我试图在WPF TextBlock中突出显示或设置一些选定文本的背景。
假设我有2个文本文件,我将它们加载到内存中,完成差异比较,然后想在WPF应用程序中显示。想象一下循环遍历每一行,然后将文本追加到TextBlock并根据删除、插入或相同的文本更改颜色。
for (int i = 0; i < theDiffs.Count; i++)
{
switch (theDiffs[i].operation)
{
case Operation.DELETE:
// set color to red on Source control version TextBlock
break;
case Operation.INSERT:
WorkspaceVersion.AppendText(theDiffs[i].text);
// set the background color (or highlight) of appended text to green
break;
case Operation.EQUAL:
WorkspaceVersion.AppendText(theDiffs[i].text);
// Set the background color (highlight) of appended text to yellow
break;
default:
throw new ArgumentOutOfRangeException();
}
}
