A question about using GDI+

[AsonJia]

我设置好了环境已经能使用GDI+了,可是为甚么下面这样一个简单的语句,居然会出现那么多的错误,大家指点一下.
Image *pImage=Image::FromStream(pStream,FALSE);

Error:
D:\MyWorkspace\Project\JoyousPage\JPImage.cpp(64) : error C2065: 'Image' : undeclared identifier
D:\MyWorkspace\Project\JoyousPage\JPImage.cpp(64) : error C2065: 'pImage' : undeclared identifier
D:\MyWorkspace\Project\JoyousPage\JPImage.cpp(64) : error C2653: 'Image' : is not a class or namespace name
