I think you mean all controls on the form.
So simply you can use Controlsproperty inside your form object.
我认为您的意思是表单上的所有控件。因此，您可以Controls在表单对象中使用属性。
foreach(Control c in this.Controls)
{
//TODO:
}

Try this method in your form. It will recursively get all controls on your form, and their children:
在您的表单中尝试此方法。它将递归地获取您的表单及其子项上的所有控件：
public static List<Control> GetControls(Control form)
{
var controlList = new List<Control>();
foreach (Control childControl in form.Controls)
{
// Recurse child controls.
controlList.AddRange(GetControls(childControl));
controlList.Add(childControl);
}
return controlList;
}
Then call it with a:
然后用一个调用它：
List<Control> availControls = GetControls(this);

Or, ProfK's solution in enumerable syntax:
或者，ProfK 的可枚举语法解决方案：
public static IEnumerable<Control> GetControls(Control form) {
foreach (Control childControl in form.Controls) { // Recurse child controls.
foreach (Control grandChild in GetControls(childControl)) {
yield return grandChild;
}
yield return childControl;
}
}
