I have been itching to program in C# for a long time now.. finally got a chance to try it out due to requirement at work. Here’s a small snippet of code that does a bunch of things
1) Opens a directory and get a list of files in it
2) Parses the file name into multiple variables
3) Connects to Active Directory and gets properties for a user
4) Creates an error file with list of errors.
5) Creat an output file in csv format.

For the programming gurus out there, this should be pretty easy :).. I am sure that there are tons of errors in the way, I wrote the code, but this is a beginning :).

using System;
using System.Collections.Generic;

using System.IO;
using System.DirectoryServices;

namespace sortAssetData
{
class Program
{
static void Main(string[] args)
{
// Create a Log file and output file

System.IO.TextWriter infoLog = new System.IO.StreamWriter(“sortAssetDataLog.txt”);
System.IO.TextWriter outputLog = new System.IO.StreamWriter(“finalAssetData.csv”);

// Write the column headers into the output file
outputLog.WriteLine(“Last_Name, First_Name, Display_Name, Batt_Check_Version, Model_Type, Model_Number, Serial_Number, Batt_Manufacturer, Batt_Model, Batt_Serial_Number, Affected”);

// Define the folder where the data files are sitting
string fixDirectoy = “P:\\BatteryCheck_Results”;

// Change working directory to the folder with all the files
System.IO.Directory.SetCurrentDirectory(fixDirectoy);

// Create a directory object to get list of asset files
System.IO.DirectoryInfo tempDirObject = new System.IO.DirectoryInfo(fixDirectoy);

// Get list of *.csv files in the asset folder
System.IO.FileInfo[] listOfFiles = tempDirObject.GetFiles(“*.csv”);

// Process each file in the directory
foreach (System.IO.FileInfo tempFile in listOfFiles)
{
// Display the current file that is being processed
System.Console.WriteLine(“Processing : {0}”, tempFile.Name);
infoLog.WriteLine(“Processing : {0}”, tempFile.Name);
infoLog.Flush();

// Split the file name into Domain, Hostname, Username
string tempData = tempFile.Name;
// Removing the .csv at the end of the file name
tempData = tempData.Replace(“.csv”, “”);
string[] sortData = tempData.Split(new Char[] { ‘_’ });

// If file name doesn’t contain 3 records (Domain, ComputerName and UserName), we ignore it
if (sortData.Length != 3)
{
infoLog.WriteLine(“ERROR : Bad file format : {0}”, tempFile.Name);
infoLog.Flush();
continue;
}

// Display the userdata we got from the file name
System.Console.WriteLine(“\nDomain :\t {0}”, sortData[0]);
System.Console.WriteLine(“Computer Name :\t {0}”, sortData[1]);

searchUser.Filter = String.Format(“(SAMAccountName={0})”, sortData[2]);
searchUser.PropertiesToLoad.Add(“cn”);
searchUser.PropertiesToLoad.Add(“givenname”);
searchUser.PropertiesToLoad.Add(“sn”);
System.DirectoryServices.SearchResult resultFromAD = searchUser.FindOne();

// If the username doesn’t have a AD account, note and skip to the next file
if (resultFromAD == null)

System.IO.StreamReader tempSoureFile = new System.IO.StreamReader(tempFile.Name);
