+# MilvusDemo
+
+一个使用 C#（.NET 9）与 `Milvus.Client` 的极简示例项目，演示：
+- 初始化集合（存在则删除并重建）
+- 创建向量索引与加载集合
+- 批量插入随机向量
+- 执行向量相似度搜索
+- 通过内置测试流程验证调用链
+
+### 模块划分
+- **App（入口层）**：`Program.cs`
+  - 提供交互式入口：输入 1=实际连接 Milvus 执行；输入 2=运行内置测试（无需 Milvus 实例）。
+- **Core/Service（业务层）**：`MilvusService.cs`
+  - 封装与 Milvus 的连接、集合初始化、索引创建/加载、数据插入与搜索。
+- **Test Harness（测试层）**：`TestRunner.cs`、`MilvusServiceTests.cs`
+  - `TestRunner` 负责编排测试流程；`MilvusServiceTests` 提供无外部依赖的模拟测试（验证调用链与参数）。
+
+### 环境要求
+- .NET SDK 9.0+
+- 仅当选择“实际运行（选项 1）”时需要：可访问的 Milvus Server（默认 `localhost:19530`）。
+
+### 快速开始
+1. 构建
+   ```powershell
+   dotnet build
+   ```
+2. 运行（测试模式，无需 Milvus）
+   - PowerShell：
+     ```powershell
+     echo 2 | dotnet run
+     ```
+   - Bash：
+     ```bash
+     echo 2 | dotnet run
+     ```
+3. 运行（实际连接 Milvus）
+   - 确保本地或可达的 Milvus 实例运行在 `localhost:19530`。
+   - 程序启动后输入 `1`。
+
+### 启动 Milvus（可选）
+若需在本机快速启动 Milvus，可参考官方快速开始，或使用 Docker（示例）：
+
+```bash
+# 仅供参考，建议按官方文档选择合适的版本与持久化配置
+docker pull milvusdb/milvus:latest
+docker run -d --name milvus-standalone -p 19530:19530 milvusdb/milvus:latest
+```
+
+文档：`https://milvus.io/docs`（查看“Get Started / Install”）。
+
+### 主要参数（实际运行模式）
+- 主机与端口：`localhost:19530`
+- 集合名：`csharp_demo_collection`
+- 向量维度：`8`
+
+> 提示：若需修改连接地址或集合名，请在代码中相应位置调整（例如在连接初始化与集合定义处）。
+
+### 文件说明
+- `Program.cs`：控制台入口与菜单；调用服务或测试。
+- `MilvusService.cs`：核心服务，封装 Milvus 客户端操作。
+- `MilvusServiceTests.cs`：简单的模拟测试实现（不依赖 Milvus）。
+- `TestRunner.cs`：运行测试流程的编排类。
+- `MilvusDemo.csproj`：项目与依赖定义（包含 `Milvus.Client`）。
+
+### 常见问题（FAQ）
+- 无法连接到 Milvus：请确认 Milvus 是否已启动并监听 `19530` 端口，以及本机/容器网络连通性。
+- 还原/编译失败：请确认已安装 .NET 9 SDK，并允许联网下载 NuGet 依赖；必要时执行 `dotnet restore` 后再构建。
+- 端口占用：如 `19530` 已被占用，请修改容器映射或程序连接端口并保持一致。
