DataTable tblDatas = new DataTable( "Datas" );
DataColumn dc = null ;
dc = tblDatas.Columns.Add( "ID" , Type.GetType( "System.Int32" ));
dc.AutoIncrement = true ; //自动增加
dc.AutoIncrementSeed = 1; //起始为1
dc.AutoIncrementStep = 1; //步长为1
dc.AllowDBNull = false ; //
dc = tblDatas.Columns.Add( "Product" , Type.GetType( "System.String" ));
dc = tblDatas.Columns.Add( "Version" , Type.GetType( "System.String" ));
dc = tblDatas.Columns.Add( "Description" , Type.GetType( "System.String" ));
DataRow newRow; newRow = tblDatas.NewRow(); newRow[ "Product" ] = "水果刀" ;
newRow[ "Version" ] = "2.0" ;
newRow[ "Description" ] = "打架专用" ;
tblDatas.Rows.Add(newRow); newRow = tblDatas.NewRow(); newRow[ "Product" ] = "折叠凳" ;
newRow[ "Version" ] = "3.0" ;
newRow[ "Description" ] = "行走江湖七武器之一" ;
tblDatas.Rows.Add(newRow); |
