## 7. 场景创建流程

### 从文件名解析

```csharp
// Services/ScenarioService.cs
public async Task<TestScenario> GetOrCreateFromFileNameAsync(string fileName)
{
    // 1. 解析文件名
    var parts = ParseFileName(fileName);
    // 格式: TX面板-TX硬件-TX软件-RX类型-测试目的-年月日-测试次数.log
    
    // 2. 获取或创建各维度
    var txPanel = await txPanelService.GetOrCreateAsync(parts.TxPanel);
    var txHardware = await txHardwareService.GetOrCreateAsync(parts.TxHardware);
    var txSoftware = await txSoftwareService.GetOrCreateAsync(parts.TxSoftware);
    var rxType = await rxTypeService.GetOrCreateAsync(parts.RxType);
    
    // 3. 检查场景是否已存在
    var existing = await context.TestScenarios
        .FirstOrDefaultAsync(s => 
            s.TxPanelId == txPanel.Id &&
            s.TxHardwareId == txHardware.Id &&
            s.TxSoftwareId == txSoftware.Id &&
            s.RxTypeId == rxType.Id &&
            s.TestPurpose == parts.TestPurpose &&
            s.TestDate == parts.TestDate &&
            s.TestSequence == parts.TestSequence);
    
    if (existing != null) return existing;
    
    // 4. 创建新场景
    var scenario = new TestScenario
    {
        TxPanelId = txPanel.Id,
        TxHardwareId = txHardware.Id,
        TxSoftwareId = txSoftware.Id,
        RxTypeId = rxType.Id,
        TestPurpose = parts.TestPurpose,
        TestDate = parts.TestDate,
        TestSequence = parts.TestSequence
    };
    
    context.TestScenarios.Add(scenario);
    await context.SaveChangesAsync();
    
    return scenario;
}
```

### 手动创建

```csharp
public async Task<TestScenario> CreateAsync(CreateScenarioRequest request)
{
    // 1. 验证维度是否存在
    var txPanel = await context.TxPanels.FindAsync(request.TxPanelId)
        ?? throw new NotFoundException("TX面板不存在");
    var txHardware = await context.TxHardwares.FindAsync(request.TxHardwareId)
        ?? throw new NotFoundException("TX硬件版本不存在");
    // ... 其他维度验证
    
    // 2. 创建场景
    var scenario = new TestScenario
    {
        TxPanelId = request.TxPanelId,
        TxHardwareId = request.TxHardwareId,
        TxSoftwareId = request.TxSoftwareId,
        RxTypeId = request.RxTypeId,
        TestPurpose = request.TestPurpose,
        TestDate = request.TestDate,
        TestSequence = request.TestSequence
    };
    
    context.TestScenarios.Add(scenario);
    await context.SaveChangesAsync();
    
    return scenario;
}
```
