C#显示事务

using System.Data.SqlClient;
using System.Transactions;

// 这里写查询代码

// 获取Web.config文件中数据库连接字符串
string connectionString = ConfigurationSettiongs.AppSettings["ConnectionString"];
using(SqlConnection connection = new SqlConnection(connectionString)){
  connection.Open();

  SqlCommand command = connection.CreateCommand();
  SqlTransaction transaction = connection.BeginTransaction();

  command.Connection = connection;
  command.Transaction = transaction;

  try{
    //这里写增删改代码
    transaction.Commit();
  }
  catch(Exception e){
    transaction.Rollback();
  }
  finally{
    connection.Close();
  }
}

注意：此事务方法适合单个数据库使用，若多库请使用分布式显示事务CommittableTransaction
请参考博客.NET事务
