");

 dataColumn.DataType = Type.GetType("System.String");

 dataTable.Columns.Add(dataColumn);

dataColumn = new DataColumn("url");

 dataColumn.DataType = Type.GetType("System.String");

 dataTable.Columns.Add(dataColumn);

 dataColumn = new DataColumn("updateTime");

 dataColumn.DataType = Type.GetType("System.DateTime");

dataTable.Columns.Add(dataColumn);

 DataRow dataRow;

dataRow = dataTable.NewRow(); dataRow["title"] = "華羅庚誕辰100週年紀念會暨應用數學學術思想研討會舉行";

dataRow["content"] = "9月12日，由中科院研究生院主辦的“華羅庚誕辰100周 "; dataRow["url"] = http://www.gucas.ac.cn/gucascn/Presentation/TopNews.aspx?ContentID=9547;

 dataRow["updateTime"] = System.DateTime.Now;

 dataTable.Rows.Add(dataRow);
