标题已经说明了一切:
- 我这样从一个tar.gz归档文件中读取:
- 将文件分成字节数组
- 将这些字节转换为Base64字符串
- 将该Base64字符串转换回字节数组
- 将这些字节写回新的tar.gz文件
我可以确认两个文件的大小相同(下面的方法返回true),但我无法再提取复制版本。
我是否遗漏了什么?
Boolean MyMethod(){
using (StreamReader sr = new StreamReader("C:\...\file.tar.gz")) {
String AsString = sr.ReadToEnd();
byte[] AsBytes = new byte[AsString.Length];
Buffer.BlockCopy(AsString.ToCharArray(), 0, AsBytes, 0, AsBytes.Length);
String AsBase64String = Convert.ToBase64String(AsBytes);
byte[] tempBytes = Convert.FromBase64String(AsBase64String);
File.WriteAllBytes(@"C:\...\file_copy.tar.gz", tempBytes);
}
FileInfo orig = new FileInfo("C:\...\file.tar.gz");
FileInfo copy = new FileInfo("C:\...\file_copy.tar.gz");
// Confirm that both original and copy file have the same number of bytes
return (orig.Length) == (copy.Length);
}
编辑:感谢@T.S.,工作示例要简单得多:
Boolean MyMethod(){
byte[] AsBytes = File.ReadAllBytes(@"C:\...\file.tar.gz");
String AsBase64String = Convert.ToBase64String(AsBytes);
byte[] tempBytes = Convert.FromBase64String(AsBase64String);
File.WriteAllBytes(@"C:\...\file_copy.tar.gz", tempBytes);
FileInfo orig = new FileInfo(@"C:\...\file.tar.gz");
FileInfo copy = new FileInfo(@"C:\...\file_copy.tar.gz");
// Confirm that both original and copy file have the same number of bytes
return (orig.Length) == (copy.Length);
}
感谢!
