using System;
using System.Configuration;
using System.Data.SqlClient;
using System.Data;
using System.Collections;
比如:
// 打开数据库
public static SqlConnection OpenConnection()
{
SqlConnection mysqlConn = new SqlConnection(ConfigurationSettings.AppSettings["connstring"]);
try
{
mysqlConn.Open();
}
catch (Exception e)
{
//rethrow this exception
throw e;
}return mysqlConn;
}// 执行SQL返回DataSet
public static DataSet GetDataSet(string SQLQuery)
{
SqlConnection cn = DBObject.OpenConnection();
SqlDataAdapter da = new SqlDataAdapter(SQLQuery, cn);
DataSet ds = new DataSet();
da.Fill(ds);
//release resources
da.Dispose();
da = null;
cn.Close();
cn = null;return ds;
}// 执行SQL语句
public static void ExecuteUpdateQuery(string SQLQuery)
{
SqlConnection cn = DBObject.OpenConnection();
SqlCommand cmd = new SqlCommand();cmd.CommandText = SQLQuery;
cmd.CommandType = CommandType.Text;
cmd.Connection = cn;
cmd.ExecuteNonQuery();
cn.Close();
cn = null;
