Created Issue: Add int.Seconds and so on [6763]

Ornus — Mon, 13 Feb 2012 17:33:08 GMT

Sometimes it's handy to quickly convert number to TimeSpan. Something like should do the trick. It'll allow me to do 10.Seconds()

public static TimeSpan Seconds( this int seconds )
{
return TimeSpan.FromSeconds( seconds );
}

Commented Issue: Add IEnumerable< string >.Join [6756]

JamesCurran — Fri, 10 Feb 2012 20:48:32 GMT

there's a string.Join method. It would be nice if an extension would be available for it.

something similar to:

public static string Join(this IEnumerable<string> strings, string separator)
{
if (strings == null) throw new ArgumentNullException("strings");
if (separator == null) throw new ArgumentNullException("separator");
return string.Join(separator, strings.ToArray());
}

Actually, this already exists in .NET 4 (It's in the Enumerable class)

Appologies for double post.

Cool. I'm glad you got it working.

happy coding!

My bad, I change the Target framework from ".NET Framework 4 Client Profile" to ".NET Framework 4" and it's ok.

No reference to System.Web is needed.

Hi Tuizi,

Have you got references to System.Web in your project?

Try it and let us know if it work for you.

Hello,

I'm just adding this library with NuGet.

I see all the extensions in Intelliscence but, when I'm using a method, I can't compile!

For exemple, Im using the method CanConvertTo<> on my string variable, and I get the error:

Error 1 'string' does not contain a definition for 'CanConvertTo' and no extension method 'CanConvertTo' accepting a first argument of type 'string' could be found

What's wrong?

This is awesome. Thanks so much for pushing a patch. I came back to check if there was any progress made on the issue. I hope Patrick will consider your patch.

I like your conservative approach with Object.

Commented Issue: Add event.Raise extensions [6180]

Ornus — Wed, 18 Jan 2012 19:11:16 GMT

Checking for null in events every time sucks. It'd be nice if there would be extensions (simple and supporting generic event args) to make event invocation easier.

Example of what I'm talking about (from my code I frequently use in projects):

/// <summary>
/// Call to raise generic event.
/// </summary>
/// <param name="eventHandler">The event handler.</param>
/// <param name="source">The source.</param>
public static void Raise( this EventHandler eventHandler, object source )
{
if( eventHandler != null )
eventHandler( source, new EventArgs() );
}
/// <summary>
/// Call to raise event with specific event arguments.
/// </summary>
/// <typeparam name="T">Event arguments type.</typeparam>
/// <param name="eventHandler">The event handler.</param>
/// <param name="source">The source.</param>
/// <param name="e">The event arguments.</param>
public static void Raise< T >( this EventHandler< T > eventHandler, object source, T e ) where T: EventArgs
{
if( eventHandler != null )
eventHandler( source, e );
}

/// <summary>
/// Call to raise event in response to a property being changed.
/// </summary>
/// <param name="eventHandler">The event handler.</param>
/// <param name="source">The source.</param>
/// <param name="propertyName">Name of the property.</param>
public static void Raise( this PropertyChangedEventHandler eventHandler, object source, string propertyName )
{
if( eventHandler != null )
eventHandler( source, new PropertyChangedEventArgs( propertyName ));
}
Comments: ** Comment from web user: Ornus **

While initializing with blank delegate is one workaround, it has it's own drawbacks: http://stackoverflow.com/questions/840715/the-proper-way-of-raising-events-in-the-net-framework

Commented Issue: ExtractDigits [6587]

JamesCurran — Fri, 23 Dec 2011 15:03:55 GMT

Browsing through the code, I noticed that I could improve ExtractDigits. Below are two different improved version.

ExtractDigits3 is fastest overall, but ExtractDigits2 is easier to read. Both are significantly faster than the current version.
Normalized timings:
ExtractDigits (current) 6.27
ExtractDigits2 1.31
ExtractDigits3 1.00

public static string ExtractDigits2(this string value)
{
return string.Join(null, value.Where(Char.IsDigit));
}
public static string ExtractDigits3(this string value)
{
return value.Where(Char.IsDigit).Aggregate(new StringBuilder(value.Length), (sb, c) => sb.Append(c)).ToString();
}

New Post: Subversion, missing some files when getting latest

nathankoop — Fri, 16 Dec 2011 18:00:15 GMT

Hey there,

Just wanted to peek at the code and try and help with some stuff.

I'm running VS2010 and subversion. I used the subversion link from the Source Code tab (https://dnpextensions.svn.codeplex.com/svn) and it grabbed a lot of files, however it doesn't have some that it seems to expect.

The project PGK.Extensions.Benchmark is unavailable, there is no file nor any folder for that code, I checked via the TortoiseSVN repo browser and saw a number of files, but that folder doesn't appear to be there

The following files in PGK.Extensions.Tests, are unavailable (and not in the SVN repo)

CollectionExtensionsTest
ComparableExtensionsTests
DirectoryInfoExtensionsTest
TextReaderExtensionsTest
Used_for_testing.txt

These appear to be all the files that I'm missing. I was wondering if:

a) these files are no longer required, but still accidentally in the project

b) these files are required and for some reason aren't in the repo

c) I screwed up the retrieving of code

Thanks,

Nathan

I believe this should be in fixed or closed status

Created Issue: GetOriginalException reproduces .NET GetBaseException [6672]

ConcreteGannet — Mon, 12 Dec 2011 01:18:20 GMT

The GetOriginalException extension method for System.Exception appears to reproduce the GetBaseException method from .NET (http://msdn.microsoft.com/en-us/library/system.exception.getbaseexception.aspx)

It should be removed or deprecated.

Lots & lots of new Unit tests (tripling total number of tests). Fixes to some bugs found by unit tests. Plus a few optimizations.

PatrickLorenz — Wed, 07 Dec 2011 10:46:45 GMT

Hi there!

I assume you are right.

Would you like to submit a bug so I could assign it to the origin developer of the method?

Thanks, Patrick
