c# – 如何在win表单项目中创建用户控件的dll？

我在我的项目中创建了这个用户控件.
当我编译项目时,我看到项目DLL.
但是,当我编译项目时,我怎么能创建它还会创建一个用户控件的DLL,所以稍后在其他项目上我将能够将此用户控件dll添加到我的工具箱？

                    return;

                m_itemIndexes.Remove(index);
                DrawItem(index);
            }
        }
    }
}

解决方法

您将需要创建一个单独的项目类型 Windows Forms Control Library添加您的UserControls.它的输出是Type Class Library.编译完成后,可以通过右键单击并选择“选择项目”并浏览到dll的位置将其添加到ToolBox中.
