Hi,

I should read an image which type is png in my project. I have a folder named "Images". I put my image to this folder. I can read this image but can not convert it to byte [] .

I have an object which have a property named "Image" , and type of this property is byte[] . I should take the image which is read and set this image to my objects''s Image property. I tried this after exploring this issue a long time at net. How can ı convert the image to byte[] in Silverlight ? I couldn''t find a solution which can solve my problem.

Thanks for your replies in advance ..

推荐答案

创建字节数组并指定从中读取字节的文件非常简单
您需要导入System.IO

byte [] photodata = File.ReadAllBytes("C:\\ img.png");

祝你好运........

It''s quite simple create a byte array and specify the file from which to read the bytes
you need to import System.IO

byte [] photodata=File.ReadAllBytes("C:\\img.png");

Best of luck........

Mantu，
感谢您的答复.
当我为路径桌面设置图像时，它可以工作.
但是在项目中，我应该具有读取项目中图像的项目路径.

我尝试了我找到的解决方案，例如:

Mantu,
Thanks for your reply.
When I set an image in for path desktop, it works.
But in project I should have the project path to read the image in the project.

I tried which I find as solutions like :

string s1 = Environment.CurrentDirectory;
string s2 = Path.GetDirectoryName(Application.Current.ToString());
string s3= System.IO.Directory.GetCurrentDirectory();

但是所有这些代码块都显示了桌面"C:\ Users \ MyUser".

如何在Silverlight中获取projet目录?
感谢您的提前答复.

But all these code blocks shows the desktop "C:\Users\MyUser".
