During the interview, I was asked how to go through all the colors and names under System.drawing.Color to check.
View Code
public partial class Form1 : Form
{
FlowLayoutPanel newPanel = new FlowLayoutPanel();
public Form1()
{
InitializeComponent();
newPanel.AutoScroll = true;
//newPanel.FlowDirection = FlowDirection.BottomUp;
//newPanel.WrapContents = false;
newPanel.Dock = DockStyle.Fill;
newPanel.BackColor = Color.White;
button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);
}
private void button1_Click(object sender, EventArgs e)
{
newPanel.Controls.Clear();
int i = 1;
foreach (var item in typeof(Color).GetMembers())
{
if (item.MemberType == System.Reflection.MemberTypes.Property && System.Drawing.Color.FromName(item.Name).IsKnownColor == true)// Takes only the property and is known in the property Color , eliminate byte Properties, and 1 Some Boolean properties, etc. ( A B G R IsKnownColor Name Etc.)
{
Label myLable = new Label();
myLable.AutoSize = true;
myLable.BackColor = System.Drawing.Color.FromName(item.Name);
myLable.Text = System.Drawing.Color.FromName(item.Name).Name;
newPanel.Controls.Add(myLable);
//newPanel.GetFlowBreak(myLable);
i++;
}
}
this.Controls.Add(newPanel);
button1.Text = i.ToString();
}
}
