在VScode中使用C#开发

VScode仅限于微型项目或测试 写项目还是老老实实用Visual Studio吧！

环境

• VSC本体
• .NET Core SDK，可以访问dot.net下载
• VSC扩展：C#、Code Runner

操作步骤

• 建立一个空文件夹
• 打开终端（TERMINAL） 输入 dotnet new console 会自动生成Hello World文件
• 按F5即可运行
• 还需要做一点修改。左边点开.vscode文件夹：

  launch.json："console": "integratedTerminal", "internalConsoleOptions": "neverOpen";  .NET Core Attach可以删掉。
  tasks.json：给build加上"group": { "kind": "build", "isDefault": true },（打group就>会自动提示）

  如使用runner 需要设置环境变量

  csc是编译C#的程序。安装VS，把 安装路径下\Microsoft VisualStudio
  \2019\Community\MSBuild\Current\Bin\Roslyn\加到Path里。

常见问题

'scriptcs' is not recognized as an internal or external command, operable program or batch file.

You need both the script runner extension and to install scripts

Installation and information guide is here: http://scriptcs.net/

1. Install chocolatey
2. Run cinst scriptcs to install the latest version.

error CS7021: You cannot declare namespace in script code

It’s complaining about the namespace, so remove it from the Program.cs

The name 'Console' does not exist in the current context

using System;

Feature 'default literal' is not available in C# 8.0. Please use language version 9.0 or greater.

Adding

<LangVersion>latest</LangVersion>

under the <PropertyGroup> tags

in your pubxml(**.csproj) file seems to fix it.

int是带符号的，表示范围是：-2147483648到2147483648，即-2^31到2^31次方。

uint则是不带符号的，表示范围是：2^32即0到4294967295。
