求救，事务问题！！！

[pp4u]

我用sqldataadapter将四个表添加进一个dataset数据库，更新每个数据库时为防止失败，想用事务，可怎样将sqldataadapter和事务连起来？？？

sdk文档中有的，我复制给你算了:)

SqlConnection myConnection = new SqlConnection("Data Source=localhost;Initial Catalog=Northwind;Integrated Security=SSPI;");
myConnection.Open();

// Start a local transaction.
SqlTransaction myTrans = myConnection.BeginTransaction();

// Enlist the command in the current transaction.
SqlCommand myCommand = new SqlCommand();
myCommand.Transaction = myTrans;

try
{
myCommand.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
myCommand.ExecuteNonQuery();
myCommand.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
myCommand.ExecuteNonQuery();
myTrans.Commit();
Console.WriteLine("Both records are written to database.");
}
catch(Exception e)
{
myTrans.Rollback();
Console.WriteLine(e.ToString());
Console.WriteLine("Neither record was written to database.");
}
finally
{
myConnection.Close();
}

我用的是sqlcommandbuilder+sqldataadapter+dataset，能不能给我源码?
