BytecodeApi implements lots of extensions and classes for general purpose use. In addition, specific classes implement more complex logic for both general app development as well as for WPF apps.

Especially, boilerplate code that is known to be part of any Core DLL in a C# project is likely to be already here. In fact, I use this library in many of my own projects. For this reason, each class and method has been reviewed numerous times.

BytecodeApi is highly consistent, particularly in terms of structure, naming conventions, patterns, etc. The entire code style resembles the patterns used in the .NET Framework itself. You will find it intuitive to understand.

Documentation can be taken for granted! All classes and members have XML tags. The online documentation makes it easy to find the class or method you are looking for.


Following examples are a very brief overview over what features you can come to expect. However, the entire framework covers a lot more. Please review the online documentation to get a complete overview.

Example: Advanced conversion

// Additional conversion methods:

byte[] structBytes = ConvertEx.StructureToArray(myStruct);
MyStruct myStruct = ConvertEx.ArrayToStructure<MyStruct>(structBytes);
string excelColumn = ConvertEx.ToExcelColumnString(1); // <-- "A"

string hexString = ConvertEx.ToHexadecimalString(byteArray);

Example: Thread-safe access (Atomic)

Atomic<MyClass> ThreadSafeObj = new Atomic<MyClass>();

// Access an object in a thread-safe manner:
ThreadSafeObj.Value.Foo = 123;

// Or exchange the object:
ThreadSafeObj.Exchange((oldObject) => // <-- The current MyClass instance
	return new MyClass(); // <-- the new MyClass instance to replace "oldObject".

// Call a method, while the object is locked:
int result = ThreadSafeObj.Lock((obj) => obj.GetInteger());

// ...

public class MyClass
	public int Foo;

	public int GetInteger()
		return 0;

Example: CSV parsing

CsvFile file = CsvFile.FromFile(path: @"C:\test.csv", delimiter: null, hasHeaderRow: true);

// delimiter: null means auto-detect!

foreach (CsvRow row in file.Rows)
	int? id = row["A"].Int32Value;
	string name = row["B"].Value;

// And for the fans or victims of "CSV extreme databasing"
// This IEnumerable will iterate over the CSV file
IEnumerable<CsvRow> largeCsv = CsvFile.EnumerateFile(@"C:\very_large_file.csv", null, true);

Example: Advanced File I/O

// Find a string in a file
long index = FileEx.FindSequence(@"C:\test.txt", "search_me".ToUTF8Bytes());
if (index != -1)
	// ...

// FileEx extends the System.IO.File class.

Example: HTTP GET & POST request handling

// HttpClient implements GET and POST requests and returns a byte[] or a string.
HttpClient client = new HttpClient();

byte[] file = client.PostBytes("", new[]
	new PostValue("fileID", "123"),
	new PostValue("convert", "1")

Example: WMI wrapper class

// Read WMI objects using the BytecodeApi.IO.Wmi namespace:
WmiObject[] processes = new WmiNamespace("CIMV2")

Example: Compression

byte[] file = File.ReadAllBytes("C:\\test.txt");

// Easily compress and decompress binary data:
byte[] compressed = Compression.Compress(file);
byte[] decompressed = Compression.Decompress(compressed);

Example: Cryptography

byte[] file = File.ReadAllBytes(@"C:\test.txt");

// Encrypt and decrypt binary content using a password.
byte[] encrypted = ContentEncryption.Encrypt(file, "123456");
byte[] decrypted = ContentEncryption.Decrypt(encrypted, "123456");

// Test using a the byte[] extension method:
if (!encrypted.Compare(decrypted)) throw new Exception();

// The "ContentEncryption" class uses
//     byte[] Encryption.Encrypt(byte[] data, byte[] iv, byte[] key)
// in conjunction with the SHA-256 converted password.

// Hash examples:
string passwordHash = Hashes.Compute("123456", HashType.SHA256);
string fileHash = Hashes.Compute(file, HashType.SHA256);

Example: DLL injection

Process process = ProcessEx.GetSessionProcessesByName("TaskMgr").First();

// Inject my wonderful ring-3 rootkit into your task manager.

// Project r77:

Example: ViewModel base class (INotifyPropertyChanged)

public class MyViewModel : ObservableObject
	// An MVVM property for the ViewModel.
	// Strongly typed and as simple as it gets:
	public string Foo
		get => Get(() => Foo);
		set => Set(() => Foo, value);
		// INotifyPropertyChanged -^
