C# 添加一个'；标签'；控制到a'；RichTextBox'；

将

标签

控件添加到

RichTextBox

时遇到问题。显然，代码中一定有我遗漏的东西。如果有人能指出我的疏忽，我将不胜感激。我知道两个控件都已创建，但

标签

不显示在

RichTexBox

的顶部……而是在其后面创建的

一般来说，您需要做的就是在标签上添加一个文本值！你应该注意每个控件的x-y坐标

RichTextBox richBox8 = null;
Label label8 = null;
private void button1_Click(object sender, EventArgs e)
{
    richBox8 = new RichTextBox();
    richBox8.Location = new System.Drawing.Point(1, 1);
    richBox8.Size = new System.Drawing.Size(300, 200);
    richBox8.Name = "richTextBox8";
    Controls.Add(richBox8);

    label8 = new Label();
    label8.Location = new System.Drawing.Point(5, 5);
    label8.Name = "label8";
    label8.Size = new System.Drawing.Size(110, 25);
    label8.Text = "hello world";  // crucial, if there is no text, you won't see any label!
    richBox8.Controls.Add(label8);
    // adding the label once again to the form.Controls collection is unnecessary
}

虽然可以将标签添加到

RichTextBox

控件中，但我认为这不是很有用！

RichTextBox

可用于显示和格式化文本：

不同的项目需要不同的任务。我正在试验RichTextBox和标签，因此我需要知道它们是如何协同工作的。谢谢你的回答，非常有帮助。

RichTextBox richBox8 = null;
Label label8 = null;
private void button1_Click(object sender, EventArgs e)
{
    richBox8 = new RichTextBox();
    richBox8.Location = new System.Drawing.Point(1, 1);
    richBox8.Size = new System.Drawing.Size(300, 200);
    richBox8.Name = "richTextBox8";
    Controls.Add(richBox8);

    label8 = new Label();
    label8.Location = new System.Drawing.Point(5, 5);
    label8.Name = "label8";
    label8.Size = new System.Drawing.Size(110, 25);
    label8.Text = "hello world";  // crucial, if there is no text, you won't see any label!
    richBox8.Controls.Add(label8);
    // adding the label once again to the form.Controls collection is unnecessary
}

public Form1()
{
    InitializeComponent();
    richTextBox1.Text = "demo text demo text demo text demo text demo text demo text demo text demo text demo text demo text demo text demo text ";
}

private void button1_Click(object sender, EventArgs e)
{
    richTextBox1.Select(10, 20);
    richTextBox1.SelectionColor = Color.Blue;

    richTextBox1.Select(25, 30);
    richTextBox1.SelectionFont = new Font("Verdana", 12);
}
