用存储过程填充ViewModel

Question

我Stored Procedure在Sql Server中创建了这个：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[usp_GetUsrsofRole] (@RoleId int)
AS
;WITH CTE_UsersInRole AS
(
    SELECT 
     U.Id AS [UserId], U.Name AS [UserName] , U.Family AS [UserFamily] , R.Id AS[RoleID],R.Name AS [RoleName]
    FROM AspNetUserRoles AU 
    INNER JOIN AspNetRoles R ON R.Id=AU.RoleId
    INNER JOIN AspNetUsers U ON U.ID=AU.UserId
)
SELECT
     C.RoleID,C.RoleName,C.UserFamily,C.UserId,C.UserName
FROM CTE_UsersInRole C
    WHERE C.RoleID=@RoleId
GO

这是我的视图模型：

public class UserInRoleVM
{
    public string UserName { get; set; }
    public string UserFamily { get; set; }
    public string RoleName { get; set; }
    public int RoleId { get; set; }
    public int UserId { get; set; }

}

现在我需要在asp Core中用以下代码填充视图模型：

public IEnumerable<UserInRoleVM> GetUserOfRole(int id)
{
    List<UserInRoleVM> users = new List<UserInRoleVM>();
    users = TableAsNoTracking.FromSql("EXEC usp_GetUsrsofRole @p0", id).ToList();
    return users;
}

但这给了我这个错误：

严重性代码说明项目文件行抑制状态错误CS0029无法将类型'System.Collections.Generic.List'隐式转换为'System.Collections.Generic.List'FisziShimi.Services E：\ MyProject \ Farshid \ Backend \ FisziShimi \ FisziShimi.Services \ Services \ UserRoleService.cs 26有效

我怎么解决这个问题？

更新：

 public DbSet<TEntity> Entities { get; }
 public virtual IQueryable<TEntity> Table => Entities;
 public virtual IQueryable<TEntity> TableAsNoTracking => Entities.AsNoTracking();

您可以执行以下操作。使用上下文和表示视图模型的模型，您可以像这样从存储过程中提取数据。

List<UserInRoleVM> users = new List<UserInRoleVM>();
using (var context = new DataContext())
{
   SqlParameter Parameter = new SqlParameter("@p0", code);
   users = context.Database.SqlQuery<UserInRoleVM>("exec usp_GetUsrsofRole  @p0", Parameter).ToList();
}
return users;

不确定是否重要，但是在存储过程中，确定其RoleID，在模型中确定其RoleId。不知道是否有所作为。
