What is the easiest way to find out the lastest created file in a directory using C#?

I was puzzed few days ago about sorting the lastest created file in the directory. The methods which i thought of were too complicated having to check the file infomation and do some sorting of the files. Later i thought of some simple way and i believe it is very creative method.

//Code to save the file

string saveImageLocation = @"C:\store";
{
string fileName = DateTime.Now.Ticks + new FileInfo(openFileDialog1.FileName).Name;
if (!File.Exists(saveImageLocation + fileName ))
{
File.Copy(openFileDialog1.FileName, saveImageLocation + fileName);
}
}
catch (DirectoryNotFoundException)
{
Directory.CreateDirectory(saveImageLocation);
}



//Code to retrive the image file.
string saveImageLocation = @"C:\store";
pictureBox2.ImageLocation = Directory.GetFiles(saveImageLocation)[Directory.GetFiles(saveImageLocation).Length - 1];


The main idea is naming the creating file by appending the date to the file name. Since date has it own special character, i would suggest using ticks to represent the date.

How to get my motherboard serial number using C#?

Sometimes we might want to identity the unique user for some purposes by knowing the machine identity they are using. Software licensing for instance, we could use his machine processor Id or motherboard id to uniquely identify them. So here are the tricks: using System.Management; //Get motherboard's serial number ManagementObjectCollection mbsList = null; ManagementObjectSearcher mbs = new ManagementObjectSearcher ("Select * From Win32_ BaseBoard "); mbsList = mbs .Get(); foreach ( ManagementObject mo in mbsList ) { textBox 1.Text = mo[" SerialNumber "]. ToString (); } //Get Processor's Identity ManagementObjectCollection mbsList = null; ManagementObjectSearcher mbs = new ManagementObjectSearcher ("Select * From Win32_processor"); mbsList = mbs .Get(); foreach ( ManagementObject mo in mbsList ) { textBox 1.Text = mo[" ProcessorID "]. ToString (); } Warning, although these are the methods to get the id, I feel that using t

Giant Supermarket in Malaysia is unreliable - Prices always incorrect equals being cheated

Today i went to Giant supermarket to buy somethings. Among the things that i bought are wine and shower shampoo. I found that both prices stated in my bill were incorrect. Lucky i did notice my bill didn't make sense. The bill says wine - RM34.99 ( but Giant says i should pay RM26.99), body shower shampoo - RM6.59 ( Giant says RM5.99). See what the lousy supermarket, this is the third time i experienced these problems and surprisingly again Giant supermarket. if i don't check i will lost total of RM8.50. I had went to the customer service to claim back my money and yet it took me total of 1 hour because of verification this and that. Imagine that those hot item which claims great deal but the billing prices are not the same in fact higher that it claims... definitely, we are the victim to be cheated. So, those of you must be careful to check your bill if you are buying things from Giant. Now i am going to change my mind to Tesco since it just near by Giant (luckily).... no mor
