Types

For convenience, you can group the list in four different ways:

• Plain List

  Objects are displayed in a plain list. This is the easiest way to identify objects with the highest memory usage.

• Group by Namespace

  Objects are grouped by their namespace. This type of grouping is very convenient when you want to focus on determining issues in your own classes.

• Group by Assembly

  Objects are grouped by the assembly they come from. This type of grouping can also be used to separate your own classes from the system ones.

• Group by Interface

  Objects are grouped by interfaces they implement. If an object implements more than one interface, it will be displayed under each implemented interface.

You can filter out objects that are of no interest to your analysis by type .

You can make your search more efficient by using the following tips:

• Use CamelHumps. E.g. fo will return objects of both System.Drawing.Font and MS.Utility.FrugalObjectList types.

• Use special symbols, like wildcards and others. The full list is shown in the table below.

Special symbols and filter examples

Symbol	Description	Example
*	Wildcard	* All objects in the set
		sys.*.data All types and namespaces that match the pattern. E.g. System.Data, System.Windows.Controls.Datagrid, and System.Windows.Data.Binding.
		sys.*.data. Only namespaces that match the pattern. E.g. System.Windows.Data.Binding but not System.Windows.Controls.Datagrid.
Arrays
[]	Leave only arrays	str[] Arrays, containing str in their type or namespace. E.g. String[].
[, [,, ... or [,] [,,] ...	Leave only arrays of the specified or higher (if brackets are not closed) dimension	str[,, Arrays with the dimension 3 and higher containing str in their type or namespace. E.g. String[,,] and String[,,,].
		str[,,] Three-dimensional arrays containing str in their type or namespace. E.g. String[,,].
!a	Exclude arrays from the result	!a str Objects (excluding arrays) containing str in their type or namespace. E.g. String but not String[].
Generic type arguments
<	Leave only types with generic type arguments	str< Only objects containing str in their type or namespace and having generic type arguments. E.g. FileStreamStorage<Char> but not List<String>.
		<str Only objects containing str in their generic type arguments. E.g. List<String> but not FileStreamStorage<Char>.
<, <,, ... or <,> <,,> ...	Leave only objects with the specified number of generic type arguments	fun<,,> Objects containing fun in their type or namespace and having three generic type arguments. E.g. Func<String, Object, Object>.
		fun<str,,task Objects containing fun in their type or namespace and having three or generic type arguments that match the pattern. E.g. Func<Stream, IAsyncResult, TaskResult, EventArgs>.
!g	Exclude generic type arguments from the search scope	!g str Objects (that do not have generic type arguments) containing str in their type or namespace. E.g. String but not List<String>.
#c #struct #m #ns	Search by type, value type, method, or namespace.	#ns Feature Objects containing Feature in their namespace.

In the Types view, you can select the following subjects for further analysis:

• Objects of a certain type;

• Objects exclusively retained (dominated) by the whole object set.

note

The list supports multi-selection. To select more than one item, click desired items while holding the Ctrl key. To select a number of adjacent items, click the first one and then the last one while holding the Shift key. This will allow analyzing a set of Selected objects.
