这个答案向您展示了如何执行字节数组。 一个警告，这可能会导致病毒扫描程序出现问题，因为它在恶意软件中很常见。

如果你不想从内存执行，我提出了一个如何加密存储然后解密并运行可执行文件的例子。

上述就是C#学习教程：如何使用C＃加密另一个程序？分享的全部内容，如果对大家有所用处且需要了解更多关于C#学习教程，希望大家多多关注—计算机技术网(www.ctvol.com)!

public class FileEncryptRunner { Byte[] key = ASCIIEncoding.ASCII.GetBytes("thisisakeyzzzzzz"); Byte[] IV = ASCIIEncoding.ASCII.GetBytes("thisisadeltazzzz"); public void SaveEncryptedFile(string sourceFileName) { using (FileStream fStream = new FileStream(sourceFileName, FileMode.Open, FileAccess.Read, FileShare.Read), outFStream = new FileStream(Environment.SpecialFolder.MyDocuments+"test.crp", FileMode.Create)) { Rijndael RijndaelAlg = Rijndael.Create(); using (CryptoStream cStream = new CryptoStream(outFStream, RijndaelAlg.CreateEncryptor(key, IV), CryptoStreamMode.Write)) { StreamWriter sWriter = new StreamWriter(cStream); fStream.CopyTo(cStream); } } } public void ExecuteEncrypted() { using (FileStream fStream = new FileStream(Environment.SpecialFolder.MyDocuments + "test.crp", FileMode.Open, FileAccess.Read, FileShare.Read), outFStream = new FileStream(Environment.SpecialFolder.MyDocuments + "crpTemp.exe", FileMode.Create)) { Rijndael RijndaelAlg = Rijndael.Create(); using (CryptoStream cStream = new CryptoStream(fStream, RijndaelAlg.CreateDecryptor(key, IV), CryptoStreamMode.Read)) { //Here you have a choice. If you want it to only ever exist decrypted in memory then you have to use the method in // the linked answer. //If you want to run it from a file than it's easy and you save the file and run it, this is simple. cStream.CopyTo(outFStream); } } Process.Start(Environment.SpecialFolder.MyDocuments + "crpTemp.exe"); } }
