C# Beginner, trying to change a fixed background color of a form with text in a textbox-CodePudding

I am a total beginner with c#, i am learning with Udemy.

I have done just a little start but now i want to test for my own.

i have learned how to use a button to change the background color of a form.

BackColor = Color.Red; etc.

I am now trying to make a textbox where i can write in for example Red, Blue, Green ect and the click a button, then the form will change to that color. I want to have fixed colors i can choose from so i am guessing i need to make fixed colors in the formload "tab"?

private void FrmColorCalculator_Load(object sender, EventArgs e)
 
            
            Color red = Color.Red;
            Color green = Color.Green;

should this be in formload? how to make fixed colors? i get an errormessages saying "cannot convert system.drawing.color to string, but thats not what i want to do, i want the color to change.

If someone would be willing to kick me in the right direction?

Use Color.FromName like this:

private void button1_Click_2(object sender, EventArgs e)
{
    try
    {
        this.BackColor = Color.FromName(textBox1.Text);
    }
    catch (Exception ex)
    {
        MessageBox.Show("Invalid color: "   textBox1.Text);
    }            
}

if you want to change form color you can do this by editing the property BackColor,

Form form1= new Form();

private void FrmColorCalculator_Load(object sender, EventArgs e){

     form1.BackColor = Color.Red;
}

f you mean a WPF Window you can use the Background property. From within the Window's code:

Background = Brushes.LightPink;
