Fine, I'll jump on the "I hate Microsoft" bandwagon

Here you go:
public static string Left(this string theString, int length) { int sz = length > theString.Length + 1 ? theString.Length:length; return theString.Substring(0, sz); }Don't forget the null check! And a small tweak because I like doing it this way :P It's called Truncate in my library, but if you're from VB, I guess Left is ok... Or you could just reference the Microsoft.VisualBasic assembly!
public static string Left(this string target, int length)
{
if(string.IsNullOrEmpty(target) //could just do == null; condition below caters to empty (which is faster I wonder)
return target;return target.SubString(0, Math.Min(target.Length, length));}

Oh my, you are the quick to hate type, are you not? One tiny method missing and *boom* I hate you MS! That escalated rather quickly! :O At any rate I give you here, free of charge, a solution to use for your own coding pleasure! No, no, no, there is no need to thank me!
public static class StringExtensions {
public static string Left(this string s, int n) {
if (n >= s.Length)
return "";
return s.Substring(s.Length - n);
}

Looks like a 'Right' to me, rather than a 'Left' :)

So, C# has no left method on a string? :omg: :omg: It would be so easy to add one, lazy Microsoft C# developers. So, use substring. Whoops. Nope. Errors if you give it a length that is longer than the string. I miss VB. :sigh:

Yesterday I noticed one of our projects has a reference to Microsoft.VisualBasic. What the...? Upon closer inspection I found it was needed for
new My.Computer.Devices.ComputerInfo().TotalPhysicalMemory(). Looked around on the web, and there really isn't an easy C# variant :sigh:Read my (free) ebook Object-Oriented Programming in C# Succinctly.

Excuse me but: Several GB worth of Framework, poorly documented, with an inextricable Hell of dependencies and Assembly idiosyncrasies and seemingly duplicated functionality which should live in the same ecosystem but are as incompatible as coffe and salt... and I have to write my farking own version of a function that existed 20 years ago to do the easiest and stupidest thing on Earth? So much for The Framework™.

I am still wondering if you are really throwing a tantrum for a "missing 2 lines function" or it is in fact a joke!? Haha! :laugh: Your seemingly deep anger make it all the more laughable! haha! :wtf: :rolleyes: :laugh:

My tantrum is directeed to the pile of sunshine that is the .NET framework, in fact I usually make my own libraries anyway. Still for a "framework" so bloated not having a simple and fundamental function is basically an indication of utter failure.

You tried to sneak that one there. return "". How dare you. :mad:

While MS gave you the power of Linq in C#....this gives you an infinite amount of possibilities. That combined with extensions, and you are so much better off than with VB! It's true, you'll have to spend 2 minutes of your personal precious time to write this code once, and to remember to add this extension 'lib' to all your projects where you might need them....boohoo. Sth like this... one line of code...
public static string Left(this string inputString, int length) { return new string((from ch in inputString select ch).Take(length).ToArray()); }
Now you can just Left a string by doing string.Left(5)....so easy but 1000 times more powerful (and prob as many times more performant) than VB....

Exactly!

Well it'll be less now if you just copy/paste the code....I think 30 secs will do now. Is prob just about as much as VB would need to show you its 'intellisense' info on the Left function ;-)

My point is, why after all these years have the C# builders not added it in. It would only take a few minutes of their time.

I understand your frustrations, but to be honest, I didn't ever miss that function. I did VB6 for years, I did Java for years, even did some Delphi, but now C# for quite some years, and every language has its benefits and its downsides, but C# really is the nicest language I've used, Delphi comes in second :-) The reasoning behind not providing a Left function I think is since it's not a core function, but more of a "convenience function", one that would give discussions among developers, since they would make their own 'more performing' version of that function. VB6 provided more convenience functions out of the box, since it was mainly meant to make software development 'as easy as possible'. And to be honest, I like the fact that C# provided us with Extensions, Linq, Entity Framework,... more than the couple of arguable functions they might have 'forgotten'. Here they were really one of the first to incorporate these new ideas, where Java now tries to catch up...

Actually, I don't think you do, but that is my fault. I think a lot of other people thought I was seriously "hating" on Microsoft. My original post was done tongue-in-cheek. I do find it weird that they don't have the LEFT method on a string but it doesn't actually bother me at all. I just wanted to get in on all the hating going on with something silly. :-\ But, you do make good points.

For one, VB teaches its users to take shortcuts. Like leaving words out of your sentences, and then taking for granted that others will understand what you meant just by context.
Well it seems to me that documenting your code resolves that issue. AND it is easier and quicker to do, and still more productive. Bad programmers will always "take shortcuts". Do not blame that on VB, or any other language, for that matter. The language, any language, doesn't "teach" anything, to a programmer. If you shoot yourself in the foot with a handgun (after completing the required safety training), is it the gun's fault? VB's problem is that it is not "Hip" anymore. Go listen to Billy Joel's "Still Rock and Roll". It is universally applicable.
