我试图从一个SSL证书读取信息(在这种情况下,我已经保存的StackOverflow的通过浏览器的副本),但由于某种原因,我建立并从Linux泊坞容器内运行的那一刻,它不能输出任何东西.
在Windows上,输出是我所期望的:

我有以下代码.
public static void GuessTheType()
{
dynamic hasValue = true;
dynamic value = "true";
var whatami1 = hasValue ? (string)value : null;
var whatami2 = hasValue ? bool.Parse(value) : true;
var whatami3 = hasValue ? (bool)bool.Parse(value) : true;
}
编译器推断的类型whatami1是string.
编译器推断的类型whatami2是dynamic.
编译器推断的类型whatami3是bool.
为什么第二种类型不是bool？
我是json的新人.我想要不同用户的信息,并将它们添加到c#(.net development)中的dataGridView 或dataTable或dataSet中.信息样本是(json有效):
{
"JrPwbApfIHbQhCUmVIoiVJcPYv93": {
"address": "Jessore",
"name": "Dev"
},
"iBRZAyn8TQTOgKTcByGOvJjL9ZB3": {
"address": "Bogra",
"name": "Kumar Saikat"
}
}
我希望他们这样:
User1 | 杰索尔| 开发
User2 | Bogra | Kumar Saikat
如果我可以列出所有这些列表,它甚至会有所帮助.
我相信我能够对它们进行反序列化(根本不确定)
var model = JsonConvert.DeserializeObject<user>(json);
用户是一个类.
public class Item
{
public string name;
public string address;
}
从这个问题的答案.在本教程中,如果知道属性,我可以获取值.但在我的情况下,我的属性将是未知的,(字符串"User1","User2"将是随机的,因为我将从数据库中获取它们).任何有关此事的帮助和亮点将不胜感激.先感谢您.
我正在尝试设置对 RabbitMQ 队列的订阅并将其传递给自定义事件处理程序。所以我有一个名为的类RabbitMQClient，其中包含以下方法：
public void Subscribe(string queueName, EventHandler<BasicDeliverEventArgs> receivedHandler)
{
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())
{
channel.QueueDeclare(
queue: queueName,
durable: false,
exclusive: false,
autoDelete: false,
arguments: null
);
var consumer = new EventingBasicConsumer(channel);
consumer.Received += receivedHandler;
channel.BasicConsume(
queue: queueName,
autoAck: false,
consumer: consumer
);
}
}
}
我正在使用依赖注入，所以我有一个RabbitMQClient（单例）接口。
在我的消费类中，我有这个方法，我想充当 EventHandler
public void Consumer_Received(object sender, BasicDeliverEventArgs e)
{
var message = e.Body.FromByteArray<ProgressQueueMessage>();
}
我正在尝试像这样订阅队列：
rabbitMQClient.Subscribe(Consts.RabbitMQ.ProgressQueue, Consumer_Received);
我可以看到队列开始获取消息，但该Consumer_Received方法没有触发。
我在这里缺少什么？
我的任务很简单：我在 C# 字符串中有一个 CSV 文件，用分号分隔。我需要为每个空单元格添加空格。A;B;;;;C;应该成为A;B; ; ; ;C;. 现在，我使用了两次替换方法：
csv = csv.Replace(";;", "; ;").Replace(";;", "; ;");
这是必要的，因为在第一遍中，它将替换任何出现的 ;; 之间有一个空格，但没有回溯，因此不会再次检查替换序列的第二个分号。因此，我最终会得到 a A;B; ;; ;C;，这不是我想要的。
有没有更优雅、更清晰、更少冗余的方法来解决这个任务？
有开始、执行和取消，但是如果我想检测我是否按住了游戏手柄上的按钮，该怎么办。所以基本上，我如何使用新的输入系统将其重写为游戏手柄。
private void Jump()
{
if (isTouchingGround == true && Input.GetKeyDown(KeyCode.Space))
{
isJumping = true;
jumpTimeCounter = jumpTime;
myRigidbody2D.velocity = new Vector2(myRigidbody2D.velocity.x, 1 * jumpSpeed);
}
if (Input.GetKey(KeyCode.Space) && isJumping == true)
{
if (jumpTimeCounter > 0)
{
myRigidbody2D.velocity = new Vector2(myRigidbody2D.velocity.x, 1 * jumpSpeed);
jumpTimeCounter -= Time.deltaTime;
}
else
{
isJumping = false;
}
}
if (Input.GetKeyUp(KeyCode.Space))
{
isJumping = false;
}
}
是否可以在同一属性上使用公共 init 访问器和私有 setter？
目前我收到错误CS1007 “已定义属性访问器”。
public record Stuff
{
public int MyProperty { get; init; private set; } // Error
public void SetMyProperty(int value) => MyProperty = value;
}
var stuff = new Stuff
{
MyProperty = 3, // Using the init accessor
};
stuff.SetMyProperty(4); // Using the private setter (indirectly)
我最好的猜测是使用私有成员变量，该变量的属性get和init访问器（不是自动实现的）和 setter 成员函数。可以更轻松地完成吗？
我正在对从 TryGet 获得的值执行两次更新，我想知道哪个更好？
选项 1：只锁定价值？
if (HubMemory.AppUsers.TryGetValue(ConID, out OnlineInfo onlineinfo))
{
lock (onlineinfo)
{
onlineinfo.SessionRequestId = 0;
onlineinfo.AudioSessionRequestId = 0;
onlineinfo.VideoSessionRequestId = 0;
}
}
选项 2：锁定整个字典？
if (HubMemory.AppUsers.TryGetValue(ConID, out OnlineInfo onlineinfo))
{
lock (HubMemory.AppUsers)
{
onlineinfo.SessionRequestId = 0;
onlineinfo.AudioSessionRequestId = 0;
onlineinfo.VideoSessionRequestId = 0;
}
}
