C#更新usercontrol库将删除内部内容
我有一个非常讨厌的问题 在我的用户控件库中，我有一个控件，里面有一个面板，可以容纳内容。 如果我构建这个dll并将它引用到一个项目中，我通常可以使用这个控件并向它添加内容。 现在的问题是：每当我构建此控件库的新版本并更新/覆盖我使用此dll的项目中的dll时，将重新生成包含内容的控件，而现在内容将被删除。 如何解决这个问题C#更新usercontrol库将删除内部内容,c#,user-controls,panel,rebuild,C#,User Controls,Panel,Rebuild,我有一个非常讨厌的问题 在我的用户控件库中，我有一个控件，里面有一个面板，可以容纳内容。 如果我构建这个dll并将它引用到一个项目中，我通常可以使用这个控件并向它添加内容。 现在的问题是：每当我构建此控件库的新版本并更新/覆盖我使用此dll的项目中的dll时，将重新生成包含内容的控件，而现在内容将被删除。 如何解决这个问题 致意 斯文·科尼格 编辑1 注意：我指的面板是一个用户控件，它有一个Windows.Forms.panel来存储内容。 此用户控件的设计器是“ParentControlDe
致意 斯文·科尼格 编辑1
注意：我指的面板是一个用户控件，它有一个Windows.Forms.panel来存储内容。 此用户控件的设计器是“ParentControlDesigner” 编辑2
抱歉，要保存到内容的控件直接保存到通过ParentControlDesigner设计的用户控件。 我之所以这样做是因为如果我使用Windows.Forms.Panel，我在设计时有调整大小的选项。这是我不想要的 编辑3
下面是GroupBox的代码，其中的内容控件位于

这是我的代码更新。
更改：
-现在使用标准Windows.Forms.Panel作为控制容器
-为了避免调整大小或移动，我为事件“Resize”和“LocationChanged”编写了代码
