你如下试试看：

void __fastcall TForm1::Button1Click(TObject *Sender)
{
TCanvas *canvas;
Graphics::TBitmap *bmp;
try
{
canvas = new TCanvas();
canvas->Handle = GetDC(0);
bmp = new Graphics::TBitmap();
bmp->Width = Screen->Width;
bmp->Height = Screen->Height;
TRect rect = Rect(0,0,Screen->Width,Screen->Height);
bmp->Canvas->CopyRect(rect,canvas,rect);
bmp->SaveToFile("c:\\zbc.bmp");
}
__finally
{
delete canvas;
delete bmp;
}
}
