webservice里的byte和ATLSOAP_BLOB

c#写的webservice，传入的类型是byte[]。

c++调用webservice，自动产生的WebReference.h里定义的对应类型是ATLSOAP_BLOB，在atlsoap.h里ATLSOAP_BLOB的定义是

[ export ]
typedef struct _tagATLSOAP_BLOB
{
 unsigned long size;
 unsigned char *data;
} ATLSOAP_BLOB;

 

 

如何使用？

例：

//准备byte
unsigned long destLen = ？;

byte* dest = new byte[destLen];

...

 

//byte转ATLSOAP_BLOB

ATLSOAP_BLOB blobIn;
blobIn.size  = destLen;
blobIn.data  = (unsigned char*)malloc(blobIn.size*sizeof((char*)dest));
ATLASSERT(blobIn.data != NULL);
memset(blobIn.data, 0xFF, blobIn.size);
memcpy(blobIn.data, dest, destLen);

...

 

//用完释放blobIn.data

free(blobIn.data);
