Consider my windows application built using C# VS 2005 displays certain contents in a multi lined text box. Now when i add some new text, it should appear in a different colour. i.e i need to differentiate the text which gets displayed when my project is run and the text that i enter in the text box. how can i do this.?

推荐答案

普通 TextBox 控件不支持多种颜色、字体等.

The plain TextBox control doesn't support multiple colours, fonts etc.

我怀疑您需要使用 RichTextBox 代替.然后您可以设置 SelectionColor 属性来改变当前选中文本或插入到当前插入点的文本的颜色.

I suspect you'll need to use a RichTextBox instead. You can then set the SelectionColor property to change the colour of the currently selected text or text inserted at the current insertion point.

我应该补充一点，经过几次快速实验后，我发现设置选择颜色然后立即以编程方式附加文本并不像我希望的那么简单.也许另一个答案会解释原因:) 但是，用户输入的文本肯定会立即以新颜色显示...

I should add that after a few quick experiments, I've found that setting the selection colour and then immediately appending text programmatically doesn't work quite as straightforwardly as I'd hoped. Maybe another answer will explain why :) However, text entered by the user certainly appears in the new colour immediately...
