有兩個類：public class User{public int Id { get; set; }public string Name { get; set; }}public class UserDto{public int Id { get; set; }}如何將：Expression<Func<UserDto, bool>> exp = item => item.Id.Equals(0); 轉(zhuǎn)換成Expression<Func<User, bool>>

轉(zhuǎn)換不了的，還是用接口實際點

public interface IUser{ int Id{get;set;}} public class User:IUser{ public int Id { get; set; } public string Name { get; set; } }public class UserDto:IUser{ public int Id { get; set; } }
