# LingYanEverythingSharp

### 介绍
用C#仿照Everything的搜索引擎，不同于其他调用Everything包的扩展，本搜索引擎完全摆脱Everything库，独立运行。

### 软件架构
本搜索引擎满足netstandard2.0;netstandard2.1两大标准，意味着可同时在.NetFramework与.NetCore当中运行。

### 安装方式

```
//Nuget包管理器添加源

名称：灵燕开源合集
源(s):> https://nuget.lingyanspace.com/v3/index.json

//看到LingYanEverythingSharp包安装即可

```

### 使用说明
无需搭理其他类，只需要关注EngineManager

#### 第一步：全局初始化搜索引擎

```
EngineManager.EngineInit();

注意返回值:Tuple<string, Stopwatch>;

成功时第一个参数返回success，第二个参数为本次操作所用时间统计
```

#### 第二步：在你的业务系统当中采用linq与lamda来写表达书目录树

```
//查询单个

EngineManager.GetFirstOrDefault(
 Expression<Func<FileAndDirectoryEntry, bool>> predicate = null,
 Expression<Func<FileAndDirectoryEntry, FileAndDirectoryEntry>> selector = null,
 Func<IQueryable<FileAndDirectoryEntry>, IOrderedQueryable<FileAndDirectoryEntry>> orderBy = null);

//查询所有

EngineManager.GetAll(
 Expression<Func<FileAndDirectoryEntry, bool>> predicate = null,
 Expression<Func<FileAndDirectoryEntry, FileAndDirectoryEntry>> selector = null,
 Func<IQueryable<FileAndDirectoryEntry>, IOrderedQueryable<FileAndDirectoryEntry>> orderBy = null);

//分页查询所有

EngineManager.GetPageList(
 Expression<Func<FileAndDirectoryEntry, bool>> predicate = null,
 Expression<Func<FileAndDirectoryEntry, FileAndDirectoryEntry>> selector = null,
 Func<IQueryable<FileAndDirectoryEntry>, IOrderedQueryable<FileAndDirectoryEntry>> orderBy = null,
 int pageIndex = 1,
 int pageSize = 20);

//查询总数

EngineManager.GetCount(
 Expression<Func<FileAndDirectoryEntry, bool>> predicate = null);
```
