推荐答案

public Color GetColorFromText(string colorString)
        {
            Type colorType = (typeof(System.Windows.Media.Colors));
            if (colorType.GetProperty(colorString) != null)
            {
                object colour = colorType.InvokeMember(colorString, BindingFlags.GetProperty, null, null, null);
                if (colour != null) ;
                {
                    return (Color)colour;
                }
            }
            return Color.FromRgb(255,255,255);
        }

那么你可以这样称呼

then you can call it like this

this.comboBox1.Background = new SolidColorBrush(GetColorFromText("Blue"));

希望这对您有帮助

Hope this helps

<ComboBox Height="23"

          Name="comboBox1"

          Background="{Binding Path=SelectedItem, RelativeSource={RelativeSource Self}}"/>

使用SelectedItem 属性，并将RelativeSource设置为self(其组合框为"combobox1").如果您想从另一个组合框设置背景，只需执行以下绑定即可:{Binding Path=SelectedItem, ElementName=comboBox2}
是不是很简单！

Use the SelectedItem property with the RelativeSource set as self(its the same combobox "combobox1"). Had it been the case where you wanted to set the background from another combobox, just do this binding: {Binding Path=SelectedItem, ElementName=comboBox2}
Simple isn''t it!
