Change group box text color?
提问by user20493
How do you change the text color of a group box in C#? The "documentation" doesn't even mention this, and Googling hasn't turned up an answer.
如何在 C# 中更改组框的文本颜色？“文档”甚至没有提到这一点，谷歌搜索也没有找到答案。

Use the ForeColorproperty. Sample code:
使用ForeColor物业。示例代码：
using System;
using System.Drawing;
using System.Windows.Forms;
class Test
{
[STAThread]
static void Main(string[] args)
{
Form form = new Form();
GroupBox group = new GroupBox();
group.Text = "Text";
group.ForeColor = Color.Red;
form.Controls.Add(group);
Application.Run(form);
}
}

I'm assuming you are in winforms not in WPF now.
我假设您现在使用的是 winforms 而不是 WPF。
To change the text color of a group box you use ForeColor this changes the font colour in the header text.
要更改组框的文本颜色，请使用 ForeColor 这会更改标题文本中的字体颜色。

If you're referring to the groupbox text itself, then use what Jon Skeet posted. If you're referring to all the subsequent controls in the groupbox, then you can use this code:
如果您指的是 groupbox 文本本身，请使用 Jon Skeet 发布的内容。如果您指的是 groupbox 中的所有后续控件，则可以使用以下代码：
foreach (Control c in this.groupBox1.Controls)
{
c.ForeColor = this.groupBox1.ForeColor; //or whatever color you want
}

Actually all the answers posted here changes the forecolor of other controls like button, label etc residing inside the groupbox. To specifically change just the text colour of the groupbox there is a simple workaround.
实际上，此处发布的所有答案都会更改位于 groupbox 内的其他控件（如按钮、标签等）的前景色。要专门更改 groupbox 的文本颜色，有一个简单的解决方法。
private void button1_Click(object sender, EventArgs e)
{
List<Color> lstColour = new List<Color>();
foreach (Control c in groupBox1.Controls)
lstColour.Add(c.ForeColor);
groupBox1.ForeColor = Color.Red; //the colour you prefer for the text
int index = 0;
foreach (Control c in groupBox1.Controls)
{
c.ForeColor = lstColour[index];
index++;
}
}
Of course the above code can be meaningless if you are adding controls programmatically later to the groupbox, but the good thing is you can handle all that situations by adding extra conditions in code. To be doubly sure, a list of keyvaluepair of control and forecolor can be employed.
当然，如果您稍后以编程方式向 groupbox 添加控件，则上述代码可能毫无意义，但好处是您可以通过在代码中添加额外条件来处理所有这些情况。可以肯定的是，可以使用控件和前景色的键值对列表。

Or I have changed your code a bit so user can choose between 2 types of color for groupBox only:
或者我对您的代码进行了一些更改，以便用户只能在 groupBox 的两种颜色之间进行选择：
private void SettingGroupBoxColor(bool bSelected)
{
if (!bSelected)
groupBox1.ForeColor = Color.Red;
else
groupBox1.ForeColor = Color.Green;
foreach (Control c in this.groupBox1.Controls)
{
c.ForeColor = Color.Black;
}
}
Passing "true" or "false" values to the upper mehod, will change the groupBox ForeColor only - while all other controls forecolor will remain default (black).
将“true”或“false”值传递给上层方法，只会更改 groupBox ForeColor - 而所有其他控件的前景色将保持默认（黑色）。
