Convert OBJECT to System.Drawing.Color

Question

I know there are many ways to convert colors in C#, everything from converting strings to Color values, HTML conversion, and even XNA framework; however, I have a object that returns a type of System.Drawing.Color; but as it's an 'object', and not a 'color', i can't seem to use the normal color commands on it.

public void SetPropertyValue(string propertyName, object value)
    {
        _PropertyValues[propertyName] = value;
        Console.WriteLine("Setting Property: {0}={1}", propertyName, value);
    }

The above is what happens when a user changes a value on the property Grid in C#. The results are below:

Known Names

Setting Property: Color=Color [DimGray]

Custom Color

Setting Property: Color=Color [A=255, R=255, G=255, B=128]

System Color

Setting Property: Color=Color [ControlText]

I would like to take the values it has there, and actually convert it to a color, so that I can have it in a defaultColor variable, which was created previously in the program.

However, as it's an object and not an actual 'System.Drawing.Color', i can't use things like:

.ToKnownColor()

.ToArgb()

.ToName()

and so on.

I know that there has to be a way to convert from the object to an actual color. I do the value.GetType() and it returns System.Drawing.Color , so the system knows it's a color, but for the life of me i can't seem to manipulate it.

I'm not an expert at C# yet, so sorry if this sounds so basic, but i'd still like some help with it.

Answer 1

Cast it to Color :

var effectiveColor = (System.Drawing.Color)value;

This thing in brackets is an explicit cast , where you tell the compiler that you know better and that an actual type of a variable is something else.

Answer 2

The object really is a Color , it's just being referenced by an Object reference. So all you need to do is cast it to a Color.

Color myColor = (Color)value;
// now you can do all color operations on myColor

Answer 3

如果仅此，您应该就可以将object投射为Color ：

Color color = (Color)value;
