ht.Add("key2", object2);<br />
ht.Add("key3", object3);<br />
<br />
foreach(DictionaryEntry de in ht)<br />
{<br />
WriteLine(de.Key);<br />
}<br />
<br />
------------------<br />
result can be as this:<br />
<br />

key2<br />
key3<br />
<br />

I don't believe so, no. A hash table, by definition, stores according to hashes. If you need the order, you need to store them in a list or something as well.

 I belive in what i saw
When in watch window i debug this hashtable i saw what all entries walk in ordem in which i add ones .Since what i think should exist any mechanism for retrive ones in same ordem.
Please ,any key ,get me opinion :
i need any ordered collection and simulatently
key-value-pares in one. Which type of collection i should use.
Thank.

A hashtable does not retain the order that the items were added in. If the items were displayed in the same order you added them, it was a coincidence.

b { font-weight: normal; }

You can make sure in this. Try to oneself.
When displayed items in ordem, when retrived not.
ht.Add("one", null);
ht.Add("two", null);
-----
Displayed:
ht
["one"]
["two"]
------
Retrived
two
one

Use SortedList instead of Hashtable.

hi all i have this pro on hand now.. i have downloaded some sample database applications from the internet..however when i want to debug it i gives me the error--An unhandled exception of type "system.Data.OleDb.OledbException" occurred in system.data.dll
and also the database is in access format but when i want to open it it gives a message--the file is located outside yr intranet or on an untrusted site. Microsoft Access will not open the file due to potential security problems.TO open the file, copy it to yr machine or an accessible network location.
i inferred that this errors occur due to where the dB file is located..is it correct? can someone out there help will this pro? and maybe guide me to correcting it ..thanks in advance..

Probably you need to right click the MDB file and mark it as trusted, it's probably marked as having come from the web.

I doubt that very much. It sure has nothing to do with C#.

Hello,
Im wondering how to merge two different List<> into one?
List1
1, Green
2, Blue
3, Red
4, Black
List2
1, 11
2, 22
3, 33
4, 44
result
List1 (after merge)
1, Green, 11
2, Blue, 22
3, Red, 33
4, Black, 44
I now it´s possible in C# 3.0 (http://blogs.msdn.com/abhinaba/archive/2005/09/15/467926.aspx) but i cant use that! It must be a way to solve this, I don´t give up;)

The article shows the use of extension methods and the presented Merge method doesn't merge the two list as you're planning to do it. It only appends the elements of the second list to the first one.
In your case after the merging List1 has a different type (3 values per entry instead of 2). Of what type are the elements of these lists? By what you provided it seems they all are of different types, so I think it would be best to create a third list by iterating over the first two and creating the elements of the third list from their elements.

List 1 has class with construcors so yes we can reuse List 1 in my case.
List1(int, string)
List1(int, string, int)
So Im wonder HOW to merge these two lists. Like Joins in SQL
please any idea
|

I think the best would be iterating over the lists and either create new items or assign the second int if accessible.
for (int index = 0; index < List1.Length; index++)
{
List1[index] = new Class1(List1[index].firstIntVar, List1[index].string, List2[index].SecIntVar);
List1[index].SecIntVar = List2[index].SecIntVar;
}

well guys hello!!
jus wanted to know that there is compiles project i got from my senior, but it has not database and gives me errors, i feel like not makin whole of the tables again.. i found there is a file with .pdb extension in debug folder, "program debug database" .
Is it the real database, or what it is ??
can u help me guyzz
<<realin wuz="" here="">>

As the name implies the pdb-file holds information for debugging (afaik to give you filenames and linenumbers if errors occur). So either you get the "real" database from your senior or you'll have to rebuild it.

All jokes aside, what do you mean by that? There are many sources in the internet that provide completed projects for certain purposes (CP is only one of them).
