将SID字符串格式转换为字节数组 [英] Convert SID string format to bytes array

问题描述

我想将SID字符串格式转换为字节数组表示形式，然后将其提供给C#中LookupAccountSid()方法的第二个参数.但是我没有发现可以执行此操作的任何内置函数.例如:

I want to convert SID string format to bytes array representation which in turn will be supplied to LookupAccountSid() method's second argument in C#. But I don't find any particular in built function which can do this. For example:

SID = S-1-5-32-544

SID = S-1-5-32-544

可以转换为:

(SID:1,2,0,0,0,0,0,5,32,0,0,0,32,2,0,0)

(SID: 1,2,0,0,0,0,0,5,32,0,0,0,32,2,0,0)

我在一些帖子中看到了.但是如何? 有没有简单的方法可以做到这一点?基本上，我想要NT Authority\NetworkService的字节数组表示形式，即SID = S-1-5-20.预先感谢您的帮助.

I saw it in some posts. but how? Is there a easy way to achieve this? Basically I want the byte array representation of the NT Authority\NetworkService which is SID = S-1-5-20. Thanks in advance for your help.

推荐答案

您应使用 SecurityIdentifier 对象:

You should use SecurityIdentifier object from System.Security.Principal namespace:

var sid = new SecurityIdentifier("S-1-5-32-544");
byte[] bytes = new byte[sid.BinaryLength];
sid.GetBinaryForm(bytes, 0);

，如果您希望将其作为文本，则可以:

and if you want it as a text, you can then:

string strsid = string.Format("(SID: {0})", string.Join(",", bytes ));

产生的确切结果:

(SID:1,2,0,0,0,0,0,5,32,0,0,0,32,2,0,0)

(SID: 1,2,0,0,0,0,0,5,32,0,0,0,32,2,0,0)

此外，如果您希望SID为NT Authority\NetworkService，则可以将第一行替换为:

Moreover, if you want SID of NT Authority\NetworkService, you can replace first line with:

var sid = new SecurityIdentifier(WellKnownSidType.NetworkServiceSid, null);
