C# ImageFormat to string

Question

How can I obtain human readable string(i.e. image format itself) from System.Drawing.ImageFormat object?

I mean if I have ImageF

Answer 1

ImageFormat values are identified by Guid you need to create your own map of Guid -> Name

var dict = (
    from t in typeof(ImageFormat).GetProperties()
    where t.PropertyType == typeof(ImageFormat)
    let v = (ImageFormat)t.GetValue(null, new object[0])
    select new { v.Guid, t.Name }
    ).ToDictionary(g => g.Guid, g => g.Name);

string name;
if (dict.TryGetValue(ImageFormat.Png.Guid, out name))
{
    Console.WriteLine(name);
}
