Method NoInstances

NoInstances(TypeSet)

Defines that no instances of any type in the provided typeSet should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(TypeSet typeSet)

Parameters

Type	Name	Description
TypeSet	typeSet	A TypeSet containing the types of the instances that should be checked.

Returns

Type	Description
AssertionsDefinition	Returns `this` to allow definition calls to be chained.

Remarks

Calling MemAssertion.MemAssertion.Assert using this AssertionsDefinition will fail if an instance of any type in the typeSet exists, unless the type is also included in a call to an AllowXXX or MaxXXX method.

note

The AllowXXX (AllowInstances(TypeSet), AllowNewInstances(TypeSet)) and MaxXXX (MaxInstances(TypeSet, Int32), MaxNewInstances(TypeSet, Int32), MaxBytes(TypeSet, Int64), MaxNewBytes(TypeSet, Int64)) methods takes precedence over the NoXXX (NoInstances(TypeSet), NoNewInstances(TypeSet)) methods. For more information see AssertionsDefinition.

NoInstances(Type[], Boolean)

Defines that no instances of the provided types (and optionally their subclasses) should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

Parameters

Type	Name	Description
System.Type[]	types	An array containing the System.Types that should be checked.
System.Boolean	includeSubclasses	Indicates whether instances of subclasses of the specified type should be checked.

Returns

Type	Description

Remarks

Calling MemAssertion.MemAssertion.Assert using this AssertionsDefinition will fail if an instance of the provided types (and optionally their subclasses) exists, unless the type is also included in a call to an AllowXXX or MaxXXX method.

note

NoInstances(Type[])

Defines that no instances of the provided types should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(Type[] types)

Parameters

Type	Name	Description
System.Type[]	types	An array containing the System.Types that should be checked.

Returns

Type	Description
AssertionsDefinition	Returns `this` to allow definition calls to be chained.

Remarks

Calling MemAssertion.MemAssertion.Assert using this AssertionsDefinition will fail if an instance of the provided types exists, unless the type is also included in a call to an AllowXXX or MaxXXX method.

note

NoInstances(Type, Boolean)

Defines that no instances of the provided type (and optionally its subclasses) should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(Type type, bool includeSubclasses)

Parameters

Type	Name	Description
System.Type	type	The System.Type of the instances that should be checked.
System.Boolean	includeSubclasses	Indicates whether instances of subclasses of the specified type should be checked.

Returns

Type	Description
AssertionsDefinition	Returns `this` to allow definition calls to be chained.

Remarks

Calling MemAssertion.MemAssertion.Assert using this AssertionsDefinition will fail if an instance of the provided type (and optionally its subclasses) exists, unless the type is also included in a call to an AllowXXX or MaxXXX method.

note

NoInstances(Type)

Defines that no instances of the provided type should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(Type type)

Parameters

Type	Name	Description
System.Type	type	The System.Type of the instances that should be checked.

Returns

Type	Description
AssertionsDefinition	Returns `this` to allow definition calls to be chained.

Remarks

Calling MemAssertion.MemAssertion.Assert using this AssertionsDefinition will fail if an instance of the provided type exists, unless the type is also included in a call to an AllowXXX or MaxXXX method.

note

NoInstances(String[], Boolean)

Defines that no instances of Types that matches the provided names (and optionally their subclasses) should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(string[] typeNames, bool includeSubclasses)

Parameters

Type	Name	Description
System.String[]	typeNames	An array containing the names of the `Types` that should be checked.
System.Boolean	includeSubclasses	Indicates whether instances of subclasses of the specified types should be checked.

Returns

Type	Description
AssertionsDefinition	Returns `this` to allow definition calls to be chained.

Remarks

note

The name of a Type can end with the wildcard character '*', which allows all types that starts with the specified text to be matched. This can be used to include all types in a namespace (e.g. “System.Windows.Forms.*” will include all types in the System.Windows.Forms namespace).

NoInstances(String[])

Defines that no instances of Types that matches the provided names should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(string[] typeNames)

Parameters

Type	Name	Description
System.String[]	typeNames	An array containing the names of the `Types` that should be checked.

Returns

Type	Description
AssertionsDefinition	Returns `this` to allow definition calls to be chained.

Remarks

note

The name of a Type can end with the wildcard character '*', which allows all types that starts with the specified text to be matched. This can be used to include all types in a namespace (e.g. "System.Windows.Forms.*" will include all types in the System.Windows.Forms namespace).

NoInstances(String, Boolean)

Defines that no instances of the Types that matches the provided name (and optionally its subclasses) should exist when this definition is asserted using MemAssertion.MemAssertion.Assert.

Declaration

public AssertionsDefinition NoInstances(string typeName, bool includeSubclasses)

Parameters

Type	Name	Description
