I certainly wouldn't use Split or Reverse.
Substring and LastIndexOf maybe, but what if you get something like:
System.Collections.Generic.List<System.Int32> ?

Well, the goal of this is to be able to access the application user settings at runtime without having the developer do anything.
So for example, in my prior example, I have:
A.B.C.WpfApplication3.App
that class derives from my "ApplicationEx" class.
So in ApplicationExs constructor, I want to mess around with A.B.C.WpfApplication3.Properties.Settings.Default and do stuff with the settings. So I kind of need to figure out the namespace of the settings class at runtime so I can use reflection. I guess there can be cases where they don't match up like that... but having the user pass in the type or namespace string seems kinda cheezy.

I think that falls under the just because you can doesn't mean you should category.

I wouldn't recommend it, but if you want to play with some code, here you go:
string result = (from pos in new int[] { (str ?? string.Empty).LastIndexOf('.') } select (str ?? string.Empty).Substring(0, pos >= 0 ? pos : 0)).First();
One line, only calls LastIndexOf once, handles a null input string, and handles the case that a period doesn't exist in the string.

You mean it "quietly goes on about its business"?

Some tweaks:
string result = string.IsNullOrEmpty(str) ? str : (from pos in new int[] { str.LastIndexOf('.') } select str.Substring(0, pos >= 0 ? pos : str.Length)).First();

How about: Regex.Replace("A.B.C.WpfApplication3.Application", "\.\w*$", "")
Ok it's oldschool, but still cool right? (right?)
Or if you want to allow weird chars: Regex.Replace("A.B.C.WpfApplication3.Application", "\.[^\.]*$", "")

I suspect those will remove more text than you think. Maybe toss a ^ or $ at the end (whichever of those matches the end of a string).

No they match exactly the right amount.. just not at the right place.

He has the $ at the end -- think of the money shot.

Strangely, he also has [modified] at the end. Weird.

I can see you've got lots of solutions for the "trimming the string" task, but what I am curious about is:
Once you have the final string, how are you going to cast/transmute that into a usable reference to the current running application's settings: in your own words: "access the application user settings at runtime without having the developer do anything" ?
If you are the creator of the Application, isn't it possible for you, in the app initialization code to set a reference to the App's settings, to use later ?

I won't bore you with the full details of why I'm trying to do this because that'll be a long winded explanation . To summarize it in one sentence: I'm writing an application framework library and I currently instruct users to "copy these 4 lines into your startup code and modify the namespace to handle this specific scenario".
The code they copy is basically 4 lines that look something like:
WpfApplication3.Properties.Settings.Default...
I'd like to update my framework so they no longer have to do that. I already have an 'ApplicationEx' class that they derive from.
So, what I do is, in the ApplicationEx constructor, I do:
string type = this.GetType().ToString(); // this is going to give me something like "WpfApplication3.App"
I then take "WpfApplication3.App" and use the string manipulation stuff above to get the string "WpfApplication3.Properties.Settings".
I then do:
Type t = Type.GetType("WpfApplication3.Properties.Settings"); // Type.GetType is a static method in the Type class
that gives me the type of the settings class. The settings class (as generated in VS) has a static public property called Default that returns the instance, so I simply use reflection to get the PropertyInfo of that property and invoke the getter and viola... I've got an ApplicationSettingsBase reference to the settings class .

+5 Enjoyed the explanation, and that's clever code

Hi,
I have tried to deploy my web application (VS2010 + C#) by adding the project output and building a msi setup. But, I want to do these steps through command prompt. Our command scripts will do all the stpes to deploy in server.
That command prompt scripts should do the following things
1. Getting latest version of my solution
2. Adding web deployment project and adding project outputs there
3. Building and deploying in a server..
How to do these things thorugh command prompt only?
Thanks in advance.
Balasubramanian K.

If you are speaking of using a console window with command prompts to do an update and/or installation with all the complexity you describe to a server: how many years do you have to finish this project ?
If you don't have years, maybe check out ClickOnce, via search here on CP.

Maybe learn to use MSbuild? I dunno.

That depends on the type of source-control that you're using. I described the steps to download source from sourcesafe here[^], as part of a daily build script. There are similar options for other source-control systems like tortoise and SVN. Simply google the productname and "get source commandline".
BalasubramanianK wrote: 2. Adding web deployment project and adding project outputs there
You don't point the project output there, you COPY the resulting assemblies. Don't mess around with settings if you don't have to.
BalasubramanianK wrote: 3. Building and deploying in a server..
You can generally deploy using XCOPY, using REGASM for assemblies and REGSVR32 for COM-server that need be registered. Building can be done using the IDE and some commmand-line options, but it would be recommendable to use MSBuild[^], as suggested by PIEBald.

Have you tried a Google search?

In general, or for this question in specific? If the latter, I suspect we all know the answer.

Both I guess; I just wonder why people think it faster to post a Google search into CP rather than the obvious place. Ho-hum.

Because it's easier to get us to do their thinking for them.
