这篇文章主要介绍了C#中事务处理和非事务处理方法,较为详细的分析了C#中事务处理与非事务处理的使用技巧,对于使用C#进行数据库程序开发有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#中事务处理和非事务处理方法。分享给大家供大家参考。具体如下:
C#代码如下:
- String connectionString = ConfigurationManager.ConnectionStrings["DB_Constr"].ToString();
- SqlConnection conn = null;
- SqlTransaction trans = null;
- try {
- conn = new SqlConnection(connectionString);
- if (conn.State != ConnectionState.Open) conn.Open();
- //开启事务,可以指定事无级别。默认为提交才可以查询
- trans = conn.BeginTransaction();
- //save(conn, trans);
- DbUtils.commit(trans);
- } catch (Exception ex) {
- DbUtils.rollback(trans);
- ClientScript.RegisterStartupScript(this.GetType(), "错误提示", "<script>alert('" + StringUtil.toJsStr(ex.Message) + "');</script>");
- } finally {
- DbUtils.closeQuietly(conn, trans);
- }
- String connectionString = ConfigurationManager.ConnectionStrings["DB_Constr"].ToString();
- SqlConnection conn = null;
- try {
- conn = new SqlConnection(connectionString);
- if (conn.State != ConnectionState.Open) conn.Open();
- } catch (Exception ex) {
- ScriptManager.RegisterStartupScript(this, this.GetType(), "mess", "<script>alert('"+StringUtil.toJsStr(ex.Message)+"')</script>", false);
- } finally {
- DbUtils.closeQuietly(conn);
- }
StringUtil.cs如下:
- using System;
- using System.Collections.Generic;
- using System.Text;
- namespace Tools{
- public sealed class StringUtil {
- public static bool isEmpty(String str) {
- if (str == null) return true;
- if (str.Length == 0) return true;
- if (str == String.Empty) return true;
- return false;
- }
- public static bool isNotEmpty(String str) {
- return !isEmpty(str);
- }
- public static String toJsStr(String str) {
- str = str.Replace("'", "//'");
- str = str.Replace("/r", "");
- str = str.Replace("/n", "//n");
- return str;
- }
- public static void Main() {
- Console.Write(isNotEmpty(null));
- Console.Read();
- }
- }
- }
DbUtils.cs如下:
- using System;
- using System.Collections.Generic;
- using System.Text;
- using System.Data.SqlClient;
- using System.Data;
- namespace Tools{
- public class DbUtils {
- public static SqlConnection getConnection(string connectstr) {
- SqlConnection conn = new SqlConnection(connectstr);
- if (conn.State != ConnectionState.Open) {
- conn.Open();
- }
- return conn;
- }
- public static void closeQuietly(SqlConnection conn) {
- try {
- close(conn);
- } catch { }
- }
- public static void closeQuietly(SqlTransaction trans) {
- try {
- close(trans);
- } catch { }
- }
- public static void close(SqlConnection conn) {
- if (conn != null) {
- conn.Close();
- conn.Dispose();
- }
- }
- public static void close(SqlTransaction trans) {
- if (trans != null) {
- trans.Dispose();
- }
- }
- public static void closeQuietly(SqlConnection conn, SqlTransaction trans) {
- closeQuietly(trans);
- closeQuietly(conn);
- }
- public static void commit(SqlTransaction trans) {
- try {
- if(trans!=null) trans.Commit();
- } catch{ }
- }
- public static void rollback(SqlTransaction trans) {
- try {
- if (trans != null) trans.Rollback();
- } catch { }
- }
- }
- }
希望本文所述对大家的C#程序设计有所帮助。
