Collection<T> Sort/Search Introduction
Generated Source Code Base Class
System.Collections.ObjectModel.Collection<T>
Description
The Collection<T> (Collection(Of T) in Visual Basic)
base class provides the functionality for a "basic" collection. Unlike
the non-generic collection base classes, Collection<T> is not
abstract and it can, therefore, be used as is. The generated source code provides
a closed constructed type, derived from the Collection<T> base
class that enhances the basic functionality by adding the following members: IsReadOnly,
IsSorted, SortDirection and SortProperty properties,
AddRange, AsReadOnly and overloaded BinarySearch, Find,
FindAll, Reverse, Sort and TrueForAll
methods.
The Collection<T> Sort/Search generated source code depends on the
PropertyComparer<T> class to search and sort collected items on the value of a
specified property. You can generate the collection class source code with or without the
PropertyComparer<T> class. This option is provided to allow you to generate
more than one Collection<T> Sort/Search collection without paying for
multiple copies of the PropertyComparer<T> class. In this situation you can
generate the PropertyComparer<T> class with the first collection and then
generate the other collection classes without the comparer class. However, if you are only
generating a single collection, you must specify the option that includes the PropertyComparer<>
class.
Generated Source Code .Net Framework Version Compatibility
Versions: 3.5, 3.0 and 2.0
Generation Properties
You will be required to select/specify the following values in the generation
property wizard as part of the source code generation process:
| Property |
Description |
| Language |
You can generate either CSharp or Visual Basic source code |
| Collected Class Name |
The Type or Class name of the objects that are to be stored in the collection |
| Collection Class Name |
The Type or Class name of the collection |
| Namespace |
The collection class namespace (CSharp only) |
| Find Property Name |
The name of the collected class property to use when searching the collection |
| Default Sort Property Name |
The name of the default sort property |
| String Comparison |
The string comparison to use when searching the collection using the value of a
string property
|
| Allow Null Items |
Specify True if the collection is to allow null items to be added, False if not |
Note
If a value type is specified as the collected class, the private, FindItem
method has to be modified to remove the check for a null item.
If the collected class is not in the same namespace as the collection
class, a using (Imports in Visual Basic) statement will
need to be added to the generated source code.
Visual Basic Only
If the collection class is not in the default (project) namespace
i.e. it is in a sub-namespace, a Namespace statement will need
to be added to the generated source code.

Order Information
We guarantee that you will get the source code that you have paid for. In the unlikely
but possible event that the transfer back to this site from our payment processor
fails, we will reactivate the source code generator transaction so that you can
complete the process and generate your source code.
To reactivate a paid for but failed source code generator transaction:
- Direct your browser back to the Blayd Software website
- Follow the "Contact Us" link in the footer of any of the site's pages or go directly
to the Support Section, where you will find the Contact Us links
- Use the "Code Generator Enquiry" link to email your order reference and a brief
description of the problem to us
We will then email a reactivation link to you so that you can complete the generation
process and get your source code.
Important
Please make a note of your order reference before clicking the "Buy Now" button.
You can either note the reference down or select the reference on the page and copy
it to the clipboard, then paste it into a text editor and save to file.
If you are not intending to pay using a PayPal account, you
must return back to this site, using the option provided on
the PayPal site. If you do not return directly from the PayPal site to this site
you will not be able to generate your source code (see above for details of how to
reactivate a failed transaction).
