如何在Entity Framework6中将数字映射为双精度？

public class MyEntity
{
    public double Number { get; set; }
}

public class MyEntity
{
    public decimal Number { get; set; }
}

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<MyEntity>()
        .Property(e => e.Number)
        .HasPrecision(18, 2); // 设置精度为18位，小数点后保留2位
}

public class MyEntity
{
    [Column(TypeName = "decimal(18, 2)")]
    public double Number { get; set; }
}

// 查询操作
var entities = context.MyEntities.Where(e => e.Number > 10.0);

// 更新操作
var entity = context.MyEntities.FirstOrDefault();
if (entity != null)
{
    entity.Number = 20.0;
    context.SaveChanges();
}
