How to make a method that will get text content and colors to add text with colors to richTextBox co-CodePudding

Instead typing this in many places in the code :

TextRange rangeOfText1 = new TextRange(RichTextBoxLogger.Document.ContentEnd, RichTextBoxLogger.Document.ContentEnd);
rangeOfText1.Text = "Test";
rangeOfText1.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Yellow);
rangeOfText1.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);

I tried to create a method that i will be able to use all along the code in many places :

private void RichTextBoxAddText(string TextContent, Brushes ForeGroundColor, FontWeights FontWeightType)
        {
            TextRange rangeOfText1 = new TextRange(RichTextBoxLogger.Document.ContentEnd, RichTextBoxLogger.Document.ContentEnd);
            rangeOfText1.Text = "Test";
            rangeOfText1.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Yellow);
            rangeOfText1.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);
        }

but i'm not sure if i'm using the right way with getting the Brushes and the FontWeights the second problem is that i'm getting error :

CS0721 'FontWeights': static types cannot be used as parameters

CodePudding user response：

Define an extension method:

public static class TextRangeExt
{
    public static void RichTextBoxAddText(this TextRange range, string text, 
        SolidColorBrush foregroundColor, 
        FontWeight fontWeight)
    {
        range.Text = text;
        range.ApplyPropertyValue(TextElement.ForegroundProperty, foregroundColor);
        range.ApplyPropertyValue(TextElement.FontWeightProperty, fontWeight);
    }
}

And now you can use the method like:

var doc = RichTextBoxLogger.Document;
new TextRange(doc.ContentEnd, doc.ContentEnd).RichTextBoxAddText("Test", Brushes.Red, FontWeights.Bold);
