寻找物体 [英] searching for objects

问题描述

我正在设计一个库系统，可能需要使用以下调用搜索存储在基于对象的数据模型中的数据对象：

I am designing a library system, which may require the searching of data objects stored within an object-based data model, using the following calls:

public String search(String searchTerm) { return "Not found"; }
 public ulong search(ulong MediaID) {//TODO }

private ulong mediaID;
    private ulong ContactID;
    private DateTime TakenOn;
    private DateTime ReturnBy;

    public void addItem(BooksAndMediaOnLoan BooksAndMediaOnLoan) { this.BooksAndMediaOnLoanToCustomers.Add(BooksAndMediaOnLoan); }
    public void removeItem(BooksAndMediaOnLoan BooksAndMediaOnLoan) { this.BooksAndMediaOnLoanToCustomers.Remove(BooksAndMediaOnLoan); }
    private List<BooksAndMediaOnLoan> BooksAndMediaOnLoanToCustomers = new List<BooksAndMediaOnLoan>();

你会怎么建议呢？

How would you suggest going about it?

推荐答案

Linq，可能。

Linq, probably.

return BooksAndMediaOnLoanToCustomers.Where(b => b.mediaId == mediaId).ToList();
