.net 多个数据库事务处理

TranscationScope用法示例

//标记是否已执行接口库中的操作

bool isYiZhiXingInterface = false;

using (TransactionScope transScope = new TransactionScope())

{

DataBase dbLocal = new DataBase(_connectionString);

DataBase dbInterface = new DataBase(_connectionStringInterface);

try

{

dbLocal.BeginTrans();

dbInterface.BeginTrans();

dbLocal.RunSqlNonQuery_Trans(strSql);

dbInterface.RunSqlNonQuery_Trans(strSqlInterface);

isYiZhiXingInterface = true;

}

catch(System.Data.SqlClient.SqlException ex)

{

dbLocal.RollBack();

if (isYiZhiXingInterface)

dbInterface.RollBack();

dbLocal.Dispose();

dbInterface.Dispose();

throw ex;

}

dbLocal.Commit();

dbInterface.Commit();

transScope.Complete();

dbLocal.Dispose();

dbInterface.Dispose();

transScope.Dispose();

}
