Given two IEnumerables of the same size, how can I convert it to a Dictionary using Linq?
IEnumerable<string> keys = new List<string>() { "A", "B", "C" };
IEnumerable<string> values = new List<string>() { "Val A", "Val B", "Val C" };
var dictionary = /* Linq ? */;
And the expected output is:
A: Val A
B: Val B
C: Val C
I wonder if ...

Hi,
In .NET Framework, there are some classes which use SomethingCollection syntax.
For example, when dealing with SqlCommand, it has a parameter Parameters of type SqlParameterCollection. Since it does not have a form of IEnumerable<SqlParameter> (or IList<SqlParameter> or something similar), it is impossible to write:

Hello,
I have List which has 150K elements. Average time of work IndexOf() is 4 times lower than Contains(). I tried to use List of int. For List of strings IndexOf is a bit faster.
I found only one main difference, it's attribute TargetedPatchingOptOut. MSDN tells:
Indicates that the .NET Framework class library method to which th...
I was having a discussion with a co-worker over whether it is better to use a Dictionary and repopulate it whenever a result set changes or to just use linq loop over all elements in the list each time.
We're trying to map a parent / child relationship, and I suggested using the ParentID as the dictionary key, and the dictionary value a...

Given a Type object in .NET, is it possible for me to get the source code filename? I know this would only be available in Debug builds and that's fine, I also know that I can use the StackTrace object to get the filename for a particular frame in a callstack, but that's not what I want.
But is it possible for me to get the source code ...

I am reading existing posts on Generics at SO. If Generics has so many advantages like Type safety, no overhead of boxing/unboxing and it is fast, why not always use it. Why to go for a non-generic thing?
Edited (Question further extended below)
I am a bit confused. The last time I read about Generics, months back, I read that if the T...
