Type.IsPrimitiveImpl Method

When overridden in a derived class, implements the IsPrimitive property and determines whether the Type is one of the primitive types.

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

'Declaration
Protected MustOverride Function IsPrimitiveImpl As Boolean
'Usage
Dim returnValue As Boolean

returnValue = Me.IsPrimitiveImpl
protected abstract boolean IsPrimitiveImpl ()
protected abstract function IsPrimitiveImpl () : boolean
Not applicable.

Return 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, Char, Double, and Single.

The following example determines whether the given type is a primitive type and displays the result.
