Types
The Types view shows a list of objects in the selected object set. For convenience, all objects are grouped by their type: each row in the list represents a specific type. All objects of that type existing in the set are counted under this row. You can use the Types view to identify objects that consume too much memory or shouldn't be in memory.
The list consists of the following columns:
Name | Description |
---|---|
Type | Type name. |
Objects count | The number of objects of the same type. |
Bytes | The overall shallow size of objects in bytes. |
Minimum retained bytes | The overall size of all exclusively retained objects in bytes. This is a lower estimate of how many bytes will be freed if you remove all objects of a certain type. |
Example
Group objects in the list
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.
Filter objects
You can filter out objects that are of no interest to your analysis by type .
To narrow the list
Start typing the desired string pattern. dotMemory will highlight matching strings.
You can make your search more efficient by using the following tips:
Use CamelHumps. E.g.
fo
will return objects of bothSystem.Drawing.Font
andMS.Utility.FrugalObjectList
types.Use special symbols, like wildcards and others. The full list is shown in the table below.

Wildcard
*
All objects in the set
sys.*.data
All types and namespaces that match the pattern. E.g.
System.Data
,System.Windows.Controls.Datagrid
, andSystem.Windows.Data.Binding
.sys.*.data.
Only namespaces that match the pattern. E.g.
System.Windows.Data.Binding
but notSystem.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[,,]
andString[,,,]
.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 notString[]
.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 notList<String>
.<str
Only objects containing
str
in their generic type arguments. E.g.List<String>
but notFileStreamStorage<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 notList<String>
.#c
#struct
#m
#ns
Search by type, value type, method, or namespace.
#ns Feature
Objects containing
Feature
in their namespace.
Select objects for further analysis
In the Types view, you can select the following subjects for further analysis:
To select objects of a specific type
Do one of the following:
Double-click the type in the list.
Right-click the type and choose Open this object set.
After this, the selected object set is added to the Analysis Path and you can use other object set views to analyze the objects in more detail.
To select the objects that are exclusively retained by the analyzed objects set
Click the Open objects retained by this set button.
After this, the Exclusively retained objects subject will be added to the Analysis Path and the list of desired objects will be displayed in the Group by Types view.
