请演示三元运算符如何使用常规if/else块.例:

Boolean isValueBig = value > 100 ? true : false;

完全重复: 如何使用三元运算符？

有没有办法在C#代码中发送电子邮件而不必知道服务器上的SMTP服务器配置等,或者设置了这些东西？

我有一个空的DIV元素,我在其中使用函数createElement("img")附加图像并使用appendChild附加它们.所以现在我已经拥有了充满图像的DIV元素.

两个关键字Shadows和Overrides有什么意义？他们做了什么以及哪个环境是一个或另一个更好？

使用BeautifulSoup 3.1.0.1和Python 2.5.2,并尝试用法语解析网页.但是,一旦我调用findAll,我就会收到以下错误:

UnicodeEncodeError:'ascii'编解码器无法对位置1146中的字符u'\ xe9'进行编码:序数不在范围内(128)

以下是我目前正在运行的代码:

import urllib2
from BeautifulSoup import BeautifulSoup
page = urllib2.urlopen("http://fr.encarta.msn.com/encyclopedia_761561798/Paris.html")
soup = BeautifulSoup(page, fromEncoding="latin1")
r = soup.findAll("table")
print r

有人知道为什么吗？

谢谢!

更新:如果被请求,下面是完整的回溯

Traceback (most recent call last):
  File "[...]\test.py", line 6, in <module>
    print r
UnicodeEncodeError: 'ascii' codec can't encode characters in position 1146-1147: ordinal not in range(128)

GetType() returns null when the type exists in an unreferenced assembly. For example, when the following is called "localType" is always null (even when using the full namespace name of the class):

Type localType = Type.GetType("NamespaceX.ProjectX.ClassX");

I don't see any reason why Type.GetType shouldn't be able to retrieve a type from an unreferenced assembly, so

How can the type of an unreferenced assembly be retrieved?

I am comparing two almost identical folders which include hidden .svn folders which should be ignored and I want to continually quickly compare the folders as some files are patched to compared the difference without checking the unchanged matching files again.

edit: Because there are so many options I'm interested in a solution that clearly exploits the knowledge from the previous compare because any other solution is not really feasable when doing repeated comparisons.

I have a java application I need to pass some info to a C++ program. It has been suggested that I use some simple socket programming to do this. Is this the best way? If not what are the alternatives? If so, how should I go about learning about socket programming?

按照这个问题的说明,我运行了一些代码来从文件中提取图标并将它们显示在ListView设置为详细信息模式中.我希望图标显示为16 x 16,但是当我将ImageList大小设置为时,出现的图标看起来非常奇怪(不确定如何描述它 - 请参阅附带的屏幕截图).

我已经尝试将尺寸改为32 x 32并且它们很好,但肯定必须有一种方法来获得高质量16 x 16图标一定不存在？
