C# Arraylist with class

c# arraylist of class

Dear Sir:
Im new to C# and Im trying to assign multipe object into Arraylist and the code as follow:
using System;
using System.Collections;


class contact
{
public string Name
{
get
{
return name;
}

set
{
this.name=name; //should this be Name=value;?
}
}
string name;
public string Status
{
get
{
return status;
}
set
{
this.status=status;
}
}
string status;

public void Setdate ( string status, string name)
{
this.status = status;
this.name = name;
}
}
class entry
{
public static void Main()
{
contact obj = new contact();
ArrayList container= new ArrayList(100);


obj.Name = "John";
obj.Status = "Online";


container.Add(obj); // I want to pass it into ArrayList, but exception

obj.Name = "Peter";
obj.Status = "OFFLINE"; // Now i create another obj and want to store into the ArrayList

container.Add(obj); // so now should have multiple object contain inside the ArrayList?
for (int i=0; i<container.Count; i++)
Console.WriteLine("{0} ", container); // How do i print it out?

}
}

There is a lot of mistake in above code, but what i really want to do is trying to assgin multiple "contac" object into Arraylist. So, if there is any advice is wellcome.

thanks!

Louis

counting multiples in a c# arraylist

Hi,
i have fixed the issues in your bug and left for you to analyze what i have modified, analyze it and try to think why this was done.

using System;
using System.Collections;

class contact
{
public string Name
{
get
{
return name;
}

set
{
name=value;
}
}
string name;
public string Status
{
get
{
return status;
}
set
{
status=value;
}
}
string status;

public void Setdate ( string status, string name)
{
this.status = status;
this.name = name;
}
}
class entry
{
public static void Main()
{
contact obj1 = new contact();
contact obj2 = new contact();

ArrayList container= new ArrayList(101);


obj1.Name = "John";
obj1.Status = "Online";


container.Add(obj1); // I want to pass it into ArrayList, but exception

obj2.Name = "Peter";
obj2.Status = "OFFLINE"; // Now i create another obj and want to store into the ArrayList

container.Add(obj2); // so now should have multiple object contain inside the ArrayList?

for (int i=0; i<container.Count; i++)
Console.WriteLine("Name = {0} Status = {1} ", ((contact)container).Name,((contact)container).Status); // How do i print it out?

}
}
