LeetCode 插件配置#

选择默认语言：设置 > 扩展 > LeetCode > Default Language 选择 csharp
重点：打开 settings.json 添加配置

1
"leetcode.filePath": {
2
    "default": {
3
        "folder": "src/${id}-${PascalCaseName}",
4
        "filename": "Solution-.${ext}"
5
    }
6
},

配置完成后，点击题目介绍页面的 Code Now 就会按设置生成脚本。更方便的尝试与管理多种解题思路。

LeetCode-File-List

调试与构建配置#

项目根目录新建 LeetCode.csproj ：

1
<!-- LeetCode.csproj -->
2
<Project Sdk="Microsoft.NET.Sdk">
3
    <PropertyGroup>
4
        <OutputType>Exe</OutputType>
5
        <TargetFramework>net8.0</TargetFramework>
6
        <ImplicitUsings>enable</ImplicitUsings>
7
        <Nullable>enable</Nullable>
8
    </PropertyGroup>
9
</Project>

新建 .vscode/launch.json ：

1
{
2
    "version": "0.2.0",
3
    "configurations": [
4
        {
5
            "name": ".NET Core Launch (console)",
6
            "type": "coreclr",
7
            "request": "launch",
8
            "preLaunchTask": "build",
9
            "program": "${workspaceFolder}/bin/Debug/net8.0/LeetCode.dll",
10
            "args": [],
11
            "cwd": "${workspaceFolder}",
12
            "console": "internalConsole",
13
            "stopAtEntry": false,
14
            "logging": {
15
                "moduleLoad": false
16
            }
17
        },
18
        {
19
            "name": ".NET Core Attach",
20
            "type": "coreclr",
21
            "request": "attach"
22
        }
23
    ]
24
}

新建 .vscode/tasks.json ：

1
{
2
    "version": "2.0.0",
3
    "tasks": [
4
        {
5
            "label": "build",
6
            "command": "dotnet",
7
            "type": "process",
8
            "args": [
9
                "build",
10
                "${workspaceFolder}/LeetCode.csproj",
11
                "-p:StartupObject=LeetCode.P${input:problem}.S${input:solution}.Program",
12
                "/property:GenerateFullPaths=true",
13
                "/consoleloggerparameters:NoSummary;ForceNoAlign"
14
            ],
15
            "problemMatcher": "$msCompile"
16
        }
17
    ],
18
    "inputs": [
19
        {
20
            "id": "problem",
21
            "description": "Please enter the problem ID.",
22
            "default": "",
23
            "type": "promptString"
24
        },
25
        {
26
            "id": "solution",
27
            "description": "Please enter the solution number.",
28
            "default": "1",
29
            "type": "promptString"
30
        }
31
    ]
32
}

调试前的脚本准备#

命名空间#

为需要本地测试的解题脚本分配一个唯一的命名空间。

Solution-Namespace

程序入口#

一个题解对应一个程序入口。

Solution-Main

调试#

按下 F5 开始调试，顶部会弹出提示框，填入要调试的题号与题解号。结果输出在底部的调试控制台。

使用代码片段快捷补全#

新建 .vscode/csharp.code-snippets 复制粘贴下面内容：

1
{
2
    "SolutionNamespace": {
3
      "scope": "csharp",
4
      "prefix": "ns",
5
      "body": [
6
        "namespace LeetCode.P$1.S$2;"
7
      ],
8
      "description": "Solution Namespace"
9
    },
10
    "TestProgram": {
11
      "scope": "csharp",
12
      "prefix": "tp",
13
      "body": [
14
        "public static class Program",
15
        "{",
16
        "    public static void Main()",
17
        "    {",
18
        "        var solution = new Solution();",
19
        "        ",
20
        "        solution$1",
21
        "    }",
22
        "}"
23
      ],
24
      "description": "Test Program"
25
    },
26
    "DisableWarning": {
27
      "scope": "csharp",

      "body": [
30
        "#pragma warning disable"
