//记录执行过的sql语句到txt文本中

public void WriteSQLLog(string strExp)
{
try
{
string path = AppDomain.CurrentDomain.BaseDirectory.ToString();
path = path + "SQL/";

if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}

FileStream fs = new FileStream(path + "sql_log.log", FileMode.Append);
StreamWriter sw = new StreamWriter(fs);
sw.Write("[" + DateTime.Now.ToString("yyy-MM-dd HH:mm:ss") + "]" + strExp + "\r\n");
sw.Flush();
sw.Close();
}
