.NET：读/写二进制字符串

编辑：不要回答；我自己找到了解决方案。

我有一些代码可以执行此操作：

using (var stream = new FileStream(args[1], FileMode.Create))
{
 using (var writer = new BinaryWriter(stream))
 {
  writer.Write(ip.Iso3166CountryCode);
  ...
 }
}

Iso3166CountryCode 是一个带有两个字符（“US”）的字符串。

当我尝试从文件中读取“US”时：

// line is a byte[] from the file with the first 1024 bytes
UnicodeEncoding.Default.GetString(line.Take(2).ToArray());

我没有得到“US”，而是得到了一些奇怪的 ASCII 字符。如何从此二进制文件中读取两个国家/地区代码字符？

编辑：没关系。我将 writer.Write(ip.Iso3166CountryCode) 更改为 writer.Write(UnicodeEncoding.Default.GetBytes(ip.Iso3166CountryCode)) 并且它有效。 EM>

EDIT: Don't answer; I've found the solution on my own.

I have some code that does this:

using (var stream = new FileStream(args[1], FileMode.Create))
{
 using (var writer = new BinaryWriter(stream))
 {
  writer.Write(ip.Iso3166CountryCode);
  ...
 }
}

Iso3166CountryCode is a string with two characters ("US").

When I try to read "US" from the file:

// line is a byte[] from the file with the first 1024 bytes
UnicodeEncoding.Default.GetString(line.Take(2).ToArray());

I don't get "US" back, I get some odd ASCII characters back. How do I read the two country-code characters from this binary file?

EDIT: NEVER MIND. I changed writer.Write(ip.Iso3166CountryCode) to writer.Write(UnicodeEncoding.Default.GetBytes(ip.Iso3166CountryCode)) and it works.
