查看器/编辑器、代码编辑器和二维码生成等功能。项目基于 .NET 9.0 开发，旨在为 Blazor 应用提供高质量、易用的 UI 组件。\n\n## 📦 安装\n\n通过 NuGet 包管理器安装:\n\n```bash\ndotnet add package Biwen.Blazor.Components --version 1.0.0-beta4\n```\n\n或在包管理器控制台中执行:\n\n```\nInstall-Package Biwen.Blazor.Components -Version 1.0.0-beta4\n```\n\n## 🚀 组件\n\n### 语法高亮组件 CodeHighlighter\n\n语法高亮使用 `Prism.js`，支持 `C#`、`CSS`、`HTML`、`JavaScript`、`JSON`、`Markdown`、`TypeScript` 等多种编程语言。\n\n#### 功能特点\n- 支持多种编程语言\n- 可配置行号显示\n\n#### 示例代码\n\n```razor\n\u003cCodeHighlighter LineNumbers=\"true\"\u003e\n\u003cpre\u003e\n    \u003ccode class=\"language-csharp\"\u003e\n    private int currentCount = 0;\n    private void IncrementCount()\n    {\n        currentCount++;\n    }\n    \u003c/code\u003e\n\u003c/pre\u003e\n\u003c/CodeHighlighter\u003e\n```\n\n\n### Markdown显示组件 MarkdownViewer\n\n提供 Markdown 文件显示功能，可以从文件路径或直接内容渲染 Markdown。\n\n#### 功能特点\n- 支持从文件路径或直接内容渲染 Markdown\n- 代码块语法高亮功能\n- 可配置代码块行号显示\n\n#### 使用步骤\n\n##### 1. 注册 HttpClient 服务\n```csharp\n// 请注意如果是 Blazor WebAssembly 项目，需要自行解决跨域问题\nbuilder.Services.AddScoped\u003cHttpClient\u003e();\n```\n\n##### 2. 使用 MarkdownViewer 组件\n\n```razor\n\u003c!-- 从文件路径加载 Markdown --\u003e\n\u003cMarkdownViewer FromAsset=\"/master/README.md\" CodeHighlight=\"true\" CodeHighlightRowNumber=\"true\" /\u003e\n\n\u003c!-- 或者直接传递 Markdown 内容 --\u003e\n\u003cMarkdownViewer Content=\"* 也可以这样传递 Markdown 内容\" /\u003e\n```\n\n### Markdown编辑器 MarkdownEditor\n\n提供功能丰富的 Markdown 编辑体验，支持图片上传等高级功能。\n\n#### 功能特点\n- 所见即所得的 Markdown 编辑\n- 支持图片上传\n- 支持通过引用获取编辑器内容\n\n#### 属性说明\n- `Content` - Markdown 初始内容\n- `UploadImage` - 是否支持图片上传（默认为 false）\n- `UploadImagePath` - 图片上传接口地址\n- `ImageMaxSize` - 图片大小限制（单位：KB，默认 2048 = 2MB）\n- `ImageAccept` - 支持的图片格式（默认 `image/png,image/jpeg`）\n\n#### 示例代码\n\n```razor\n\u003cMarkdownEditor @ref=\"editor\" Content=\"@md\" UploadImage=\"true\" UploadImagePath=\"/upload\"\u003e\u003c/MarkdownEditor\u003e\n\n@code {\n    private string md = \"## Hello World\";\n    private MarkdownEditor editor = null!;\n    \n    private async Task GetContent()\n    {\n        var content = editor.Content;\n        await Task.CompletedTask;\n    }\n}\n```\n#### 图片上传配置\n\n当 `UploadImage=true` 时需要提供上传地址，以下是一个服务端上传接口示例：\n\n```csharp\napp.MapPost(\"/upload\", ([FromServices] IWebHostEnvironment env, IFormFileCollection files) =\u003e\n{\n    // 注意：此示例禁用了防伪标记，生产环境需要处理权限和安全问题\n    // 此示例一次只支持上传一个文件\n    \n    if (files.Count == 0)\n    {\n        return Results.Json(new { error = \"400\" });\n    }\n\n    var wwwroot = env.WebRootPath;\n    var file = files[0];\n    var ext = Path.GetExtension(file.FileName);\n    string fileName = $\"{Guid.NewGuid()}{ext}\";\n    // 如果需要按日期存储目录，请自行实现\n    var filePath = Path.Combine(wwwroot, \"uploads\", fileName);\n    \n    // 确保目录存在\n    Directory.CreateDirectory(Path.GetDirectoryName(filePath)!);\n    \n    using var stream = new FileStream(filePath, FileMode.CreateNew);\n    file.CopyTo(stream);\n\n    return Results.Json(new\n    {\n        data = new\n        {\n            // 注意：需要使用绝对地址，如 http://localhost:5000/uploads/xxx.png\n            filePath = $\"/uploads/{fileName}\"\n        }\n    });\n}).DisableAntiforgery();\n\n```\n\n### 代码编辑器 CodeEditor (Monaco Editor)\n\n基于 Monaco Editor（VS Code 的编辑器）的代码编辑组件，提供丰富的代码编辑功能。\n\n#### 功能特点\n- 支持多种编程语言\n- 智能代码高亮\n- 行号显示控制\n- 内容变更事件\n- 多种自定义样式\n\n#### 属性说明\n- `Language` - 编辑器语言，支持 `csharp`、`css`、`html`、`javascript`、`json`、`markdown`、`typescript` 等\n- `Value` - 编辑器初始内容\n- `Style` - 编辑器 CSS 样式\n- `ShowLineNumbers` - 是否显示行号（默认 true）\n-

ShowLineNumbers=\"true\"\n    @onchange=\"HandleCodeChange\"\u003e\n\u003c/CodeEditor\u003e\n\n@code {\n    private string initialCode = \"using System;\\n\\nnamespace Demo\\n{\\n    public class Program\\n    {\\n        public static void Main()\\n        {\\n            Console.WriteLine(\\\"Hello World!\\\");\\n        }\\n    }\\n}\";\n    private CodeEditor codeEditor = null!;\n\n    private void HandleCodeChange(string newValue)\n    {\n        // 处理代码变更\n        Console.WriteLine($\"Code changed: {newValue}\");\n    }\n}\n```\n\n### 二维码组件 QRCode\n\n用于生成可自定义的二维码。\n\n#### 功能特点\n-
