Windows窗体：在源代码中设置窗口图标（不使用设计器工具）

Question

I wrote a Windows Form from scratch, only in C# code, not using Visual Studio's form editor.

Now I want to set an icon to the window, so I added the myapp.ico file as a resource and wrote in the Form's constructor:

var resources = new System.ComponentModel.ComponentResourceManager(typeof(MyForm));
Icon = ((System.Drawing.Icon)(resources.GetObject("myapp.Icon")));

I also set myapp.ico in the project's Properties>Application>Icon and manifest>Icon.

But the icon is not displayed, I get the default 3 squares icon:

Answer 1

Loading the icon from resources like this fixed the issue:

Icon = ((System.Drawing.Icon)(Properties.Resources.myapp));

(You first need to add the myapp.ico file as a resource to the project)

I am open to any better solution.
