本文介绍如何在F#编程语言中获取数组特定元素的内存地址。通过使用System.Runtime.InteropServices.Marshal类的方法UnsafeAddrOfPinnedArrayElement，可以得到指定数组元素的原生指针，并进一步将其转换为intptr类型。

It's not convenient to get the memory address of object in F#, and the following code will illustrate how to get the memory of given index item of an array:

//Define your array
let arr = [|1;23|]
//Get the nativeint of arr.[0]
let nativeint = System.Runtime.InteropServices.Marshal.UnsafeAddrOfPinnedArrayElement(arr,0)
//Construct a intptr using the nativeptr<unit> 
let intptr = new System.IntPtr(nativeint.ToPointer())
