c指针结构为c＃ [英] c pointer in structure to c#

问题描述

你好，

我有这样的交流结构：

typedef struct{
	int batch_normalize;
	int *batch;
}layer;

我将其转换为c＃：

[StructLayout(LayoutKind.Sequential)]
	public struct layer{
		
		public int batch_normalize;
		public int batch;
	}

c函数是：

void Test(int b, int bn){
          layer l;
         l.batch_normalize = bn;
         l.batch = calloc(b, sizeof(int));
}

我需要从dll调用此函数，请我如何解决这个难题。

i need to call this function from dll , please how i can solve this piece of puzzle.

谢谢

推荐答案

指针不等同于int。指针是什么？

A pointer is not equivalent to an int, ever. What is that a pointer to?

[StructLayout(LayoutKind.Sequential)]
public struct layer
{
   public int batch_normalize;
   public IntPtr batch;
}

C函数不能正确。它将积分文字5指定给指针。虽然在旧版本的C ++中是合法的，但在新版本中这是不合适的，因为它没有意义。你不能（很可能）在
5.地址有任何东西。

The C function cannot be right. It is assigning the integral literal 5 to a pointer. While legal in the older versions of C++ this is being deprecated in newer versions because it doesn't make sense. You cannot (most likely) have anything at address 5.
