richtextbox SelectionColor 和 SelectionBackColor 属性

发布于 2024-07-22 05:39:27 字数 361 浏览 3 评论 0原文

我想选择特定的文本行并用蓝色突出显示它，并且我希望该文本的前色为白色。我尝试过

 this.Select(start, length);
 this.SelectionBackColor = Color.Blue;
 this.SelectionColor = Color.White;

，但没有成功。怎么了？我想模拟当我们通过鼠标选择一些文本时得到的效果，它的背景色变为浅蓝色，内部文本变为白色。我可以通过这样做来实现这一点

 this.Select(start, length);

，但是一旦它失去焦点，选择就会消失，我希望它永久存在。

I want to select a particular line of text and highlight it with a Blue Color and i want the forecolor of that text to be white.
I tried

 this.Select(start, length);
 this.SelectionBackColor = Color.Blue;
 this.SelectionColor = Color.White;

but it doesn't work.
What is wrong?
I want to simulate the effect we get when we select some text through the mouse, where it's backcolor gets light blue and text inside gets white. I can get that by just doing

 this.Select(start, length);

but then as soon as it loses focus, the selection vanishes, i want it permanent.

有更简单的方法来为 RichTextBox 中的文本着色：

richtTextBox.SelectionColor = Color.Red;
richTextBox.SelectedText = "Red text";
richtTextBox.SelectionColor = Color.Green;
richTextBox.SelectedText = "Green text";

你会得到：

尝试做这样的事情：

        this.richTextBox1.SelectionStart = start;
        this.richTextBox1.SelectionLength = length;
        this.richTextBox1.SelectionColor = Color.White;
        this.richTextBox1.SelectionBackColor = Color.Blue;

Try doing something like this:

        this.richTextBox1.SelectionStart = start;
        this.richTextBox1.SelectionLength = length;
        this.richTextBox1.SelectionColor = Color.White;
        this.richTextBox1.SelectionBackColor = Color.Blue;
