List c sharp中的错误 [英] Error in List c sharp

问题描述

using System.Collections;
using System.Collections.Generic;

/// <summary>
/// Summary description for BookManager
/// </summary>

public class BookManager
{
    public List GetBooks ()
    {
        List list = new List();

        list.Add(new Book(101, "Java", 34.99));
        list.Add(new Book(102, "HTML", 31.99));
        list.Add(new Book(103, "XSLT", 37.99));
        list.Add(new Book(104, "XML", 59.99));
        list.Add(new Book(105, "XHTML", 35.99));
        list.Add(new Book(106, "CSS", 35.99));

        return list;
    }
}

- 错误1使用泛型类型' System.Collections.Generic.List< t>'需要'1'类型参数

--Error 1 Using the generic type 'System.Collections.Generic.List<t>' requires '1' type arguments

推荐答案

改为使用fllowing line：

Use the fllowing line instead:

List<Book> list = new List<Book>();

您已包含 Generic 命名空间。



更改;

You've included the Generic namespace.

Change;

public List GetBooks ()
{
    List list = new List();

    list.Add(new Book(101, "Java", 34.99));
    list.Add(new Book(102, "HTML", 31.99));
    list.Add(new Book(103, "XSLT", 37.99));
    list.Add(new Book(104, "XML", 59.99));
    list.Add(new Book(105, "XHTML", 35.99));
    list.Add(new Book(106, "CSS", 35.99));

    return list;
}

要

To

public List<Book> GetBooks ()
{
    List<Book> list = new List<Book>();

    list.Add(new Book(101, "Java", 34.99));
    list.Add(new Book(102, "HTML", 31.99));
    list.Add(new Book(103, "XSLT", 37.99));
    list.Add(new Book(104, "XML", 59.99));
    list.Add(new Book(105, "XHTML", 35.99));
    list.Add(new Book(106, "CSS", 35.99));

    return list;
}
