绘图应用 - 智能感知错误

Question

所以我正在制作一个绘图应用程序，我有一个最后的错误 - intellisense。这是错误：

IntelliSense: no instance of overloaded function "System::Drawing::Graphics::DrawLine" matches the argument list
            argument types are: (System::Drawing::SolidBrush, System::Drawing::Point, System::Drawing::Point)
            object type is: System::Drawing::Graphics

这是代码/行：

g->DrawLine(SolidBrush(colorSel), oldPosition, e->Location);
