这是在AssemblyA中

ClassB b = new ClassB();
Console.WriteLine(b.MultiplyTheSumByFactor(2, 3, 4));
Console.ReadKey();

public int Multiply(int left, int right)

return left * right;

int sum = …我使用以下属性来装饰我的BaseController类.
public class OutputCompressAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
string encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
if (string.IsNullOrEmpty(encodingsAccepted))
return;
encodingsAccepted = encodingsAccepted.ToLowerInvariant();
HttpResponseBase response = filterContext.HttpContext.Response;
if (encodingsAccepted.Contains("gzip"))
{
response.AppendHeader("Content-encoding", "gzip");
response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
}
else if (encodingsAccepted.Contains("deflate"))
{
response.AppendHeader("Content-encoding", "deflate");
response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
}
}
}
问题是,即使这对视图和每个操作结果都很好,该属性也不适用于/Content项目文件夹中的内容.我想知道我是如何做到这一点,以便文件Content夹中的文件使用控制器,或以某种方式绑定或钩住允许我将这些过滤器附加到响应头的东西.
我有一个完全有效的CSS样式表,它可以工作,并且可以识别查询,但是当我使用SquishIt缩小(并连接)样式表时,媒体查询似乎停止工作,我无法弄清楚原因.

section#layout-content …以下必须是Angular.js开发人员在某些时候进行故障排除时最常见的错误.
错误:$申请已在进行中
有时,$scope.$apply完全不需要呼叫,删除它可以解决问题.有些时候,它可能是需要的,因此开发人员采用以下模式.
if(!$scope.$$phase) {
$scope.$apply();
}
我的问题是,为什么Angular只是在调用循环或调用循环时只检查$scope.$$phase和return不执行任何操作,而不是抱怨并抛出一个如此难以追踪的错误.$digest$scope.$apply
Angular是否只是$$phase在任何方法的入口点检查自己,这些方法触发$digest并保存消费者不必经历麻烦？
$scope.$apply除了不需要的手表射击之外,是否有任何影响可能会导致错误的呼叫,这些检查$$phase会阻止？
为什么不$$phase检查默认值,而不是奇怪？
我从升级角度1.2.1来1.2.6当页面加载,所以我不知道从哪里它源自该异常被抛出.因此,问题是,为什么我们甚至不得不追查这种模糊不清的错误而不知道我们的代码在哪里寻找它？
我使用Dragula在我的应用程序上实现了拖放,但是我需要设置它以便我可以将我的元素放到多个div中.
我尝试使用一个类来实现它,但它只是激活我的第一个div.
HTML:
<div role="presentation" class="table table-striped">
<div class="files" id="upload-file"></div>
</div>
<div class="col-md-4">
<div class="drag-container">Test 1</div>
<div class="drag-container">Test 2</div>
<div class="drag-container">Test 3</div>
</div>
JS调用Dragula:
dragula([document.querySelector('#upload-file'), document.querySelector('.drag-container')]);
如何将te项目丢弃到多个div？
namespace MyNamespace
{
public struct MyStruct
{
public string MyString;
public int MyInt;
public bool MyBool;
}
public class MyClass
{
private List<MyStruct> MyPrivateVariable;
public List<MyStruct> MyVariable
{
get
{
if (MyPrivateVariable == null)
{
MyPrivateVariable = new List<MyStruct>();
MyPrivateVariable.Add(new MyStruct());
MyPrivateVariable.Add(new MyStruct());
}
return MyPrivateVariable;
}
}
public void MyLoop()
{
foreach (MyStruct ms in MyVariable)
{
// Doesn't compile, but it works if you execute it through the Immediate window, or in Quickwatch
ms.MyBool = false;
// Compiles, …最后使用有什么区别
void ReadFile(int index)
{
// To run this code, substitute a valid path from your local machine
string path = @"c:\users\public\test.txt";
System.IO.StreamReader file = new System.IO.StreamReader(path);
char[] buffer = new char[10];
try
{
file.ReadBlock(buffer, index, buffer.Length);
}
catch (System.IO.IOException e)
{
Console.WriteLine("Error reading from {0}.
Message = {1}", path, e.Message);
}
finally
{
if (file != null)
{
file.Close();
}
}
// Do something with buffer...
}
而不是使用它？
void ReadFile(int index)
{
// To run this code, substitute a … string c = tmpArr[0].Aggregate(string.Empty, (current, m) => current + (m.Name + " "));
StringBuilder sb = new StringBuilder();
foreach (Mobile m in tmpArr[0])
sb.Append(m.Name + " ");
sb.ToString();
哪两个更快？聚合肯定是更干净,但它是快速还是与做的一样
foreach(Mobile m in tmpArr[0])
c += m.Name + " ";
我真正想做的事情就是这样string.Join(",",tmpArr[0]),但我不想让它连接他们的ToString值,只是他们的名字,我怎么能做到最好？
我没有使用的问题string.Join是我实际上必须做这样的事情:
string separator = "";
StringBuilder sb = new StringBuilder();
foreach (Mobile m in tmpArr[0])
{
separator = ", ";
sb.Append(separator + m.Name);
}
public int CalcBrackets(int teamCount)
{
int positions = 1;
while (positions < teamCount)
positions *= 2;
return positions;
}
我想要的最小数字是2的幂,大于或等于teamCount.这真的是最好的方法吗？肯定看起来很可怕:(
我在WCF服务上有以下方法:
/// <summary>
/// Receives the result of a request processing
/// </summary>
/// <param name="results">The resulting statuses for the processed account requests</param>
/// <returns>Whether the response was successfully handled</returns>
public bool SendRequestProcessingResult(IEnumerable<RequestProcessingResult> results)
{
foreach (var result in results)
{
// update entity
}
}
有没有办法一次更新所有实体？我应该只添加每个更新SaveChanges吗？在EF 4.1中进行这种"大规模"更新的最佳方法是什么？
