我有一个方法HandlerThread.一个值在内部发生变化Thread,我想将它返回给test()方法.有没有办法做到这一点？

public void test()
{   
    Thread uiThread = new HandlerThread("UIHandler"){
        public synchronized void run(){
            int value; 
            value = 2; //To be returned to test()
        }
    };
    uiThread.start();
}

负载和压力测试有什么区别？

我正在尝试整理我的flexbox布局,以便与最新版本的IE/Firefox/Safari兼容,而且我遇到了Firefox/Safari的问题.

拟议布局:

-----------------
     header
-----------------
    |
    |
    |
nav |  section
    |
    |
    |
    |

在Firefox和Safari <section>下面nav

CSS:

body {
  width:50%;
  height:100%;
  display: -ms-flexbox;
  -ms-box-orient: horizontal;

  display: -webkit-flex;
  display: -moz-flex;
  display: -ms-flexbox;
  display: flexbox;

  -webkit-flex-flow: row wrap;
  -moz-flex-flow: row wrap;
  -ms-flex-flow: row wrap;
  flex-flow: row wrap;
}

header {
    padding-top:100px;
    -webkit-flex: 1 100%;
    -moz-flex: 1 100%;
    -ms-flex: 1 100%;
    flex: 1 100%;
}

nav {
    -webkit-flex: 1;
    -moz-flex: 1;
    -ms-flex: 1;
    flex: 1;
    width:10%;
    height:100%;
}

我的应用程序中有一个方法,它检索我的DCIM/Camera文件夹中最后保存的图像并将其复制到SD卡上的另一个位置.我刚刚在另一部手机上测试了它,发现默认保存为DCIM/100MEDIA.我怎么能得到这条路？

我最后编写了一些代码,这些代码循环遍历DCIM文件夹中的所有文件夹,并检索lastModified()文件夹的路径.

我有一个带有2个可选参数的方法.

public IList<Computer> GetComputers(Brand? brand = null, int? ramSizeInGB = null)
{
    return new IList<Computer>();
}

我现在正尝试在其他地方使用此方法,我不想指定Brand参数,只是int但我使用此代码时遇到错误:

_order.GetComputers(ram);

我收到的错误:

Error   1   The best overloaded method match for 'ComputerWarehouse.Order.GetComputers(ComputerWarehouse.Brand?, int?)' has some invalid arguments  C:\Users\avmin!\Documents\InnerWorkings Content\630dd6cf-c1a2-430a-ae2d-2bfd995881e7\content\T0062A2-CS\task\ComputerWarehouse\ComputerStore.cs 108 59  ComputerWarehouse

尝试使用moq和unity对我的应用程序进行单元测试,我收到的错误是我的服务是一个接口,无法解决:

我刚刚在VS 2010中创建了一个新的基本MVC 4应用程序.我只是单击了播放按钮来测试它在Web浏览器中出现并且我得到以下页面:

我想我需要改变我的虚拟路径,但我不知道是什么.

编辑:无法在图片中看到它说的正确:

Server Error in '/' Application.

我正在尝试IEnumerable<string>从linq查询返回一个我收到错误:无法转换IEnumerable<AnonymousType>为IEnumerable<string>

我不知道如何解决这个问题.

private IEnumerable<string> GetAllMembers(Type type)
        {    

            var query =
                (from member in type.GetMembers()
                 select new
                 {
                     Member = member.GetType() + " " + member.ToString()

                 }
                );

            return query;
        }

我似乎找不到任何与此相关的文档，是不是很简单：

//option 1
${something},${something1}
//option 2
123,234,762

任何帮助将非常感激。

我试图将一个元素推到这个数组的末尾,我得到一个我不明白的错误.

main.rb的:

require 'shop.rb'
so = Shop.new()
so.get(2)
so.get(1)

shop.rb

class Shop

    def new()
       @products = []
    end


    def get(product)
       @products.push(product)
    end
end

错误:

NoMethodError: undefined method `push' for nil:NilClass

我正在使用ASP.NET授权在登录前拒绝用户访问我的网站,但这也阻止了Register.cshtml页面.如何整理授权以允许此页面通过？

  </system.web>

  <location path="Content">

我不明白为什么代码A是正确的,代码B是不正确的:

代码A.

IEnumerable<decimal> loanQuery = 
from amount in loanAmounts
where amount % 2 == 0
orderby amount 
select ascending amount //this line

代码B(不正确)

IEnumerable<decimal> loanQuery = 
from amount in loanAmounts
where amount % 2 == 0
select amount 
orderby ascending amount

由于很多人都回答不正确,我现在发布了正确的代码:

IEnumerable<decimal> loanQuery = 
from amount in loanAmounts
where amount % 2 == 0
orderby amount ascending
select amount
