I'm trying to convert a stringto a SolidColorBrushin C#. The code I'm using is:

我试图将转换stringSolidColorBrushC#中。我使用的代码是:

arrColors[arrColors.Length - 1] = 
                         (SolidColorBrush)new BrushConverter().ConvertFromString(sLine);

where sLine is a string read from a text file. For example, sLinemight be "Black".

其中 sLine 是从文本文件中读取的字符串。例如,sLine可能是“黑色”。

This code gives me a FormatException.

这段代码给了我一个FormatException.

Assuming all of your brushes are solid colours, you could construct a Color from a string as follows:

假设你所有的画笔都是纯色的,你可以从一个字符串构造一个颜色,如下所示:

Color color = (Color)ColorConverter.ConvertFromString(sLine);

Then you could create a SolidColorBrushfrom that colour, like so:

然后你可以SolidColorBrush从那个颜色创建一个,像这样:

SolidColorBrush brush = new SolidColorBrush(color);

EDIT: If the string being converted is English but the current culture is not, you may need to use ConvertFromInvariantStringinstead, like so:

编辑:如果被转换的字符串是英语但当前的文化不是,你可能需要使用ConvertFromInvariantString代替,像这样:

ColorConverter converter = new ColorConverter();
Color color = (Color)converter.ConvertFromInvariantString(sLine);

Try this:

尝试这个:

var color = (Color)ColorConverter.ConvertFromString(sLine);
var brush = new SolidColorBrush(color);
