本文实例讲述了C#编程实现DataTable添加行的方法。分享给大家供大家参考,具体如下:
方法一:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | 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); |
方法二:
1 2 3 4 5 6 7 8 9 10 11 12 13 | DataTable tblDatas = new DataTable( "Datas" ); tblDatas.Columns.Add( "ID" , Type. GetType ( "System.Int32" )); tblDatas.Columns[0].AutoIncrement = true; tblDatas.Columns[0].AutoIncrementSeed = 1; tblDatas.Columns[0].AutoIncrementStep = 1; tblDatas.Columns.Add( "Product" , Type. GetType ( "System.String" )); tblDatas.Columns.Add( "Version" , Type. GetType ( "System.String" )); tblDatas.Columns.Add( "Description" , Type. GetType ( "System.String" )); tblDatas.Rows.Add( new object[]{null, "a" , "b" , "c" }); tblDatas.Rows.Add( new object[] { null, "a" , "b" , "c" }); tblDatas.Rows.Add( new object[] { null, "a" , "b" , "c" }); tblDatas.Rows.Add( new object[] { null, "a" , "b" , "c" }); tblDatas.Rows.Add( new object[] { null, "a" , "b" , "c" }); |
希望本文所述对大家C#程序设计有所帮助。
