Type.IsPrimitive Property

Gets a value indicating whether the Type is one of the primitive types.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

'Declaration
Public ReadOnly Property IsPrimitive As Boolean
'Usage
Dim instance As Type
Dim value As Boolean

value = instance.IsPrimitive

/** @property */
public final boolean get_IsPrimitive ()

public final function get IsPrimitive () : boolean

Not applicable.

Property Value

true if the Type is one of the primitive types; otherwise, false.

The primitive types are Boolean, Byte, SByte, Int16, UInt16, Int32, UInt32, Int64, UInt64, IntPtr, Char, Double, and Single.

If the current Type represents a generic type, or a type parameter in the definition of a generic type or generic method, this property always returns false.

The following example demonstrates the IsContextful, IsMarshalByRef, and IsPrimitive properties of the Type class. It checks whether the given type can be hosted in the context, whether it can be marshaled by reference, and whether the type is a primitive data type.
