C# 怎么封装含有指针的结构体

[youqingyike]

结构体里面含有 char*，int*，char[],int[],
比如：C 或C++ 动态库中，函数接口参数如下，
全是输入参数，
typedef struct MyStruct
{
char* pChar;
int* pInt;
char arrChar[20];
int arrInt[10];
}

C# 中如何封装对应结构体，求指教，主要是char* pChar 和 int* pInt 怎么获取地址

string和int[]吧。 看看这篇讨论: http://stackoverflow.com/questions/11968960/how-use-pinvoke-for-c-struct-array-pointer-to-c-sharp

typedef struct MyStruct { char* pChar; int* pInt; char arrChar[20]; int arrInt[10]; } [StructLayout(LayoutKind.Sequential)] public unsafe struct MyStruct{ public char* pChar; char* pChar; int* pInt; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)] string arrChar; [MarshalAs(UnmanagedType.ByValArray, SizeConst = 10)] int[] arrInt; }

谢谢，我看下

C的Dll 结构体定义如下： typedef struct structPointer { void* pvVoid; bool* pBool; char* pChar; int* pInt; short* pShort; long* lpLong; unsigned char* pucChar; unsigned int* puiInt; unsigned short* pusShort; unsigned long* pulLong; float* pFloat; double* pDouble; }stPointer,*pstPointer; C# 中对应结构体定义如下： [StructLayout(LayoutKind.Sequential)] public struct stPointer { [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pvVoid; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pBool; public string pChar; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pInt; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pShort; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr lpLong; public string pucChar; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr puiInt; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pusShort; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pulLong; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pFloat; [MarshalAs(UnmanagedType.SysUInt)] public IntPtr pDouble; }; C中函数 ： _declspec(dllexport) void pointStruct(stPointer stTest); C#中对应定义： [DllImport("DataTypeTest_Dll.dll", EntryPoint = "pointStruct")] public static extern void pointStruct(stPointer stTest); 调用后，地址传值是正确，除字符串 public string pChar; 和 public string pucChar; 正确， 其他值都不对，有的是非常大的负值，不知什么原因
