access数据库的分页显示的C#代码
最近在做C#开发的winform应用，只用到access数据库，数据量稍微有点多，需要分页显示，在网上看到很多都是给出了一个sql查询语句，但是没有具体的C#代码的操作实例，哪位达人能够提供一下access数据库分页显示的C#代码？就是C#对sql语句的操作过程。。。谢谢 --------------------编程问答----------------------------------------编程问答--------------------
public class DBHelper
{
//属性:数据库链接对象
private static OleDbConnection conn;
public static OleDbConnection Conn
{
get
{
try
{
string connstr = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source=" + "" + Application.StartupPath + @"\Database.mdb";
if (conn == null)
conn = new OleDbConnection(connstr);
if (conn.State == ConnectionState.Closed)
conn.Open();
if (conn.State == ConnectionState.Broken)
{
conn.Close();
conn.Open();
}
return conn;
}
catch (Exception ex)
{
throw;
}
}
}
//方法:查询,DataReader
public static OleDbDataReader GetReader(string SqlStr)
{
OleDbCommand cmd = new OleDbCommand(SqlStr, Conn);
return cmd.ExecuteReader();
}
public static OleDbDataReader GetReader(string SqlStr, OleDbParameter[] paras)
{
OleDbCommand cmd = new OleDbCommand(SqlStr, Conn);
cmd.Parameters.AddRange(paras);
return cmd.ExecuteReader();
}
//查询:DataTable
public static DataTable GetTable(string SqlStr)
{
try
{
OleDbDataAdapter dap = new OleDbDataAdapter(SqlStr, Conn);
DataSet ds = new DataSet();
dap.Fill(ds);
conn.Close();
return ds.Tables[0];
}
catch (Exception ex)
{
throw;
}
}
//增删改
public static bool Execute(string SqlStr)
{
OleDbCommand cmd = new OleDbCommand(SqlStr, Conn);
int result = cmd.ExecuteNonQuery();
conn.Close();
return result > 0;
}
/// <summary>
/// 向数据库里插入图像格式的字段(和上面情况类似的另一种实例)
/// </summary>
/// <param name="strSQL">SQL语句</param>
/// <param name="fs">图像字节,数据库的字段类型为image的情况</param>
/// <returns>影响的记录数</returns>
public static int Execute(string SqlStr, byte[] photo)
{
OleDbCommand cmd = new OleDbCommand(SqlStr, Conn);
OleDbParameter myParameter = new OleDbParameter("@photo", SqlDbType.Image);
myParameter.Value = photo;
cmd.Parameters.Add(myParameter);
int result = cmd.ExecuteNonQuery();
return result;
}
//返回首行首列
public static object GetScalar(string SqlStr)
{
OleDbCommand cmd = new OleDbCommand(SqlStr, Conn);
object obj = cmd.ExecuteScalar();
conn.Close();
return obj;
}
我要的是分页的代码，不仅仅是操作数据库的代码？ --------------------编程问答--------------------
你看看你帖子的最后一句，就是C#对sql语句的操作过程
补充：.NET技术 , C#
