以粗体显示我收到此错误
'InjectIcon'不是'System.Windows.Forms.Button'的成员。
它与基础知识无关，因为我用谷歌搜索它：PP.s。
按钮2的名称是IconInjector
错误在这一行
如果cb2.Checked然后IconInjector.InjectIcon（sfd.FileName，iconPath）
答案 0 :(得分：1)
在谷歌的帮助下，我找到了similar code。我想你想要改变可执行文件的图标/资源。这对初学者来说不是正确的主题，你不会学到任何东西，并且依赖于给你源代码的人。
您的代码缺少IconInjector类及其函数InjectIcon。不确定这是否有效，但看看自己（控件名称更改为更有意义）：
