You need to use a RichTextBox.
您需要使用RichTextBox。
You can then change the textcolor by selecting text and changing the selection color or font.
然后，您可以通过选择文本并更改选择颜色或字体来更改文本颜色。
richTextBox1.SelectionFont = new Font("Verdana", 12, FontStyle.Bold);
richTextBox1.SelectionColor = Color.Red;

Use a RichTextBox for that, here is an extension method by Nathan Baulch
为此使用 RichTextBox，这是 Nathan Baulch 的扩展方法
public static class RichTextBoxExtensions
{
public static void AppendText(this RichTextBox box, string text, Color color)
{
box.SelectionStart = box.TextLength;
box.SelectionLength = 0;
box.SelectionColor = color;
box.AppendText(text);
box.SelectionColor = box.ForeColor;
}
}

First of all, the details + tags you provided are not sufficient - C# doesn't have one specific UI framework, it has a few: WPF, Winforms, ASP.NET, Silverlight.
首先，你提供的细节 + 标签是不够的——C# 没有一个特定的 UI 框架，它有几个：WPF、Winforms、ASP.NET、Silverlight。
Second of all, you can not do this with a regular textbox control in any of the above. You will need to find/create a custom UI control which has a different behaviour or use a more advanced control e.g. a rich text box.
其次，您不能使用上述任何一种中的常规文本框控件来执行此操作。您将需要查找/创建具有不同行为的自定义 UI 控件或使用更高级的控件，例如富文本框。

Here is an example with a Fontdialog and Colordialog.
这是一个带有 Fontdialog 和 Colordialog 的示例。
void TextfarbeToolStripMenuItemClick(object sender, EventArgs e)
{
colorDialog1.ShowDialog();
richTextBox1.ForeColor = colorDialog1.Color;
listBox1.ForeColor = colorDialog1.Color;
}
void FontsToolStripMenuItemClick(object sender, EventArgs e)
{
fontDialog1.ShowDialog();
richTextBox1.Font = fontDialog1.Font;
listBox1.Font = fontDialog1.Font;
}
void HintergrundfarbeToolStripMenuItemClick(object sender, EventArgs e)
{
colorDialog1.ShowDialog();
richTextBox1.BackColor = colorDialog1.Color;
listBox1.BackColor = colorDialog1.Color;
}
