我正在尝试创建一组 FTP Web 请求以下载一组文件。

在单个线程中正确执行此操作，但现在正在尝试使用多个线程，但出现超时异常。我想我错过了一些非常简单但似乎无法解决的问题

这是代码：

internal static void DownloadLogFiles(IEnumerable<string> ftpFileNames, string localLogsFolder)
{
    BotFinder.DeleteAllFilesFromDirectory(localLogsFolder);

    var ftpWebRequests = new Collection<FtpWebRequest>();

    // Create web request for each log filename
    foreach (var ftpWebRequest in ftpFileNames.Select(filename => (FtpWebRequest) WebRequest.Create(filename)))
    {
        ftpWebRequest.Credentials = new NetworkCredential(BotFinderSettings.FtpUserId, BotFinderSettings.FtpPassword);
        ftpWebRequest.KeepAlive = false;
        ftpWebRequest.UseBinary = true;
        ftpWebRequest.CachePolicy = NoCachePolicy;
        ftpWebRequest.Method = WebRequestMethods.Ftp.DownloadFile;
        ftpWebRequests.Add(ftpWebRequest);
    }

    var threadDoneEvents = new ManualResetEvent[ftpWebRequests.Count];

    for (var x = 0; x < ftpWebRequests.Count; x++)
    {
        var ftpWebRequest = ftpWebRequests[x];
        threadDoneEvents[x] = new ManualResetEvent(false);

我为我的应用程序创建了一个自定义配置部分.由于某种原因,Visual Studio 2010没有拾取和我的自定义属性.对于所有"添加"键,我收到与此类似的警告:

Could not find schema information for the element 'urlFilterSection'

配置文件:

<configSections>
    <section name="urlFilterSection" type="BotFinderApp.Models.UrlFilterSection, BotFinder" />
</configSections>

<urlFilterSection>
    <urlFilterCollection>
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />

我正在处理LocalDateTime对象，并希望将它们存储为Long纳秒精度。

我尝试过在Instant表示之间进行转换，但到目前为止失败了。

例如：

localDateTime.toInstant(ZoneOffset.UTC).getNano

仅返回纳秒部分localDateTime- 有没有办法返回完整的纳秒值？

类似于toEpochSecond纳秒，但不是以秒为单位？

我创建了一个依赖于 SLF4J 的包，因此我使用 Logback 来实现 OSGI。这一切都捆绑起来并安装正常，但是当我开始捆绑时，出现以下异常：

org.osgi.framework.BundleException：无法解析 com.felix.test [20]（R 20.0）：缺少要求 [com.felix.test [20]（R 20.0）] osgi.wiring.package；(osgi.wiring.package=groovy.lang) 未解决的需求：[[com.felix.test [20](R 20.0)] osgi.wiring.package; (osgi.wiring.package=groovy.lang)]

我可以看到我的清单文件中groovy.lang列出了Import-Package，我很确定问题是 Logback 已被嵌入，但它的引用都没有。

我用来创建捆绑包，这是配置：

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>2.5.4</version>
    <extensions>true</extensions>

我试图通过pg_dump在 Docker 容器中运行kubectl并将输出保存到我​​的本地机器。

这是我到目前为止所拥有的：

kubectl exec -it MY_POD_NAME -- pg_dump -h DB_HOST -U USER_NAME SCHEMA_NAME > backup.sql

然而，这目前只是挂起。我相当肯定这是由于--忽略了>

kubectl exec -it MY_POD_NAME -- pg_dump -h DB_HOST -U USER_NAME SCHEMA_NAME 按预期输出到控制台。

简单的问题,但我无法在MSDN上的任何地方找到答案...

寻找ASP.NET将用于的默认值:

MailMessage.BodyEncoding 和 MailMessage.SubjectEncoding

如果你没有在代码中设置它们？

谢谢

我将字典绑定到下拉列表.

比如说我在字典中有以下项目:

{"Test1", 123}, {"Test2", 321} 

我希望下拉文本采用以下格式:

Test1 - Count: 123
Test2 - Count: 321

我没有运气,沿着以下道路前进:

MyDropDown.DataTextFormatString = string.Format("{0} - Count: {1}", Key, Value);

谢谢 :)

使用C#绑定到MVC3中的视图模型.

设置文本框的初始值有困难,尝试这样做而无需创建模板等

任何想法或我是否必须走创建自定义模板的道路？

蒂姆,谢谢

我正在尝试使用 Filebeat 将我的 K8s pod 日志发送到 Elasticsearch。

我在这里在线遵循指南：https : //www.elastic.co/guide/en/beats/filebeat/6.0/running-on-kubernetes.html

一切都按预期工作，但是我想从系统 pod 中过滤掉事件。我更新的配置看起来像：

apiVersion: v1
kind: ConfigMap
metadata:
  name: filebeat-prospectors
  namespace: kube-system
  labels:
    k8s-app: filebeat
    kubernetes.io/cluster-service: "true"
data:
  kubernetes.yml: |-
    - type: log
      paths:
        - /var/lib/docker/containers/*/*.log
  multiline.pattern: '^\s'
  multiline.match: after
  json.message_key: log
  json.keys_under_root: true
  processors:
    - add_kubernetes_metadata:
        in_cluster: true
        namespace: ${POD_NAMESPACE}
    - drop_event.when.regexp:
        or:
          kubernetes.pod.name: "weave-net.*"

          kubernetes.pod.name: "nginx-ingress-controller.*"
          kubernetes.pod.name: "filebeat.*"

我试图忽视weave-net，external-dns，ingress-controller并filebeat通过事件：

- drop_event.when.regexp:
    or:
      kubernetes.pod.name: "weave-net.*"
      kubernetes.pod.name: "external-dns.*"

我有一个非常简单的文本文件解析应用程序,它搜索电子邮件地址,如果找到则添加到列表中.

目前列表中有重复的电子邮件地址,我正在寻找一种快速修改列表的方法,只包含不同的值 - 而不是逐个迭代它们:)

这是代码 -

var emailLines = new List<string>();
using (var stream = new StreamReader(@"C:\textFileName.txt"))
{
    while (!stream.EndOfStream)
    {
        var currentLine = stream.ReadLine();

        if (!string.IsNullOrEmpty(currentLine) && currentLine.StartsWith("Email: "))
        {
            emailLines.Add(currentLine);
        }
    }
}
