主要实现页面跳转、动态改变每页显示行数、返回首末页、上下页功能，效果图如下：

主代码如下：

namespace Paging
{
 
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        private int currentPageCount;//记录当前页行数
 
        private int pageCount;//记录总页数
 
        private int currentCount;//记录当前页数
 
        private void Form1_Load(object sender, EventArgs e)
        {
            currentPageCount = Convert.ToInt32(txt_lines.Text);
            string sql = "select*from StudentInfo";
            DataSet ds = ConnectClass.ReturnDataSet(sql);
            Paging(ds);
            
        }
 
        private void Paging(DataSet ds)
        {
            int pageLine = 0;
            int count = ds.Tables[0].Rows.Count;//总行数
            lb_recordNum.Text = count.ToString();
            pageCount = Convert.ToInt32(Math.Ceiling(Convert.ToDouble(count) / currentPageCount));
            if (count > currentPageCount)
                pageLine = currentPageCount;
            else
                pageLine = count;
            this.currentCount = 1;
            Binds();
        }
 
        private void btn_Click(object sender, EventArgs e)
        {
            Button btn = sender as Button;
            string tag = btn.Tag.ToString();//获取首页、上一页、下一页、末页的tag属性值
            switch (tag)
            {
                case "0"://首页
                    this.currentCount = 1;
                    break;
                case "1"://上一页
                    this.currentCount -= 1;
                    break;
                case "2"://下一页
                    this.currentCount += 1;
                    break;
                case "3"://末页
                    this.currentCount = this.pageCount;
                    break;
            }
            Binds();
        }
 
        private void Binds()
        {
            string sql = string.Empty;
            if (this.currentCount.Equals(0))
            {
                currentCount = 1;
                MessageBox.Show("当前已是首页");
            }
            else if (this.currentCount.Equals(pageCount + 1))
            {
                this.currentCount = this.pageCount;
                MessageBox.Show("当前已是末页");
            }
            else if (this.currentCount > 0 && this.currentCount < pageCount + 1)
            {
                sql = ConnectClass.ReturnSelectSql(currentPageCount, (currentCount - 1) * currentPageCount);
                DataSet ds = ConnectClass.ReturnDataSet(sql);
                this.dataGridView1.DataSource = ds.Tables[0];
                lb_page.Text = this.currentCount + " / " + pageCount;
            }
        }
        //跳转页面
        private void btn_jump_Click(object sender, EventArgs e)
        {
            if (txt_page.Text == "")
                return;
            this.currentCount = Convert.ToInt32(txt_page.Text);
            if (this.currentCount > 0 && this.currentCount < pageCount + 1)
                Binds();
        }
        //设置每行页数
        private void txt_lines_Leave(object sender, EventArgs e)
        {
            Form1_Load(sender, e);
        }
 
    }
}

ConnectClass类文件代码如下：

namespace Paging
{
    class ConnectClass
    {
        private static string sqlCon = "Data source=.;Initial Catalog=StudentInfo;Integrated Security=True;";
        private static SqlConnection conn = new SqlConnection(sqlCon);
 
        public static DataSet ReturnDataSet(string sql)
        {
            conn.Open();
            DataSet ds = new DataSet();
            SqlDataAdapter sda = new SqlDataAdapter(sql, conn);
            sda.Fill(ds, "objDataSet");
            conn.Close();
            return ds;
        }
 
        public static string ReturnSelectSql(int count,int totalCount)
        {
            string sql = "select top " + count + " * from StudentInfo where id not in (select top " + totalCount + " id from StudentInfo) ";
            return sql;
        }
    }
}
