Determines whether the current type can be assigned to a variable of the specified targetType.

public:
 bool IsAssignableTo(Type ^ targetType);
public bool IsAssignableTo (Type? targetType);
member this.IsAssignableTo : Type -> bool
Public Function IsAssignableTo (targetType As Type) As Boolean

Parameters

targetType
Type

The type to compare with the current type.

Returns

Boolean

true if any of the following conditions is true:

  • The current instance and targetType represent the same type.

  • The current type is derived either directly or indirectly from targetType. The current type is derived directly from targetType if it inherits from targetType; the current type is derived indirectly from targetType if it inherits from a succession of one or more classes that inherit from targetType.

  • targetType is an interface that the current type implements.

  • The current type is a generic type parameter, and targetType represents one of the constraints of the current type.

  • The current type represents a value type, and targetType represents Nullable<c> (Nullable(Of c) in Visual Basic).

false if none of these conditions are true, or if targetType is null.
