我在尝试将保存的列表从二进制文件读回列表时遇到问题。该文件已加密,没有加密我没有问题。
写法:
private void WriteEncodedFile(FileStream fileStream, MemoryStream memoryStream)
{
StreamReader sr = new StreamReader(memoryStream);
BinaryWriter bw = new BinaryWriter(fileStream);
memoryStream.Seek(0, SeekOrigin.Begin);
string data = sr.ReadToEnd();
var bytes = Encoding.UTF8.GetBytes(data);
for (int i = 0; i < bytes.Length; i++) bytes[i] ^= 0x5a;
bw.Write(Convert.ToBase64String(bytes));
bw.Close();
fileStream.Close();
}
阅读方法:
private void ReadEncodedFile(FileStream fileStream, MemoryStream memoryStream)
{
BinaryReader br = new BinaryReader(fileStream);
StreamWriter sw = new StreamWriter(memoryStream);
fileStream.Seek(0, SeekOrigin.Begin);
memoryStream.Seek(0, SeekOrigin.Begin);
string base64 = br.ReadString();
byte[] bytes = Convert.FromBase64String(base64);
for (int i = 0; i < bytes.Length; i++) bytes[i] ^= 0x5a;
string decodedData = Encoding.UTF8.GetString(bytes);
sw.Write(decodedData);
}
阅读内容时,我可以在“decodedData”中看到它。但是 StreamWriter 似乎没有将其写入 MemoryStream。
任何想法?
谢谢。
