This is the value type used to store unmanaged pointers or handles (e.g., IntPtr objects are used in the System.IO.FileStream class to hold file handles).

Using this type allows your pointers to be platform-independent, as IntPtr is automatically mapped to a 32-bit integer on 32-bit operating systems and to a 64-bit integer on 64-bit operating systems. The IntPtr type is CLS-compliant and should be used in preference of the UIntPtr.

public struct IntPtr : System.Runtime.Serialization.ISerializable {
// Public Constructors
   public IntPtr(int value);
   public IntPtr(long value);
   public IntPtr(void *value);
// Public Static Fields
   public static readonly IntPtr Zero;   
// =0
// Public Static Properties
   public static int Size{get; }
// Public Static Methods
   public static bool operator !=(IntPtr value1, IntPtr value2);
   public static bool operator =  =(IntPtr value1,  IntPtr value2);
   public static explicit operator int(IntPtr value);
   public static explicit operator long(IntPtr value);
   public static explicit operator IntPtr(int value);
   public static explicit operator IntPtr(long value);
   public static explicit operator IntPtr(void *value);
   public static explicit operator Void(IntPtr value);
// Public Instance Methods
   public override bool Equals(object obj);

   public override int GetHashCode( );

   public int ToInt32( );
   public long ToInt64( );
   public void* ToPointer( );
   public override string ToString( );
