entity-framework - 以代码优先方法映射 SQL View

Question

我有一个 SQL View :

WITH DirectReports (ID,ParentFolderID, ParentFolderName,FolderID,FolderName,OwnerOCID,OwnerArName,OwnerEnName,FolderType,LEVEL)
                            AS
                            (
SELECT        e.Id AS ID,cast(cast(0 AS binary) AS uniqueidentifier) AS ParentFolderID, cast('MainFolder - ' + MainFolders.enName AS nvarchar(250)) AS ParentFolderName, 
                         e.Id AS FolderID, e.Name AS FolderName, WorkSpaces.Owner_Id AS OwnerOCID, OrgCharts.arName AS OwnerArName, OrgCharts.enName AS OwnerEnName, 
                         MainFolders.Type AS FolderType, 0 AS LEVEL
FROM            WorkSpaceFolders AS e INNER JOIN
                         MainFolders ON MainFolders.RootFolder_Id = e.Id INNER JOIN
                         WorkSpaces ON WorkSpaces.Id = MainFolders.WorkSpace_Id INNER JOIN
                         OrgCharts ON OrgCharts.Id = WorkSpaces.Owner_Id
WHERE        e.Root = 1 AND e.Parent_Id IS NULL
UNION ALL
SELECT        e.Id AS ID,e.Parent_Id AS ParentFolderID, d .FolderName AS ParentFolderName, e.Id AS FolderID, e.Name AS ChildFolderName, d .OwnerOCID, d .OwnerArName, 
                         d .OwnerEnName, d .FolderType, LEVEL + 1
FROM            WorkSpaceFolders AS e INNER JOIN
                         DirectReports AS d ON e.Parent_Id = d .FolderID)
    SELECT        *
     FROM            DirectReports

我正在使用代码优先迁移到我的数据库 - 如何将 View 映射到以下实体？

public class UserFolders
{
    public Guid ID { get; set; }
    public Guid ParentFolderID { get; set; }
    public string ParentFolderName { get; set; }
    public Guid FolderID { get; set; }
    public string FolderName { get; set; }
    public Guid OwnerOCID { get; set; }
    public string OwnerArName { get; set; }
    public string OwnerEnName { get; set; }
    public int FolderType { get; set; }
    public int LEVEL { get; set; }
}

View 可以映射为表。它应该是这样的:

public class UserFoldersMap : EntityTypeConfiguration<UserFolders>
{
    public UserFoldersMap()
    {
        this.ToTable("view_name");

        this.HasKey(t => t.Id);                        
    }
}

希望能帮到你...
