设置:
我有一个 COM DLL,它调用托管 C# DLL 中的一个方法。此函数返回一个 C# string[] 数组,该数组被封送为 SAFEARRAY。
问题:
当我尝试访问安全数组中的字符串时,我只得到字符串的第一个字符。我究竟做错了什么?
编码:
// Pointer to the managed interface
DatabasePtr pODB(__uuidof(DBClass));
// Get the string[] array from the managed method
SAFEARRAY* safearray = pODB->GetStringArray();
HRESULT hresult;
long ubound;
long lbound;
hresult = SafeArrayGetUBound(safearray, 1, &ubound);
hresult = SafeArrayGetLBound(safearray, 1, &lbound);
long index;
BSTR fromarray;
for (; lbound <= ubound; lbound++)
{
index = lbound;
hresult = SafeArrayGetElement(safearray, &index, (void*)&fromarray);
char buffer[512];
sprintf_s(buffer,"%s",fromarray);
MessageBox(0, (LPCSTR)buffer, "...", 0);
}
谢谢你的帮助,-
肖恩!
