On the VB tab, it gives the VB syntax:
Public Shared Function Left (
str As String,
Length As Integer
) As StringOn the C# tab, it gives the C# syntax:
public static string Left(
string str,
int Length
)I know that computery things seem complicated, Granny, but you ought to at least try to use them.

Is there a chapter and verse that gives a get-out from wearing flares and an afro?

Maybe...
Deuteronomy 22, 5:
A woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment...
Skipper: We'll fix it. Alex: Fix it? How you gonna fix this? Skipper: Grit, spit and a whole lotta duct tape.

You're still missing what namespace the function is in. :doh:

Don't bother me with petty details when I'm in panic mode! Looks like I've always used Substring, anyway. Strange, that. It feels like I've used Left much more recently than I've used VB. {Insert Sid James comment here]

That's close enough for me!

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:

Oh, there is, but the definition of the word "music" has changed to be something to do with money for nothing.

You nailed it! In a few words you nailed it! Modern music is nothing and worth nothing! Now: How are we going to convince poor souls like Sander that this is true? :-D

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); }
No need to call
Substring
if thelength
is greater than (or equal to) the string's length. And you'll get aNullReferenceException
if the string isnull
, whereas VB would return an empty string instead. Seems like an odd choice, but when you're pandering to these VB devs... :rolleyes:public static string Left(this string theString, int length)
{
if (length < 0) throw new ArgumentOutOfRangeException(nameof(length));
if (theString == null || length == 0) return string.Empty;
if (theString.Length <= length) return theString;
return theString.Substring(0, length);
}Now, let's hope he doesn't ask for a C# version of this VB6 abomination:
Dim s As String = "He11o"
Mid$(s, 3, 2) = "ll"

As one would jolly well hope it did. I don't see why MS should take stick for your faulty programming logic.

While I cherish the myriad weirdnesses I am aware of in my long-term relationship with C#, the absence of 'Left would not qualify. Welcome to Linq: [^]. Unless there's something you just can't stand about the word: "Take" ? :) cheers, Bill
«There is a spectrum, from "clearly desirable behaviour," to "possibly dodgy behavior that still makes some sense," to "clearly undesirable behavior." We try to make the latter into warnings or, better, errors. But stuff that is in the middle category you don’t want to restrict unless there is a clear way to work around it.» Eric Lippert, May 14, 2008

These are the string extension methods I wrote ages ago (well, since extension methods have been around): (Note that some of this isn't very elegant, could be LINQ'ified, could be optimized, etc.)
/// /// Returns a new string surrounded by single quotes. /// public static string SingleQuote(this String src) { return "'" + src + "'"; } /// /// Returns a new string surrounded by quotes. /// public static string Quote(this String src) { return "\\"" + src + "\\""; } /// /// Exchanges ' for " and " for ' /// Javascript JSON support, which must be formatted like '{"foo":"bar"}' /// public static string ExchangeQuoteSingleQuote(this String src) { string ret = src.Replace("'", "\\0xFF"); ret = ret.Replace("\\"", "'"); ret = ret.Replace("\\0xFF", "\\""); return ret; } /// /// Returns the source string surrounded by a single whitespace. /// public static string Spaced(this String src) { return " " + src + " "; } /// /// Returns a new string surrounded by brackets. /// public static string Parens(this String src) { return "(" + src + ")"; } /// /// Returns a new string surrounded by brackets. /// public static string Brackets(this String src) { return "\[" + src + "\]"; } /// /// Returns a new string surrounded by brackets. /// public static string CurlyBraces(this String src) { return "{" + src + "}"; } /// /// Returns everything between the start and end chars, exclusive. /// /// The source string. /// The first char to find. /// The end char to find. /// The string between the start and stop chars, or an empty string if not found. public static string Between(this string src, char start, char end) { string ret = String.Empty; int idxStart = src.IndexOf(start); if (idxStart != -1) { ++idxStart; int idxEnd = src.IndexOf(end, idxStart); if (idxEnd != -1) { ret = src.Substring(idxStart, idxEnd - idxStart); } } return ret; } public static string Between(this string src, string start, string end) { string ret = String.Empty; int idxStart = src.IndexOf(start); if (idxSta

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));
}

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

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. Visit my blog at Sander's bits - Writing the code you need. Or read my articles here on CodeProject.
