C

c Use the foreach statement to traverse the queue.

using system;

using ;

public class queuesw3static void main(string args)queue a = new queue(10);

int x = 0;

x++;foreach (int y in a);;

Traversal I know, but what the elements are, I don't know.

This is a traversal of a data set that I wrote.

dataset ds=;

datatable mytable = ;

addressname", ""));

statesname", ""));

foreach (datarow dr inif (dr["addresseeid"].tostring() == "0")

dr["addressname"] = "System administrator";

if (dr["states"].tostring()=="0")dr["statesname"] = "Normal";

It's the same way as C C++.,Isn't it a data structure problem?。。。 How you traverse in c c++, how you traverse in c...

The upstairs ones are correct, and the ones below can also be used.

listlist =new list(t refers to the type of element in the list) for(int i=0; ilist = new list()

foreach(string s in list)

Upstairs is correct. foreach for loop can be traversed The key is to simplify and not simplify.

Today, when I was studying, I learned about a new interface, enumeration, and of course the focus of today's writing is not this.

It's another interface mentioned in the description of this interface in the help document, the iterator, the specific content of this is not too much to explain here, because there is a sub-excuse below the listiterator The description of this interface I don't say too much here, I saw that this interface has a list in front, I must have thought that it is related to list, and now I really enter today's topic, Let's use this iterator to iterate through the contents of the list collection!

Before using this iterator to iterate through the contents of the collection, review the methods that were previously taught by the teacher at school.

Let's say for loop here.

for（int i=0;i<;i++）

That's it, and as for what you're going to do, you can go ahead yourself.

Suppose arr is an array or even an IENUMERABLE interface.

foreach(var v in arr).;

It should be possible to use reflex.

public class test

--fieldinfo fieldinfo = typeof(test).getfields();

foreach (fieldinfo info in fieldinfo)

namespace: using ;

using ;

The queue can only remove the first object, and if you want to remove an object, all the objects before it must be removed.

Method: dequeue().

If you want to remove an element, convert the queue to listlist l = new list(

1 All queues and stacks do not need to be traversed in most cases, because they were not designed for this function.

Each generic collection has its own use scenario.

If you want to traverse, either foreach or linq is fine, you don't need to toarray first

;The tostring() method of the obj is called.

All types of tostring() methods inherit from , and by default they output their own type names. So what you get is. But there are some types of tostring() methods that have been overridden override, such as string, int, long, double, single, and so on.

If you want to output the elements in the array, you need to iterate through the output in a loop.
