Type.IsPointer Property

Silverlight

Other Versions

Gets a value indicating whether the Type is a pointer.

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

Syntax

public bool IsPointer { get; }

Property Value

Type: System.Boolean
true if the Type is a pointer; otherwise, false.

Remarks

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.

This property is read-only.

Examples

The following example shows a use of the IsPointer property.


using System;
using System.Reflection;
public class MyTypeDelegator : TypeDelegator
{
   public string myElementType = null;
   private Type myType = null;
   public MyTypeDelegator(Type myType)
      : base(myType)
   {
      this.myType = myType;
   }
   // Override Type.HasElementTypeImpl().
   protected override bool HasElementTypeImpl()
   {
      // Determine whether the type is an array.
      if (myType.IsArray)
      {
         myElementType = "array";
         return true;
      }
      // Determine whether the type is a reference.
      if (myType.IsByRef)
      {
         myElementType = "reference";
         return true;
      }
      // Determine whether the type is a pointer.
      if (myType.IsPointer)
      {
         myElementType = "pointer";
         return true;
      }
      // Return false if the type is not a reference, array, or pointer type.
      return false;
   }
}
