本文介绍了如何遍历对象,因为foreach不能与对象一起使用。的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace oops1
{
class Program
{
static void Main(string[] args)
{
string strdetail = "Anurag Nayak 8585916787";
B b1 = new B();
object obj= b1.Split(strdetail);
}
}
class B
{
public object Split(string str)
{
String[] strarray = new String[3];
strarray = str.Split(' ');
API p = new API();
p.firstname = strarray[0];
p.lastname = strarray[1];
p.mobilenumber = strarray[2];
return p;
}
}
}
---I return an object from Split function.
--- object obj= b1.Split(strdetail);
How to iterate through the obj.
-- I was trying foreach. But foreach cannot be used with objects.
Kindly suggest
。
推荐答案
试试这个
Try this
string strdetail = "Anurag Nayak 8585916787";
B b1 = new B();
object obj = b1.Split(strdetail);
API api = obj as API; // casting the object to Type API
string firstname = api.firstname;
string lastname = api.lastname;
string mobieno = api.mobilenumber;
B类似乎多余的,您可以将其简化为:
Class B seems redundant, you could simplify this to something like:
namespace oops1
{
class Program
{
static void Main(string[] args)
{
string strdetail = "Anurag Nayak 8585916787";
string[] details = strdetail.Split(' ');
API p = new API(details);
}
}
public class API
{
public string Firstname
{
get;
set;
}
public string Lastname;
{
get;
set;
}
public string Mobilenum;
{
get;
set;
}
public API(string [] details)
{
Firstname = details[0];
Lastname = details[1];
Mobilenum = details[2];
}
}
}
您现在可以打印任何字段,例如
You can now print any of the fields with a statement such as
Console.WriteLine("name is: {0} {1}", p.Firstname, p.Lastname);
当拆分返回时,为什么需要将其转换为对象 数组字符串。
试试这个
Why do you need to convert it into object when the split returns array string.
Try this
string strdetail = "Anurag Nayak 8585916787";
B b1 = new B();
string[] str= b1.Split(strdetail);
然后使用迭代使用如下: -
then to use iteration use like this:-
for(int i=0;i<str.length;i++)>
{
//do your work
}
