入门：刚开始学.Net时写的分页类

public PagedDataSource GetPagedDataSource(DataSet MyDataSet,int PageSize,int PageNum,string AspxName,Label PageLable)
{
PagedDataSource PDS=new PagedDataSource();

PDS.AllowPaging=true;
PDS.PageSize=PageSize;
PDS.DataSource=MyDataSet.Tables[0].DefaultView;

int CurrentPage=0;
if(Convert.ToString(PageNum)!=null)
{
CurrentPage=int.Parse(PageNum.ToString());
}
else
{
CurrentPage=1;
}
PDS.CurrentPageIndex=CurrentPage-1;

int PageCount=PDS.PageCount;

string FirstPage=(PageNum==1)?("9"):("9");
string PrevPage=(PageNum==1)?("7"):("7");
string NextPage=(PageNum==(PageCount))?("8"):("8");
string LastPage=(PageNum==(PageCount))?(":"):(":");

PageLable.Text="总记录: "+PDS.DataSourceCount+"   每页: "+PageSize+"   总页数: "+PageCount+""+FirstPage+"  "+PrevPage+"  "+NextPage+"  "+LastPage+"";

return PDS;
}
调用示例

//PagedDataSource分页

string MySql="Select * from C_Company";
int PageNum=(Request.QueryString["Page"]==null)?(1):(Convert.ToInt32(Request.QueryString["Page"]));
MyDataSet=MyData.GetDataSet(MySql,0,0,"Table");
PagedDataSource PDS=new PagedDataSource();
PDS=MyData.GetPagedDataSource(MyDataSet,10,PageNum,Request.CurrentExecutionFilePath+"?",Label1);
this.DataGrid1.DataSource=PDS;
this.DataGrid1.DataBind();
