不能隐式地将类型string转换为int ISSUE
本文关键字:转换 int ISSUE string 类型 不能 | 更新日期: 2023-09-27 17:50:20
这是我的c#代码问题在get属性中。当我尝试返回时,它告诉我它不能将类型字符串转换为int
!我试着找出问题的答案,但仍没有解决办法。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace DefiningProperties
{
class BookPrices
{
private string Name;
private int MarketPrice;
private int Sale;
private string Aouther;
public int price
{
get
{
return MarketPrice * Sale;
}
set
{
MarketPrice = value;
}
}
public int BookDispay
{
get
{
strong text return Name + ", " + price + ", " + Aouther;
}
}
public BookPrices(string bName, int bMarketPrice, int bSale, string bAouther)
{
Name = bName;
MarketPrice = bMarketPrice;
Sale = bSale;
Aouther = bAouther;
}
}
}
}
您的属性类型是int
,但您试图返回string
。
From
public int BookDispay
public string BookDispay
属性签名错误
您将其声明为Int
并返回String
将Int
替换为String
问题:您没有私有string
字段bookDisplay
。
解决方案:您需要创建一个私有字符串字段bookDisplay
,然后写入公共属性来设置并获取私有bookDisplay
字段的值。
试试这个:
class BookPrices
{
private string bookDisplay; //add this private field.
public string BookDispay // now create a public property here
{
get
{
bookDisplay = Name + ", " + price + ", " + Aouther;
return bookDisplay ;
}
}
