WPF C# 以编程方式添加事件处理程序 [英] WPF C# adding event handler programmatically

问题描述

在我的代码中，我创建了一个 TextBox 数组:

In my code I create an array of TextBoxes :

namespace TCalc
{
    public partial class MainWindow : Window
    {
        public TextBox[] pubAltArray;

        public MainWindow()
        {
            InitializeComponent();

            pubAltArray = new TextBox[10];

然后我使用以下代码以编程方式创建文本框:

Then I create the TextBoxes programmatically using the following code :

private void generatePublishedTxtBox()
{
    for (int i = 0; i < 10; i++)
    {
        TextBox pubAlt = new TextBox();
        grid_profile.Children.Add(pubAlt);
        pubAlt.SetValue(Grid.RowProperty, 1);
        ...
        pubAltArray[i] = pubAlt;
    }
}

当每个 TextBox 的内容发生变化时，我想运行一些例程:

Than I have some routine I want to run when the content of each TextBox changes :

private void doTheStuff(object sender, TextChangedEventArgs e)
{
...
} 

所以我尝试在定义新 TextBox 的过程中添加事件处理程序，但没有成功:

So I tried to add event handler during the definition of new TextBox however without success :

pubAlt.TextChanged += new System.EventHandler(doTheStuff());

或

pubAlt.TextChanged += RoutedEventHandler(calculateCorAlts());

对我有什么提示吗?

推荐答案

尝试:

pubAlt.TextChanged += new TextChangedEventHandler(doTheStuff);

或:

pubAlt.TextChanged += doTheStuff;

两条线做同样的事情.第二个只是第一行的简写，因为它使代码更易于阅读.

Both lines do the same thing. The second one is just shorthand for the first line since it makes code easier to read.
