使用事务：

//BCP copy
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "server=.;uid=dmkj_hpc;pwd=#$wlh*&1110h%c;database=DMKJ_SMS";
conn.Open();

SqlTransaction sqlbulkTransaction = conn.BeginTransaction();

//请在插入数据的同时检查约束，如果发生错误调用sqlbulkTransaction事务
SqlBulkCopy copy = new SqlBulkCopy(conn, SqlBulkCopyOptions.CheckConstraints, sqlbulkTransaction);

copy.DestinationTableName = "T_SMS_SendInfo";
foreach (DataColumn dc in dataTable.Columns)
{
copy.ColumnMappings.Add(dc.ColumnName, dc.ColumnName);

}
try
{
copy.WriteToServer(dataTable);
sqlbulkTransaction.Commit();
}
catch (Exception ex)
{
sqlbulkTransaction.Rollback();
Console.WriteLine(ex.ToString());
}
finally
{
copy.Close();
conn.Close();
}
