C#添加日志文件——简洁（部署IIS也可以生成日志）

//记录日志
public static void WriteLog(string str)
{
	//获取应用程序的当前工作目录
	string filePath = AppDomain.CurrentDomain.BaseDirectory + "Log\\";
	if (!Directory.Exists(filePath))
	{
		Directory.CreateDirectory(filePath);
	}
	filePath = filePath + DateTime.Now.ToString("yyyy-MM-dd") + ".log";
	using (StreamWriter streamWriter = new StreamWriter(filePath, append: true, Encoding.UTF8))
	{
		streamWriter.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss ") + str);
		streamWriter.Close();
		streamWriter.Dispose();
	}
}
