Question

如何在wpf中获取图像的当前路径？

我正在尝试构建一个通用函数，通过在图像名称的末尾添加“焦点”将图像更改为其他图像，btu似乎无法获取当前路径，因此我可以制作变化

任何想法？

private void image1_MouseEnter(object sender, MouseEventArgs e)
{
        string buf = ((BitmapImage)(sender as Image).Source).UriSource.ToString();
        string pack = buf.Substring(0, buf.LastIndexOf('.')) + "focus" + buf.Substring(buf.LastIndexOf('.'));

        SetImageFullURI(sender as Image, pack);
}

Answer 1

您可以在代码中修改Image的基础来源，例如：... i是您定义的Image来自XAML或在别处定义的。在此示例中，未使用path;但是，当您在问题中附加focus时，您会使用它。

Image i = new Image();

BitmapImage bi = i.Source as BitmapImage;
bi.BeginInit();

Uri uri = bi.UriSource;
String path = uri.AbsolutePath;
String newPath = @"C:\Images\blah.png";
Uri newUri = new Uri(newPath);

bi.UriSource = newUri;
bi.EndInit();

编辑：

根据您的代码尝试这个...

string buf = ((BitmapFrame)(sender as Image).Source).BaseUri.ToString();

Answer 2

您可以使用BitmapImage个对象，并在必要时将image.Source指向他们

BitmapImage具有bitmapImage.UriSource属性

获取当前图像路径
