dllImport的入口点问题 通过Dependencies查询Dll对应方法的EntryPoint 然后在dllimport的attribute中显式申明EntryPoint [DllImport("demo.dll", SetLastError = true,EntryPoint ="??0DemoManager@EcgParser@Gfeit@@AEAA@XZ")] public static extern IntPtr DemoManager(); 导入类方法的问题 最好的方式还是使用C++构造wrapper，然后通过windowsApi的方式调用Pinvoke 参考链接 swig nuget swig C++/C# interoperability Working with C++ Interface Classes from C# Call function in unmanaged DLL from C# and pass custom data types [Marshal] SWIG and C# Example for SWIG to wrap C++ library in .Net 6

创建 一般使用 使用 httputil.NewSingleHostReverseProxy 即可 返回Response 当我们想实现获取通过ReverseProxy的请求结果时，可以使用自定义的 responsewriter 来实现。参考定义 func (p *ReverseProxy) ServeHTTP(rw http.ResponseWriter, req *http.Request) { .... } type ResponseWriter interface { // Header returns the header map that will be sent by // WriteHeader. The Header map also is the mechanism with which // Handlers can set HTTP trailers. // // Changing the header map after a call to WriteHeader (or // Write) has no effect unless the modified headers are // trailers....

环境准备 nuget包 Microsoft.Extensions.Configuration Microsoft.Extensions.Configuration.Binder Microsoft.Extensions.Configuration.Json (当需要从Json文件添加记录时，安装此nuget包) Microsoft.Extensions.Configuration.EnvironmentVariables (当需要从环境变量添加记录时，安装此nuget包) C#开发环境 visual studio 2019 + visual Code 示例代码 // See https://aka.ms/new-console-template for more information using Microsoft.Extensions.Configuration; using Microsoft.Extensions.Configuration.Json; Console.WriteLine("Hello, World!"); ConfigurationBuilder configurationBuilder = new ConfigurationBuilder(); IConfiguration c = configurationBuilder.AddJsonFile("appsettings.json").AddEnvironmentVariables().Build(); var k = c.GetRequiredSection("Settings").Get<Settings>().KeyOne; var n = 1; public class NestedSettings { public string Message { get; set; } = null!; } public class Settings { public int KeyOne { get; set; } public bool KeyTwo { get; set; } public NestedSettings KeyThree { get; set; } = null!...

Windows XP时代 Xp时代提供的是通过注册表来自定义shell 设置所有用户的shell 注册表键HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell 设置当前用户的shell注册表键 HKEY_Current_User\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell 注册表键值类型 REG_SZ 值修改为你要自定义为shell的程序的完整路径。 在windows10下使用该技巧可能会出现黑屏的现象，参考stackoverflow的回答 Simply replacing the “explorer.exe” (HKLM\SOFTWARE\Microsoft\Window NT\Winlogon\Shell) with a custom app location provided a black screen. A much simpler way, and it works great, was to create a BATCH script to call the custom app through elevated powershell… powershell -nologo -noprofile -executionpolicy bypass -command "start-process -verb 'runas' -filepath <full path of custom app executable>" By replacing “explorer.exe” with this batch script I was able to successfully create a kiosk style lockdown under Windows 10 PRO with a non-UWP app....

问题描述 使用go正常编译了Linux下的程序，放到服务器上报错 ./app: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by ./app) 解决 Google了下，发现相同的Issue,于是通过go env检查本机golang运行环境，发现CGO默认启用而且程序也不涉及CGO相关的东西，于是设置CGO参数为关闭。然后编译程序 CGO_ENABLED="0" go build -v 重新上传，运行OK.

安装步骤 查询系统版本 执行命令lsb_release -a返回下面的内容 LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: AlibabaCloud Description: Alibaba Cloud Linux release 3 (Soaring Falcon) Release: 3 Codename: SoaringFalcon 添加yum源 创建repo文件etc/yum.repos.d/mongodb.repo并输入下面的内容，这里安装的mongodb版本为6.0,其他版本请参考官网（配置偶数版本，奇数版不适合生产使用）。 官网的配置文件如下： [mongodb-org-6.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc 使用这个配置文件是安装不了的，需要修改$releasever为相应的版本，Alibaba Cloud Linux 3修改为8 （设置一个releasever的环境变量也许也可以，没有验证。）即可。即下面的样子 [mongodb-org-6.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/8/mongodb-org/6.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc 使用命令 yum -y install mongodb-org 安装即可。另外阿里云也提供了国内的镜像源，上面的配置文件可以修改为下面的内容，也是等效的。 [mongodb-org-6.0] name=MongoDB Repository baseurl=http://mirrors.aliyun.com/mongodb/yum/redhat/8/mongodb-org/6.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc 参考链接 如何在Alibaba Cloud Linux 3上安装MongoDB 5.0
