How to set Border.BorderBrush from string

Theres a problem. I can't set value of BorderBrush fros C#-code (not in XAML):

 ((Border)((Image)sender).Parent).BorderBrush = "#FFBCC7D8";

How to solve this problem?

From stackoverflow

• You must use an Converter to convert the string to a Brush-Object. In the Framework there is a BrushConverter to do this.

  BrushConverter converter = new BrushConverter();
  ((Border)((Image)sender).Parent).BorderBrush = converter.ConvertFromString("#FFBCC7D8") as Brush;
