本文介绍了如何在c＃中加密和解密xml的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我遇到问题可能会有些帮助。 i写这个代码 XDocument doc = XDocument.Load（任何xml文件的文件路径）; string readxml = doc.ToString（）; string swapnil = Encrypt（readxml）; XDocument doc1 = XDocument.Parse（swapnil）; string avi = Decrypt（swapnil）; 使用xdocument我加载一个xml文件 然后在readxml我正在读取xdocument作为字符串因为我有加密和解密的方法接受字符串。在swapnil字符串中的我已经加密了数据。但是我想再次将字符串转换为xdocument类型。但是当我转换得到这个错误时。 根级别的数据无效。第1行，第1位。 下面是加密和解密的方法 私人只读Rfc2898Derive Bytes _DeriveBytes; private readonly byte [] _InitVectorBytes; private readonly byte [] _KeyBytes; private const string InitVector =T = A4rAzu94ez -dra; private const int PasswordIterations = 1000; // 2; 私有const字符串SaltValue =d =？ustAF = UstenAr3B @ pRu8 = ner5sW&h59_Xe9P2za-eFr2fa&ePHE @ ras！a + uc @; public string Decrypt（string encryptedText） { byte [] encryptedTextBytes = Convert.FromBase64String（encryptedText）; string plainText; RijndaelManaged rijndaelManaged = new RijndaelManaged {Mode = CipherMode.CBC}; try { 使用（ICryptoTransform decryptor = rijndaelManaged.CreateDecryptor（_KeyBytes，_InitVectorBytes）） { using（MemoryStream memoryStream） = new MemoryStream（encryptedTextBytes）） { 使用（CryptoStream cryptoStream = new CryptoStream（memoryStream，decryptor，CryptoStreamMode.Read）） { // TODO：需要更多地研究这个问题。假设加密文本比普通文本长，但可能有更好的方法 byte [] plainTextBytes = encryptedTextBytes; / * new byte [encryptedTextBytes.Length]; * / int decryptedByteCount = cryptoStream.Read（plainTextBytes，0，plainTextBytes.Length）; plainText = Encoding.UTF8.GetString（plainTextBytes，0，decryptedByteCount）; } } } } catch（CryptographicException exception） { plainText = string.Empty; //假设错误是由无效的密码引起的 } 返回plainText; } 公共字符串加密（string plainText） { string encryptedText; byte [] plainTextBytes = Encoding.UTF8.GetBytes（plainText）; RijndaelManaged rijndaelManaged = new RijndaelManaged {Mode = CipherMode.CBC}; 使用（ICryptoTransform encryptor = rijndaelManaged.CreateEncryptor（_KeyBytes，_InitVectorBytes）） { using（MemoryStream memoryStream = new MemoryStream（）） { 使用（CryptoStream cryptoStream = new CryptoStream（memoryStream，encryptor，CryptoStreamMode.Write）） { cryptoStream.Write（plainTextBytes，0，plain TextBytes.Length）; cryptoStream.FlushFinalBlock（）; byte [] cipherTextBytes = memoryStream.ToArray（）; encryptedText = Convert.ToBase64String（cipherTextBytes）; } } } 返回encryptedText; } 使用此方法我想加密和解密。 请帮帮我。Hi, I stuck in the problem may be some can help.i write this code XDocument doc = XDocument.Load(Filepath of any xml file"); string readxml = doc.ToString(); string swapnil = Encrypt(readxml); XDocument doc1 = XDocument.Parse(swapnil); string avi = Decrypt(swapnil);using xdocument i load a xml filethen in readxml i am reading xdocument as string because i have methods for encrytion and decrytion that accept string.in swapnil string i have encrypted the data. but again i want to convert the string into xdocument type. but when i am converting getting this error.Data at the root level is invalid. Line 1, position 1.below is methods for encrytion and decryption private readonly Rfc2898DeriveBytes _DeriveBytes; private readonly byte[] _InitVectorBytes; private readonly byte[] _KeyBytes; private const string InitVector = "T=A4rAzu94ez-dra"; private const int PasswordIterations = 1000; //2; private const string SaltValue = "d=?ustAF=UstenAr3B@pRu8=ner5sW&h59_Xe9P2za-eFr2fa&ePHE@ras!a+uc@"; public string Decrypt(string encryptedText) { byte[] encryptedTextBytes = Convert.FromBase64String(encryptedText); string plainText; RijndaelManaged rijndaelManaged = new RijndaelManaged { Mode = CipherMode.CBC }; try { using (ICryptoTransform decryptor = rijndaelManaged.CreateDecryptor(_KeyBytes, _InitVectorBytes)) { using (MemoryStream memoryStream = new MemoryStream(encryptedTextBytes)) { using (CryptoStream cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read)) { //TODO: Need to look into this more. Assuming encrypted text is longer than plain but there is probably a better way byte[] plainTextBytes = encryptedTextBytes; /*new byte[encryptedTextBytes.Length];*/ int decryptedByteCount = cryptoStream.Read(plainTextBytes, 0, plainTextBytes.Length); plainText = Encoding.UTF8.GetString(plainTextBytes, 0, decryptedByteCount); } } } } catch (CryptographicException exception) { plainText = string.Empty; // Assume the error is caused by an invalid password } return plainText; } public string Encrypt(string plainText) { string encryptedText; byte[] plainTextBytes = Encoding.UTF8.GetBytes(plainText); RijndaelManaged rijndaelManaged = new RijndaelManaged { Mode = CipherMode.CBC }; using (ICryptoTransform encryptor = rijndaelManaged.CreateEncryptor(_KeyBytes, _InitVectorBytes)) { using (MemoryStream memoryStream = new MemoryStream()) { using (CryptoStream cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write)) { cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length); cryptoStream.FlushFinalBlock(); byte[] cipherTextBytes = memoryStream.ToArray(); encryptedText = Convert.ToBase64String(cipherTextBytes); } } } return encryptedText; }using this method i want to encrypt and decrypt.please help me.推荐答案XDocument doc1 = XDocument.Parse("this is nonsense");<root><element1>等... 你不能用任何字符串制作Xml。 这里有关于xml的教程 http://www.w3schools.com/xml/ [ ^ ] 希望有帮助etc...You cannot make Xml out of any string.Here is tutorial about xmlhttp://www.w3schools.com/xml/[^]hope it helps 这篇关于如何在c＃中加密和解密xml的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
