从不同的线程中读取多个WPF文本框控件中的文本 [英] Reading text from multiple WPF textbox controls from a different thread

问题描述

在我的WPF应用程序中，我需要从几个文本框中读取文本.因为代码在与UI不同的线程中运行，所以我需要使用Dispatcher.invoke().

In my WPF application I need to read text from several textboxes. Because the code is running in a different thread to the UI, I need to use Dispatcher.invoke().

目前，我正在使用一个效果很好的文本框，但现在我需要所有文本.我是否需要为每个文本框编写Dispatcher.invoke，或者是否可以编写函数，以便传递文本框控件引用并返回文本?

At the moment I’m working with one textbox which works fine, but now I need all the texts. Do I need to write a Dispatcher.invoke for each textbox or is there a way to write a function so I pass in a textbox control reference and it returns the text?

推荐答案

您只需在同一Invoke调用中从所有TextBox字段中获取文本即可.

You could just grab the text from all the TextBox fields in the same Invoke call.

public MainWindow()
{
    InitializeComponent();

    Thread thread = new Thread(new ThreadStart(this.ThreadFunc));
    thread.Start();
}

private delegate void InvokeDelegate();
private void ThreadFunc()
{
    Dispatcher.Invoke(new InvokeDelegate(() =>
    {
        Debug.WriteLine(this.textBox1.Text + this.textBox2.Text);
    }));
}

没有理由您必须打多个电话.

There's no reason you would have to make multiple calls.
