Here is my C# code:       public struct DataStruct       {             public string dataName;             public int slot;             public int quad;             public DataStruct(string name, int slot, int quadrant)             {                   this.dataName= name;                   this.slot = slot;                   this.quad = quadrant;             }       } // C++ function [DllImport("CppCode.dll")] public static extern int GetDataList([In, Out] DataStruct[] dataList); // Create the struct array DataStruct[] dataList = new DataStruct[512]; // Call C++ function GetDataList(dataList); C++ code in CppCode.dll: struct DataStruct {      char * dataName;      int slot;      int quad; }; DLLEXPORT int GetDataList(DataStruct* dataList) {       for (int i = 0; i < 100; i++)       {             dataList[i].dataName = "qqq";             dataList[i].slot = i;             dataList[i].quad = i+1;       }       return 0; } Please help to find out if I did something wrong. The most strange thing is that this code works fine in some computers but in other computers, it crashes when return back from C++ code. Thanks a lot!! Re: Pass a struct array to C++ to get data KarstenK2-Dec-09 4:40 KarstenK 2-Dec-09 4:40  you should transfer strings between C# and C++. Use a char[]. Quick rule: use native data types for interfaces. (Use them everywhere erverytime and forever) Never ever use objects or class types. Press F1 for help or google it.

Also the pointer will no longer be valid on return to the C# code. You need to provide a character array (Unicode) and the C++ code will need to copy the text into the array. Re: Pass a struct array to C++ to get data songll2-Dec-09 6:05 songll 2-Dec-09 6:05  Thanks, Richard, Can you give me a detail example on how to copy this?

You need to modify your C# structure to contain only basic types that will map directly to C++ types. You can then use the wcscpy_s[^] function to copy text into the structure.
