逐项选择项目名称

Question

I get all Brushes colors

var colorNames = typeof(Brushes)
                    .GetProperties(BindingFlags.Static | BindingFlags.Public)
                    .Select(x => x.Name);

How can I get color index where color name is "Black"?

Why I can't go this way colorNames.FirstOrDefault(color => color.Name == "Black").Id; ?

Edit: I use colorNames for DropDown data, I need index of certain color to set it as default DropDown value.

Answer 1

Try this to return the index of the color that is Black, use this query:

var colors = typeof(Brushes)
                .GetProperties(BindingFlags.Static | BindingFlags.Public)
                .ToList();

var index = colors.FindIndex(color => color.Name == "Black");

After testing this, I get the value of 8 for the index of the color which is Black
