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 :).

// 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)
{

if (sortData.Length != 3)
