将控件的属性名称传递给函数

Question

I have function that changes the property of controls based on the control name and the input command.

 public void SetControl(string ControlName, string Operation)
    {
        Control Control = this.Controls.Find(ControlName, true)[0];

        switch (Operation)
        {
            case "ok":
                Control.BackColor = Color.Green;
                Control.ForeColor = Color.Black;
                break;
            case "error":
                Control.BackColor = Color.Red;
                Control.ForeColor = Color.Blue;
                break;
        }
    }

now I am wondering if there is any way to pass property name as well? of course I can do something like this:

if (propertyname=="ForeColor")
 {Control.ForeColor = Color.Black;}

but then I should do this for all of the properties that I am going to change! Is there anyway to find and change the property based on its name?

Yes. This is precisely what reflection does.

var value = Control.GetType().GetProperty(propertyname).GetValue(Control, null);

Then set your value

Control.GetType().GetProperty(propertyname).SetValue(Control, valueToSet);
