Type.IsPrimitive Property

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

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

public bool IsPrimitive { get; }

Property Value

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

Implements

_Type.IsPrimitive

The primitive types are Boolean, Byte, SByte, Int16, UInt16, Int32, UInt32, Int64, UInt64, IntPtr, UIntPtr, 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.

using System;
using System.Runtime.Remoting.Contexts;
public class MyContextBoundClass: ContextBoundObject
{
    public string myString = "This class demonstrates the IsContextful, IsMarshalByRef, and IsPrimitive properties.";
}
public class MyTypeDemoClass
{
    public static void Main()
    {
        try
        {
            // Determine whether the types can be hosted in a Context.
            Console.WriteLine ("The IsContextful property for the {0} type is {1}.", typeof(MyTypeDemoClass).Name, typeof(MyTypeDemoClass).IsContextful);
            Console.WriteLine ("The IsContextful property for the {0} type is {1}.", typeof(MyContextBoundClass).Name, typeof(MyContextBoundClass).IsContextful);

            // Determine whether the types are marshalled by reference.
            Console.WriteLine ("The MarshalByRef property of {0} is {1}.", typeof(MyTypeDemoClass).Name, typeof(MyTypeDemoClass).IsMarshalByRef);
            Console.WriteLine ("The MarshalByRef property of {0} is {1}.", typeof(MyContextBoundClass).Name, typeof(MyContextBoundClass).IsMarshalByRef);

            // Determine whether the types are primitive datatypes.
            Console.WriteLine ("Is {0} is a primitive data type? {1}.", typeof(int).Name, typeof(int).IsPrimitive);
            Console.WriteLine ("Is {0} a primitive data type? {1}.", typeof(string).Name, typeof(string).IsPrimitive);
        } 
        catch (Exception e)
        {
            Console.WriteLine("An exception occurred: " + e.Message);
        }
    }
}
