Constructors

	Name	Description
	IntPtr(Int32)	Initializes a new instance of IntPtr using the specified 32-bit pointer or handle.
	IntPtr(Int64)	Initializes a new instance of IntPtr using the specified 64-bit pointer.
	IntPtr(Void*)	Initializes a new instance of IntPtr using the specified pointer to an unspecified type.

Methods

	Name	Description
	Equals	Returns a value indicating whether this instance is equal to a specified object. (Overrides ValueType.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToInt32	Converts the value of this instance to a 32-bit signed integer.
	ToInt64	Converts the value of this instance to a 64-bit signed integer.
	ToPointer	Converts the value of this instance to a pointer to an unspecified type.
	ToString	Converts the numeric value of the current IntPtr object to its equivalent string representation. (Overrides ValueType.ToString().)

Operators

	Name	Description
	Equality	Determines whether two specified instances of IntPtr are equal.
	Explicit(Int32 to IntPtr)	Converts the value of a 32-bit signed integer to an IntPtr.
	Explicit(Int64 to IntPtr)	Converts the value of a 64-bit signed integer to an IntPtr.
	Explicit(IntPtr to Void*)	Converts the value of the specified IntPtr to a pointer to an unspecified type.
	Explicit(IntPtr to Int64)	Converts the value of the specified IntPtr to a 64-bit signed integer.
	Explicit(IntPtr to Int32)	Converts the value of the specified IntPtr to a 32-bit signed integer.
	Explicit(Void* to IntPtr)	Converts the specified pointer to an unspecified type to an IntPtr.
	Inequality	Determines whether two specified instances of IntPtr are not equal.

Fields

	Name	Description
	Zero	A read-only field that represents a pointer or handle that has been initialized to zero.

Remarks

The IntPtr type is designed to be an integer whose size is platform-specific. That is, an instance of this type is expected to be 32-bits on 32-bit hardware and operating systems, and 64-bits on 64-bit hardware and operating systems.

The IntPtr type can be used by languages that support pointers, and as a common means of referring to data between languages that do and do not support pointers.

IntPtr objects can also be used to hold handles. For example, instances of IntPtr are used extensively in the System.IO.FileStream class to hold file handles.

The IntPtr type is CLS-compliant, while the UIntPtr type is not. Only the IntPtr type is used in the common language runtime. The UIntPtr type is provided mostly to maintain architectural symmetry with the IntPtr type.
