C＃，我是linq的新手。请看我遇到的问题。 [英] C#, I am new to linq. Please see the problem I have.
问题描述
检查名称是否正确，这意味着第一个字母必须是大写，其余字母必须是小写。在
中，name为null，为空或长度小于2个字符的情况返回false。不要考虑前导空格或尾随空格。
public static bool NameIsInProperCase（string name）
{
}
我尝试了什么：
i无法访问我在工作中尝试使用我的电脑，我正在下载c＃IDE，以便在周末再试一次。我是Linq的新手。
Check to see if the name, is in proper case, which means the first letter must be uppercase and the rest of the letters must be lower case. In
the cases where name is null, empty, or is less than 2 characters long, return false. Do not take into account leading or trailing spaces.
public static bool NameIsInProperCase(string name)
{
}
What I have tried:
i can not access the attempts i made in my pc at work, I am currently downloading c# IDE to try again over the weekend. I am new to Linq.
推荐答案
不要使用Linq - 当你想对一个序列的所有元素做同样的事情时这很好，但当你没有用时希望第一次对待不同。
相反，使用正则表达式：
Don't use Linq - it's good when you want to do the same thing to all elements of a sequence, but useless when you want the first treated differently.
Instead, use a regex:
^[A-Z][a-z]+
应该这样做。
请参阅我有问题。
你遇到的问题是家庭作业！
我们不做你的家庭作业。
HomeWork不会在乞求其他人做你的工作时测试你的技能，它会让你思考并帮助你的老师检查你对你所学课程的理解以及你所遇到的问题。应用它们。
你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。
你的任何失败都会帮助你了解什么有效，什么无效，被称为'试错'学习。
所以，试一试，重读课程并开始工作。如果您遇到特定问题，请显示您的代码并解释这个问题，我们可能会提供帮助。
作为程序员，您的工作是创建算法解决特定问题，你不能依赖别人永远为你做，所以有一段时间你必须学会如何。而且越快越好。
当你要求解决方案时，就像试图通过培训其他人来学习开车一样。
创建算法基本上是找到数学并做出必要的调整以适应你的实际问题。
发展的概念就像这个词所暗示的那样：系统地使用科学和满足特定目标或要求的技术知识。 BusinessDictionary.com [ ^ ]
这与有一个不一样快速谷歌并放弃，如果我找不到正确的代码。
The problem you have is Homework !
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
The idea of "development" is as the word suggests: "The systematic use of scientific and technical knowledge to meet specific objectives or requirements." BusinessDictionary.com[^]
That's not the same thing as "have a quick google and give up if I can't find exactly the right code".
