4.Python读取共享内存中的二维数组其中array就是读取出来的浮点二维数组。1.创建一个浮点二维数组，并转换为字节数组。3.将字节数组保存到共享内存中。2.浮点二维数组转字节数组。

2.Python读取内存 filename分别为TireGlueing和FoamStick。1.C#写入内存的方法，FileName是内存共享的名字 t是内存size。我这里做一个简单的示例。

网络通讯中需要使用中文字符通讯。 if (client == null) { client = SocketFactory.CreateClient<TcpClient>(IP, Port); client.TimeOut = 300000; client.Encoding = Encoding.GetEncoding(936); //936表示GB2312.

Dictionary<string, string> Content = new Dictionary<string, string>(); Content.Add("bulletinContent", "this is bulletinContent"); Content.Add("topToDay", "this is topToDay");//Dictionary转json string Contentjson = JsonConvert.SerializeObje.

1.首先写一个linq扩展类using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace aaa.utils{ static class LinqExt { public class DGroupBy<T> : IGrouping<object[], T> { privat.

感觉这种方法获取摄像头列表名称，比较方便using System.Management; private static void GetUSBDevices() { var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE (PNPClass = 'Image' OR PNPClass = 'Camera')"); .

<Image x:Name="iCamera" Margin="10,25,0,0" Width="200" Height="160" Source="Assets/Images/redo.png" VerticalAlignment="Top"> <Image.Clip> <RectangleGeomet...

1.通过nuget安装OpenCvSharp4 ，下面四个都要安装否则会出现错误！2.运行摄像头代码windows_loaded中的代码 Thread threadA = new Thread(run_cap); threadA.Start();摄像头图像代码 void run_cap() { Mat src = new Mat(); FrameSource ..

private void tbPassword_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Enter) { btnLogin.RaiseEvent(new RoutedEventArgs(Button.ClickEvent)); ; } }

1.由于需要把主窗体的数据，发送到UserControl中。考虑到Android中有EventBus。觉得自己写个方法实现。下面是中间件using System;using System.Collections.Generic;using System.Diagnostics;using System.Text;namespace InfusionBagSmartLaber.Communication{ public class EventBus { s

项目中要使用tcp通讯，接收事件想通过委托实现，发现Action非常好用下面是网络通讯部分代码using BeetleX;using BeetleX.Clients;using InfusionBagSmartLabeler;using InfusionBagSmartLabeler.utils;using System;using System.Collections.Generic;using System.Diagnostics;using System.Text;using

1.xaml按钮设置Command="{Binding ButtonIncrease}" 这里是命令绑定 <StackPanel Grid.Column="1" Orientation="Horizontal"> <Button Content="+" Command="{Binding ButtonIncrease}" Height="20" Margin="5,-2,0,0" ..

private void Window_Loaded(object sender, RoutedEventArgs e) { Process[] pro = Process.GetProcesses(); int n = pro.Where(p => p.ProcessName.Equals("InfusionBagSmartLaber")).Count(); if (n > 1..

1.nuget添加cefsharp声明 xmlns:wpf="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"在xaml文件中使用 <wpf:ChromiumWebBrowser Grid.Row="2" x:Name="webBrowser" Address="www.baidu.com"> </wpf:ChromiumWebBrowser>..

今天编译一个,net core 2.0的代码，部署后出现502.5错误。安装.net core sdk 2.2以及dotnet-hosting-2.2.8-win.在cmd以管理员身份执行安装AspNetCoreModule托管模块后执行1.net stop was /y2.net start w3svc刷新页面显示正常...

select --ROWID ,(select count(*) from VisionTemplate b where a.id >= b.id) as row_number ,* from VisionTemplate as a order by id;

想通过id删除list的内容.通过linq删除比较方便Lists.Remove(Lists.Where(p => p.ID == CurID).FirstOrDefault());

DataGridTemplateColumn col1 = new DataGridTemplateColumn(); col1.Header = "操作"; FrameworkElementFactory factory1 = new FrameworkElementFactory(typeof(Button)); //b1.Mode = BindingMode.TwoWay; Bi...

1 从NuGet包中添加2.github源码地址https://github.com/praeclarum/sqlite-netC# 操作代码 private void Button_Click_3(object sender, RoutedEventArgs e) { string databasePath = System.AppDomain.CurrentDomain.BaseDirectory + "db/mydb.db...

首次使用Beetlex ，做个记录using BeetleX;using BeetleX.Clients;using System;using System.Collections.Generic;using System.Configuration;using System.Diagnostics;using System.Linq;using System.Net;using System.Text;using System.Threading;using System.Th.

1.修改构造函数using Microsoft.EntityFrameworkCore;using Microsoft.Extensions.Configuration;using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;namespace WEBAPI.EF{ public class LabelContext:DbContext {...

1.在appsettings.json中加入"urls":"http://*.5000"2.在program.cs中加入var configuration = new ConfigurationBuilder().SetBasePath(Environment.CurrentDirectory) .AddJsonFile("appsettings.json") ...
