C#编程实现DataTable添加行的方法

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:

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:

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。
