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)

protected abstract bool IsPrimitiveImpl()

Return Value

Type: System.Boolean
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.

using System;
using System.Reflection;
public class MyTypeDelegatorClass : TypeDelegator
{
    public string myElementType = null;
    private Type myType = null ; 
    public MyTypeDelegatorClass(Type myType) : base(myType)
    {
        this.myType = myType;
    }
    // Override the IsPrimitiveImpl. 
    protected override bool IsPrimitiveImpl()
    {
        // Determine whether the type is a primitive type. 
        if(myType.IsPrimitive)
        { 
            myElementType = "primitive";
            return true;
        }
        return false;
    }
}
public class MyTypeDemoClass
{
    public static void Main()
    {
        try
        {
            Console.WriteLine ("Determine whether int is a primitive type.");
            MyTypeDelegatorClass myType;
            myType = new MyTypeDelegatorClass(typeof(int));
            // Determine whether int is a primitive type. 
            if( myType.IsPrimitive)
            {
                Console.WriteLine(typeof(int) + " is a primitive type.");
            }
            else
            {
                Console.WriteLine(typeof(int) + " is not a primitive type.");
            }
            Console.WriteLine ("\nDetermine whether string is a primitive type.");
            myType = new MyTypeDelegatorClass(typeof(string));
            // Determine if string is a primitive type. 
            if( myType.IsPrimitive)
            {
                Console.WriteLine(typeof(string) + " is a primitive type.");
            }
            else
            {
                Console.WriteLine(typeof(string) + " is not a primitive type.");
            }
        }
        catch( Exception e )
        {
            Console.WriteLine("Exception: {0}", e.Message);
        }
    }
