如何检查Windows Phone 7和C＃中两个图像的来源是否相同？

Question

How can I check if two images have same source in wp7 C#? I am doing this but it's not working.

if(image1.source.tostring()==image2.source.tostring()){}

Answer 1

I can't see any easy way to do that. ImageSource is an abstract class and can be anything therefore it is hard to compare. However the most likely implementation is BitmapImage . So you can check of its type and if it is BitmapImage or IUriContext you can cast it and compare the BaseUri property.

Answer 2

您正在比较参考，比较值...

if(image1.source.ToString().Equals(image2.source.ToString())) {}

Answer 3

You can compare both of the images with the help of BitmapImage

BitmapImage image1= new BitmapImage(new Uri("your first image relative path", UriKind.Relative))

BitmapImage image2= new BitmapImage(new Uri("your second image relative path", UriKind.Relative))

if(image1==image2)
{
MessageBox.show("Image matched.");
}
else
{
MessageBox.Show("Not matched.");
}
