WPF DataContext 语法 - 从 C# 转换为 VB

发布于 2024-09-02 04:45:32 字数 253 浏览 1 评论 0原文

目前正在学习自学 WPF 教程。通常我可以在心里从 C# 转换到 VB，没有任何问题，但这种 C# 语法不熟悉。用VB怎么写呢？

Private void Button_Click(object sender, RoutedEventArgs e)
{
    ((Person)DataContext).FirstName = "blah blah"
}

我最喜欢的在线转换器对此感到窒息……也许是因为他们不支持 WPF？

Currently working through a Teach Yourself WPF tutorial. Usually I can mentally convert from C# to VB without any problem but this C# syntax is unfamiliar. How is it written in VB?

Private void Button_Click(object sender, RoutedEventArgs e)
{
    ((Person)DataContext).FirstName = "blah blah"
}

My usual fave online converters are choking on this ... perhaps because they don't do WPF?

试试这个

Private Sub Button_Click(ByVal sender As System.Object, ByVal e as RoutedEventArgs) Handles Button.Click
 DirectCast(DataContext, Person).FirstName = "blah blah"
End Sub

try this

Private Sub Button_Click(ByVal sender As System.Object, ByVal e as RoutedEventArgs) Handles Button.Click
 DirectCast(DataContext, Person).FirstName = "blah blah"
End Sub
