C#中事务处理和非事务处理方法实例分析
作者：罪恶的花生
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。
