我正在使用 C# 开发一个网络应用程序，通过网络发送大量纯数字。我发现了 IPAddress.HostToNetworkOrder 和 IPAddress.NetworkToHostOrder 方法，它们非常有用，但它们给我留下了几个问题：
-
我知道我需要编码和解码整数，无符号整数怎么样？我想是的，所以目前我正在通过将指向无符号 int 的指针转换为指向 int 的指针，然后进行网络转换来实现这一点int（因为没有采用无符号整数的方法重载）
公共静态 UInt64 HostToNetworkOrder(UInt64 i)
{
Int64 a = *((Int64*)&i);
a = IPAddress.HostToNetworkOrder(a);
返回 *((UInt64*)&a);
}
公共静态 UInt64 NetworkToHostOrder（UInt64 a）
{
Int64 i = *((Int64*)&a);
i = IPAddress.HostToNetworkOrder(i);
返回 *((UInt64*)&i);
}
2。 浮点数（单精度和双精度）怎么样？。我认为不，但是如果我确实需要，我应该对无符号整数执行类似的方法并将单个指针转换为 int 指针并像这样进行转换吗？
编辑:: 乔恩的答案没有回答后半部分的问题（它也没有真正回答第一部分！），我希望有人回答第二部分
I'm working on a networking application in C#, sending a lot of plain numbers across the network. I discovered the IPAddress.HostToNetworkOrder and IPAddress.NetworkToHostOrder methods, which are very useful, but they left me with a few questions:
-
I know I need to encode and decode integers, what about unsigned ones? I think yes, so at the moment I'm doing it by casting a pointer to the unsigned int into a pointer to an int, and then doing a network conversion for the int (since there is no method overload that takes unsigned ints)
public static UInt64 HostToNetworkOrder(UInt64 i)
{
Int64 a = *((Int64*)&i);
a = IPAddress.HostToNetworkOrder(a);
return *((UInt64*)&a);
}
public static UInt64 NetworkToHostOrder(UInt64 a)
{
Int64 i = *((Int64*)&a);
i = IPAddress.HostToNetworkOrder(i);
return *((UInt64*)&i);
}
2. What about floating point numbers (single and double). I think no, however If I do need to should I do a similar method to the unsigned ints and cast a single pointer into a int pointer and convert like so?
EDIT:: Jons answer doesn't answer the second half of the question (it doesn't really answer the first either!), I would appreciate someone answering part 2

我怀疑您会发现在 EndianBinaryReader 和
EndianBinaryWriter会更容易="nofollow noreferrer">MiscUtil - 然后你可以自己决定字节序。或者，对于单个值，您可以使用EndianBitConverter。I suspect you'd find it easier to use my
EndianBinaryReaderandEndianBinaryWriterin MiscUtil - then you can decide the endianness yourself. Alternatively, for individual values, you can useEndianBitConverter.您最好阅读几篇 RFC 文档，了解不同的 TCP/IP 协议（应用程序级别，例如 HTTP/FTP/SNMP 等）有何不同。
一般来说，这是一个特定于协议的问题（都是您的问题），因为您的数据包必须以协议定义的格式封装整数或浮点数。
对于 SNMP，这是一种将整数/浮点数更改为几个字节然后再更改回来的转换。使用 ASN.1。

You'd better read several RFC documents to see how different TCP/IP protocols (application level, for example, HTTP/FTP/SNMP and so on).
This is generally speaking, a protocol specific question (both your questions), as your packet must encapsulate the integers or floating point number in a protocol defined format.
For SNMP, this is a conversion that changing an integer/float number to a few bytes and changing it back. ASN.1 is used.
