Example

Encryption encryption = new Encryption(); //Trial Mode
//Encryption encryption = new Encryption("place user name here", "place license key here"); //License Mode
 
string path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TestDirectory");
Directory.CreateDirectory(path);
 
string testFile = Path.Combine(path, "testfile.txt");
File.WriteAllText(testFile, "This is a test");
 
string nonMatchingFile = Path.Combine(path, "testfile.log");
File.WriteAllText(nonMatchingFile, "This is a test");
 
encryption.SecureDirectoryErase(path, "*.txt");
 
bool fileExists = File.Exists(testFile);
Console.WriteLine("Matching File Exists: {0}", fileExists);
 
fileExists = File.Exists(nonMatchingFile);
Console.WriteLine("Non Matching File Exists: {0}", fileExists);

VB.NET

Dim encryption As New Encryption() 'Trial Mode
'Dim encryption As New Encryption("place user name here", "place license key here") 'License Mode
 
Dim path As String = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TestDirectory")
Directory.CreateDirectory(path)
 
Dim testFile As String = Path.Combine(path, "testfile.txt")
File.WriteAllText(testFile, "This is a test")
 
Dim nonMatchingFile As String = Path.Combine(path, "testfile.log")
File.WriteAllText(nonMatchingFile, "This is a test")
 
encryption.SecureDirectoryErase(path, "*.txt")
 
Dim fileExists As Boolean = File.Exists(testFile)
Console.WriteLine("Matching File Exists: {0}", fileExists)
 
fileExists = File.Exists(nonMatchingFile)
Console.WriteLine("Non Matching File Exists: {0}", fileExists)
