如何更改 TextBox 的背景颜色？

If it's WPF, there is a collection of colors in the static class Brushes.
如果是WPF，静态类中有颜色的集合Brushes。
TextBox.Background = Brushes.Red;
Of course, you can create your own brush if you want.
当然，您可以根据需要创建自己的画笔。
LinearGradientBrush myBrush = new LinearGradientBrush();
myBrush.GradientStops.Add(new GradientStop(Colors.Yellow, 0.0));
myBrush.GradientStops.Add(new GradientStop(Colors.Orange, 0.5));
myBrush.GradientStops.Add(new GradientStop(Colors.Red, 1.0));
TextBox.Background = myBrush;

It is txtName.BackColor = System.Drawing.Color.Red;
这是 txtName.BackColor = System.Drawing.Color.Red;
one can also use txtName.BackColor = Color.Aqua;which is the same as txtName.BackColor = System.Color.Aqua;
一个也可以使用txtName.BackColor = Color.Aqua;这是相同的txtName.BackColor = System.Color.Aqua;
Only Problem with System.color is that it does not contain a definition for some basic colors especially white, which is important cause usually textboxes are white;
System.color 的唯一问题是它没有包含一些基本颜色的定义，尤其是白色，这很重要，因为通常文本框是白色的；

Setting textbox backgroundcolor with multiple colors on single click.
单击即可设置多种颜色的文本框背景颜色。
Note:- using HTML and Javscript.
注意：- 使用 HTML 和 JavaScript。
< input id="ClickMe_btn" onclick="setInterval(function () { ab() }, 3000);" type="button" value="ClickMe" />
< input id="ClickMe_btn" onclick=" setInterval(function () { ab() }, 3000);" type="button" value="ClickMe" />
var arr, i = 0; arr = ["Red", "Blue", "Green", " Orange ", "Purple", "Yellow", "Brown", "Lime", "Grey"]; // We provide array as input.
var arr, i = 0; arr = [“红色”、“蓝色”、“绿色”、“橙色”、“紫色”、“黄色”、“棕色”、“石灰”、“灰色”]; // 我们提供数组作为输入。
function ab()
{ document.getElementById("Text").style.backgroundColor = arr[i];
window.alert(arr[i]);
i++;
}
Note: You can change milliseconds, with setInterval 2nd parameter.
注意：您可以使用 setInterval 第二个参数更改毫秒。
