问题描述
我需要将一个图像文件拖放到我的 WPF 应用程序中.当我将文件放入时，我目前有一个事件触发，但我不知道下一步该怎么做.我如何获得图像?sender 对象是图像还是控件?
I need to drop an image file into my WPF application. I currently have a event firing when I drop the files in, but I don't know how what to do next. How do I get the Image? Is the sender object the image or the control?
private void ImagePanel_Drop(object sender, DragEventArgs e)
{
//what next, dont know how to get the image object, can I get the file path here?
}
推荐答案
这基本上就是你想做的.
This is basically what you want to do.
private void ImagePanel_Drop(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{
// Note that you can have more than one file.
string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
// Assuming you have one file that you care about, pass it off to whatever
// handling code you have defined.
HandleFileOpen(files[0]);
}
}
另外，不要忘记在 XAML 中实际连接事件，以及设置 AllowDrop 属性.
Also, don't forget to actually hook up the event in XAML, as well as setting the AllowDrop attribute.
<StackPanel Name="ImagePanel" Drop="ImagePanel_Drop" AllowDrop="true">
...
</StackPanel>
