.NET 相当于 size_t [英] .NET equivalent of size_t

问题描述

我有一段 .NET 代码，我想将其移植到 64 位.这些代码基本上是对其他一些 C dll 的一组 P/Invoke 调用.C dll 中的函数之一具有参数size_t".我应该在我的 P/Invoke 签名中使用什么数据类型，以便编组工作正常.我正在考虑使用 IntPtr 或 UIntPtr 但有人说它们是 .NET 中的指针等价物，不应该使用它.有谁知道这个的正确类型是什么?

I have a piece of .NET code which I want to port to 64-bit. The codes basically is a set of P/Invoke calls to some other C dll. One of the functions in the C dll has a parameter 'size_t'. What datatype should I use in my P/Invoke signature so that the marshalling works fine. I was thinking of using a IntPtr or a UIntPtr but some say that they are a pointer equivalent thing in .NET and shouldnt be using it. Does anyone know what the correct type for this is?

推荐答案

UIntPtr 会起作用(IntPtr 可能也会起作用，但 size_t 是无符号的，所以 UIntPtr 更适合)

UIntPtr will work (IntPtr would probably work too, but size_t is unsigned, so UIntPtr is a better fit)
