C#:DataTable添加行的方法

这个…我就不说了吧。纯粹是写着玩的

方法一:

代码
   
     
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:

 

代码
   
     
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 " });
