You can call the button_click event by simply passing the arguments to it:
您可以通过简单地将参数传递给它来调用 button_click 事件：
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
SubGraphButton_Click(sender, args);
}

You can simply call it:
你可以简单地调用它：
SubGraphButton_Click(sender, args);
Now, if your SubGraphButton_Clickdoes something with the args, you might be in trouble, but usually you don't do anything with them.
现在，如果你SubGraphButton_Click对 args 做了一些事情，你可能会遇到麻烦，但通常你不会对它们做任何事情。

Usually the better way is to trigger an event (click) instead of calling the method directly.
通常更好的方法是触发一个事件（点击）而不是直接调用方法。

Add it to the instance of the Click delegate:
将其添加到 Click 委托的实例中：
ChildNode.Click += SubGraphButton_Click
ChildNode.Click += SubGraphButton_Click
which is inkeeping with the pattern .NET events follow (Observer).
这与 .NET 事件遵循的模式（观察者）保持一致。

You can easily do it by the following piece of code (assuming that name of your button is btnButton):
您可以通过以下代码轻松完成（假设您的按钮名称是btnButton）：
btnButton.PerformClick();

You can perform different approaches to work around this. The best approach is, if your both buttons are suppose to do the same job, you can define a third function to do the job. for example :
您可以执行不同的方法来解决此问题。最好的方法是，如果你的两个按钮都假设做同样的工作，你可以定义第三个功能来完成这项工作。例如 ：
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
myJob()
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
myJob()
}
private void myJob()
{
// Your code here
}
but if you are still persisting on doing it in your way, the best action is :
但如果你仍然坚持按照自己的方式去做，最好的做法是：
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
SubGraphButton_Click.PerformClick();
}

you can call the button_click event by passing..
您可以通过传递来调用 button_click 事件..
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
SubGraphButton_Click(sender, args);
}
Also without passing..
也没有通过..
private void SubGraphButton_Click(object sender, EventArgs args)
{
}
private void Some_Method() //this method is called
{
SubGraphButton_Click(new object(), new EventArgs());
}

private void PictureBox1_Click(object sender, EventArgs e)
{
MessageBox.Show("Click Succes");
}
private void TextBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == 13)
{
PictureBox1_Click(sender, e); //or try this one "this.PictureBox1_Click(sender, AcceptButton);"
}
}

For me this worked in WPF
对我来说，这在 WPF 中有效
private void Window_KeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
RoutedEventArgs routedEventArgs = new RoutedEventArgs(ButtonBase.ClickEvent, Button_OK);
Button_OK.RaiseEvent(routedEventArgs);
}
}

Use InvokeOnClick event. it works even if the button is invisible/disabled
使用 InvokeOnClick 事件。即使按钮不可见/禁用，它也能工作
