您可以在当前项目中添加参考到其他项目;只需引用.exe或.dll（如果它是类库）。



（是的; .exe可以像.dll一样访问。因为访问的表单/窗口/类是公开的。

You can add a "reference" in your current project to the "other" project; just reference the .exe or the .dll (if it's a class library).

(Yes; an .exe can be accessed as you would a .dll as long as the accessed form / window / class is public).
