That error message is clear right?

Hi, as the error message is saying it, the FileInfo cannot be serialized/deserialized because the deserialization needs a constructor without parameters. So what you could do is to build your own FileInfo/DirectoryInfo class. Also you could try to customize the deserialization process, but i'm not sure if this is possible. Regards Sebastian

http://www.dalepreston.com/Blog/2005/02/returning-custom-classes-from-web.html[^] I want todo returning FileInfo type because i tried to file reading from server, but these files are encrypted and needed to be open from special project then read. the files are in server and size is out of 1 GB. my question is about a method to be able to read file from service and returning to the project... Thanks for replies.

If you need infos about the file from the server, you have to create your own FileInfo-class containing the properties you need. public class MyFileInfoClass { public Name { get; set; } public FullName {get; set; } } Just create this object before you return the result of your method and fill the properties using the FileInfo on your server. Btw. if you want to read the content of the file you have to transfer the file and not the FileInfo. Regards Sebastian

the way you suggest, didn't solve my problem, if possible, please give me another solution i defined the class MyFileInfo and as member used FileInfo member to get the variable type but same error occured FileInfo in MyFileInfo cannot be serialized :confused:

You can not use FileInfo in your result because it is not deserializable. What I suggested was that you create your class containing some properties of FileInfo you want to transport through the wire. But pls do not use the FileInfo-Type within the result, it will not work.
