EntityLoadInfo(ValueBuffer, Func<ValueBuffer,Object>)
初始化 EntityLoadInfo 結構的新執行個體。
public EntityLoadInfo (Microsoft.EntityFrameworkCore.Storage.ValueBuffer valueBuffer, Func<Microsoft.EntityFrameworkCore.Storage.ValueBuffer,object> materializer);new Microsoft.EntityFrameworkCore.Query.EntityLoadInfo : Microsoft.EntityFrameworkCore.Storage.ValueBuffer * Func<Microsoft.EntityFrameworkCore.Storage.ValueBuffer, obj> -> Microsoft.EntityFrameworkCore.Query.EntityLoadInfoPublic Sub New (valueBuffer As ValueBuffer, materializer As Func(Of ValueBuffer, Object))參數
- valueBuffer
- ValueBuffer
代表此實體的資料列。
- materializer
- Func<ValueBuffer,Object>
將資料具體化為實體實例的方法。
適用於
EntityLoadInfo(MaterializationContext, Func<MaterializationContext,Object>, Dictionary<Type,Int32[]>)
初始化 EntityLoadInfo 結構的新執行個體。
