Examples

The following example uses managed pointers to reverse the characters in an array. After it initializes a String object and gets its length, it does the following:

1. Calls the Marshal.StringToHGlobalAnsi method to copy the Unicode string to unmanaged memory as an ANSI (one-byte) character. The method returns an IntPtr object that points to the beginning of the unmanaged string. The Visual Basic example uses this pointer directly; in the C++, F# and C# examples, it is cast to a pointer to a byte.

2. Calls the Marshal.AllocHGlobal method to allocate the same number of bytes as the unmanaged string occupies. The method returns an IntPtr object that points to the beginning of the unmanaged block of memory. The Visual Basic example uses this pointer directly; in the C++, F# and C# examples, it is cast to a pointer to a byte.

3. The Visual Basic example defines a variable named offset that is equal to the length of the ANSI string. It is used to determine the offset into unmanaged memory to which the next character in the ANSI string is copied. Because its starting value is the length of the string, the copy operation will copy a character from the start of the string to the end of the memory block.

   The C#, F# and C++ examples call the ToPointer method to get an unmanaged pointer to the starting address of the string and the unmanaged block of memory, and they add one less than the length of the string to the starting address of the ANSI string. Because the unmanaged string pointer now points to the end of the string, the copy operation will copy a character from the end of the string to the start of the memory block.

4. Uses a loop to copy each character from the string to the unmanaged block of memory.

   The Visual Basic example calls the Marshal.ReadByte(IntPtr, Int32) method to read the byte (or one-byte character) at a specified offset from the managed pointer to the ANSI string. The offset is incremented with each iteration of the loop. It then calls the Marshal.WriteByte(IntPtr, Int32, Byte) method to write the byte to the memory address defined by the starting address of the unmanaged block of memory plus offset. It then decrements offset.

   The C#, F# and C++ examples perform the copy operation, then decrement the pointer to the address of the next location in the unmanaged ANSI string and increment the pointer to the next address in the unmanaged block.

5. All examples call the Marshal.PtrToStringAnsi to convert the unmanaged memory block containing the copied ANSI string to a managed Unicode String object.

6. After displaying the original and reversed strings, all examples call the FreeHGlobal method to free the memory allocated for the unmanaged ANSI string and the unmanaged block of memory.

Remarks

The IntPtr type is designed to be an integer whose size is the same as a pointer. That is, an instance of this type is expected to be 32 bits in a 32-bit process and 64 bits in a 64-bit process.

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.

Note

Using IntPtr as a pointer or a handle is error prone and unsafe. It is simply an integer type that can be used as an interchange format for pointers and handles due to being the same size. Outside of specific interchange requirements, such as for passing data to a language that doesn't support pointers, a correctly typed pointer should be used to represent pointers and SafeHandle should be used to represent handles.

This type implements the ISerializable. In .NET 5 and later versions, this type also implements the IFormattable interfaces. In .NET 7 and later versions, this type also implements the IBinaryInteger<TSelf>, IMinMaxValue<TSelf>, and ISignedNumber<TSelf> interfaces.

In C# starting from version 9.0, you can use the built-in nint type to define native-sized integers. This type is represented by the IntPtr type internally and provides operations and conversions that are appropriate for integer types. For more information, see nint and nuint types.

In C# starting from version 11 and when targeting the .NET 7 or later runtime, nint is an alias for IntPtr in the same way that int is an alias for Int32.
