The system cannot find the file specified. The system cannot find the file specified.Īn error similar to the one above is the Could not load file or assembly 'assembly' or one of its dependencies. Could not load file or assembly 'assembly' or one of its dependencies. Notice that no filename is present in the exception message and in this case, the Filename property on FileNotFoundException is null. To find the cause of this error you will need to look through the stack trace, which hints that this is during Assembly.LoadFile. Unlike the error thrown on reading the missing file, messages from the System.Reflection namespace are harder to understand. (Exception from HRESULT: 0x80070002)Īt (String path, Evidence evidence)Īt (String path)Īt (String args) in APP_PATH\Program.cs:line 20 But the exception message is different: System.IO.FileNotFoundException: The system cannot find the file specified. In this scenario, the program still throws a FileNotFoundException. The error can be re-created like this: tryĪssembly.LoadFile("c:\\Nonexisting.dll") This error is typically thrown when trying to load an assembly that doesn't exist. ➡️ Reduce errors by 90% with elmah.io error logging and uptime monitoring ⬅️ Would your users appreciate fewer errors?

I've seen code parsing the exception message to get the name of the missing file, which is kind of a downer when the absolute path is available right there on the exception :) In the example I simply create the missing file by using the Filename property. If you want to present the user with the path or maybe create the file when not found, there is a nifty property available on FileNotFoundException: catch (FileNotFoundException e) The exception message contains a nice error description, as well as an absolute path to the missing file. This type of FileNotFoundException actually contains all the information needed to debug the problem. In the example above, the program will print an output to the console looking similar to this: System.IO.FileNotFoundException: Could not find file 'APP_PATH\bin\Debug\non-existing.file'.įile name: 'APP_PATH\bin\Debug\non-existing.file'Īt System.IO._Error.WinIOError(Int32 errorCode, String maybeFullPath)Īt System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost)Īt System.IO.FileStream.ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost)Īt System.IO.StreamReader.ctor(String path, Encoding encoding, Boolean detectEncodingFromByteOrderMarks, Int32 bufferSize, Boolean checkHost)Īt System.IO.File.InternalReadAllText(String path, Encoding encoding, Boolean checkHost)Īt System.IO.File.ReadAllText(String path)Īt (String args) in APP_PATH\Program.cs:line 19ĪPP_PATH will be the absolute path to the file that cannot be found. I'm trying to load a file that doesn't exist on the file system ( non-existing.file). This type of error can be re-created using a single line of code: try Could not find file 'filename'Īs the message says, you are trying to load a file that couldn't be found. The Message property on FileNotFoundException gives a hint about what is going on. Let's dig into the different causes of this error. At least I did while digging down into the details for this post. You may think you know everything there is to know about this exception, but I bet there is something left for you to learn.

But, there are actually multiple scenarios that can trigger this exception. Admitted! In all instances this error is caused by trying to access a file that isn't there. Today, I want to help you track down and fix a very common and very well known exception, System.IO.FileNotFoundException.
