堆栈溢出Userpic生成（标识） [英] Stack Overflow Userpic generation (Identicons)

问题描述

我正在C＃ASP.NEt中创建一个网站，并希望使用类似于Stack Overflow的功能，
每次新用户在StackOverflow.com上注册时，都会为其分配一个默认用户图片，直到拥有一个gravatar，现在每张图片都不同于上一张，因此可以确定它是生成的，我想知道如何在C＃中完成。

i an creating a website in C# ASP.NEt and want to use a feature similar to Stack Overflow, Every time a new user registers on the StackOverflow.com he is assigned a default user picture until he has a gravatar, Now every picture is different from the previous one, so it is sure it is generated, i want to know how can this be done in C#.

注意：（我不认为这是一个元问题，所以请不要将其移到那里。）

Note: (I don't think it is a meta question so please don't move it there)

推荐答案

它称为身份。它们是通过某种哈希生成的图像，通常是在用户名或电子邮件上生成的。

It's called Identicions. They are images generated by some kind of hash, usually on a username or email.

在Codeplex上有一个不错的开源库，用于生成Identicons。更多信息此处。

There is a nice, open source library, on Codeplex for generating Identicons. More info here.

编辑：您实际上可以使用gravatar来生成Identicons 。构造这样的URL：

You can actually use gravatar to generate Identicons. Construct a URL like this:

http://www.gravatar.com/avatar/HASH_HERE?s=128&d=identicon&r=PG
