如果在代码后面的wpf中动态添加按钮，如何向它们添加工具提示或将文本添加到实际按钮？
这是你在windows窗体中会做的，但我不认为你可以在wpf中做到这一点：
partial class Window1
{
void button3Click(object sender, RoutedEventArgs e)
{
//toolTip1.SetToolTip(this.button1, "My button1");
MessageBox.Show("action 3");
}
void button2Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("action 2");
}
void button1Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("action 1");
}
public Window1()
{
this.InitializeComponent();
populateButtons();
//ToolTip toolTip1 = new ToolTip();
//// Set up the delays for the ToolTip.
//toolTip1.AutoPopDelay = 5000;
//toolTip1.InitialDelay = 1000;
//toolTip1.ReshowDelay = 500;
//// Force the ToolTip text to be displayed whether or not the form is active.
//toolTip1.ShowAlways = true;
}
public void populateButtons()
{
int xPos;
int yPos;
Random ranNum = new Random();
foreach (var routedEventHandler in new RoutedEventHandler[] { button1Click, button2Click, button3Click })
{
Button foo = new Button();
Style buttonStyle = Window.Resources["CurvedButton"] as Style;
int sizeValue = 100;
foo.Width = sizeValue;
foo.Height = sizeValue;
xPos = ranNum.Next(200);
yPos = ranNum.Next(250);
//canvas1.HorizontalAlignment = HorizontalAlignment.Left;
//canvas1.VerticalAlignment = VerticalAlignment.Top;
//canvas1.Margin = new Thickness(xPos, yPos, 0, 0);
foo.HorizontalAlignment = HorizontalAlignment.Left;
foo.VerticalAlignment = VerticalAlignment.Top;
foo.Margin = new Thickness(xPos, yPos, 0, 0);
foo.Style = buttonStyle;
foo.Click += routedEventHandler;
LayoutRoot.Children.Add(foo);
}
}
}
}
至于添加文字我不确定吗？

您可以将ToolTip分配给ToolTip的{{1}}属性，并将Button属性设置为您要显示的文字：
Content如果你想让按钮显示出来，你必须将它添加到它应该属于的面板 - 我认为它是canavs：
ToolTip t = new ToolTip();
t.Content = "Something helpful";
Button b = new Button;
b.Content = "Hover over me";
b.ToolTip = t;

您是否尝试使用Tooltip - 属性？
