Question

c#做一个按钮，点击它后label显示textbox中输入的内容

private void button1_Click(object sender, RoutedEventArgs e)
{

label3.Text = textBox1.Text;

}

可是有这个问题,label3.Text，Text有问题。是怎么回事呢？

Error 1 'System.Windows.Controls.Label' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Windows.Controls.Label' could be found (are you missing a using directive or an assembly reference?)

Answer 1

楼主用的是wpf吧，wpf的label没有Text属性；
label3.Content = textBox1.Text;

Answer 2

是不是没有这个label,或是名字错了.
