I'm building my project with the "Microsoft Minimal Rules" code analysis set and it gives me CA2000 on this method: private Timer InitializeTimer(double intervalInSeconds) { Timer timer = null; try { timer = new Timer { Interval = intervalInSeconds * 1000, Enabled = true }; timer.Elapsed += timer_Elapsed; timer.Start(); } catch {
我正在用“微软最小规则”代码分析集来构建我的项目，它给了我这种方法的CA2000： private Timer InitializeTimer(double intervalInSeconds) { Timer timer = null; try { timer = new Timer { Interval = intervalInSeconds * 1000, Enabled = true }; timer.Elapsed += timer_Elapsed; timer.Start(); } catch { if (timer != null) { timer.
PARI/GP is opensource, is written in C and it supports some basic linear algebra over finite field. No warranties for specific suitability from me, of course - I'm not related to the development.
PARI / GP是开源的，用C编写，支持有限域上的一些基本线性代数。 当然，我不担保具体的适用性 - 我与发展无关。
This is the code that creates the performance counter: var ftpPerfCounter = new PerformanceCounter("FTP Service", "Current Connections", "_Total"); This is where the exception happens: int cnt = (int)Math.Round(ftpPerfCounter.NextValue()); Here's the Exception message: "Error Message: The Counter layout for the Category specified is invalid, a counter of the type: AverageCount64, A
这是创建性能计数器的代码： var ftpPerfCounter = new PerformanceCounter("FTP Service", "Current Connections", "_Total"); 这是发生异常的地方： int cnt = (int)Math.Round(ftpPerfCounter.NextValue()); 这是Exception消息： “错误消息：指定类别的计数器布局无效，类型：AverageCount64，AverageTimer32，CounterMultiTimer，CounterMultiTimerInverse，CounterMultiTimer100Ns，CounterMultiTimer100NsInverse，R
During debugging our application in linux enviroment we can observe that some events - POLLHUP|POLLIN occur only on linux. Our application uses unix sockets. When we do: ret = poll(xpoll->pfd, xpoll->pfd_count, xpoll_timeout); strace shows: poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}, {fd=6, events=POLLIN|POLLPRI|POLLERR|POLLHUP}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP}],
在Linux环境下调试我们的应用程序期间，我们可以观察到一些事件 - POLLHUP|POLLIN仅在Linux上发生。 我们的应用程序使用unix套接字。 当我们这样做时： ret = poll(xpoll->pfd, xpoll->pfd_count, xpoll_timeout); strace显示： poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}, {fd=6, events=POLLIN|POLLPRI|POLLERR|POLLHUP}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 3, 16) = 1 ([{fd=7, revents
我怎么能完全禁用WinForm的WebBrowser的JavaScript？ You can't. Client apps cannot disable JavaScript in the browser. 有了这个，你可以禁用JavaScript的警告webBrowser.ScriptErrorsSuppressed = true;

I get a ProtoException ("Possible recursion detected (offset: 4 level(s)): o EOW") when serializing a tree structure like so: var tree = new PrefixTree(); tree.Add("racket".ToCharArray()); tree.Add("rambo".ToCharArray()); using (var stream = File.Open("test.prefix", FileMode.Create)) { Serializer.Serialize(stream, tree); } The tree i
当序列化一个树结构时，我得到一个ProtoException （“检测到可能的递归（偏移：4个级别）：EOW”）： var tree = new PrefixTree(); tree.Add("racket".ToCharArray()); tree.Add("rambo".ToCharArray()); using (var stream = File.Open("test.prefix", FileMode.Create)) { Serializer.Serialize(stream, tree); } 树的实现： [ProtoContract] public class PrefixTree
I'm learning WebAPI (and REST in general) by converting an existing WCF service to WebAPI. In the process, I'm becoming confused as to the best way to handle the non-CRUD operations. Here is my Service Contract: [ServiceContract] public interface IProxyHelper { [OperationContract] List<ProxyInfo> GetUsersCurrentUserCanActAsProxyFor(int positionId, int appId); [Operat
我通过将现有的WCF服务转换为WebAPI来学习WebAPI（通常是REST）。 在这个过程中，我对处理非CRUD操作的最佳方式感到困惑。 这是我的服务合同： [ServiceContract] public interface IProxyHelper { [OperationContract] List<ProxyInfo> GetUsersCurrentUserCanActAsProxyFor(int positionId, int appId); [OperationContract] void DeleteProxy(int id); [OperationContract] List<ProxyI
I'm working on a C# application that contains a lot of DataGridViews which are empty. The user has to fill them with copy/pasted data from excel. What I do is the following: int i = 0; string s = Clipboard.GetText(); // Separate lines string[] lines = Regex.Split(s, "rn"); foreach (string line in lines) { // Separate each cell string[] cells = line.Split('t'); foreach (string
我正在研究一个包含很多DataGridViews的C＃应用程序，这些DataGridViews是空的。 用户必须从excel中复制/粘贴数据。 我做的是以下几点： int i = 0; string s = Clipboard.GetText(); // Separate lines string[] lines = Regex.Split(s, "rn"); foreach (string line in lines) { // Separate each cell string[] cells = line.Split('t'); foreach (string cell in cells) { // If we selected a
Running the same Stored Procedure from C# .Net application over a network gets progressively slower with each subsequent execution. It appears to take twice the amount of time as the previous execution (up to a max value; read on). The execution time becomes progressively slower until 1 of 2 scenarios happens, at which point the first execution of the SPROC is "fast" again. If an Sq
通过网络从C＃.Net应用程序运行相同的存储过程随着每次后续执行逐渐变慢。 它看起来要比前一次执行时间缩短两倍 （达到最大值;请继续阅读）。 执行时间逐渐变慢，直到发生两种情况中的一种，此时SPROC的第一次执行又是“快速”。 如果SqlConnection在所有测试期间打开并保持打开状态，则SPROC会逐渐变慢，直到运行其他 SPROC 或查询为止。 如果在每次执行时打开并关闭SqlConnection ，则SPROC将逐渐变慢，直到至少8分钟过去
I have a user control which has a DateTimePicker overlaid with the single line text box(Tb) covering the text part of DateTimePicker. The textbox Tb ( green ) is anchored (LTRB). The problem comes when the usercontrol is resized. The overlaid datetimepicker shows up behind the text Tb. Currently the user control is 242(W) x 20(H) . Problems shows up when control is resized below 100 (Wi
我有一个用户控件，它有一个DateTimePicker与单行文本框（Tb）重叠， 覆盖DateTimePicker的文本部分。 文本框Tb（ 绿色 ）被锚定（LTRB）。 调整usercontrol的大小时会出现问题。 叠加的datetimepicker出现在文本Tb后面。 目前用户控制是242（W）x 20（H）。 当控制调整到100（宽度）以下时，问题就会显现出来。 我尝试将CustomFormat设置为“”的文本留空，但用户控件支持许多datetimepicker功能，因此这不是一个选项
