C# The process cannot access the file because it is being used by another process
The process cannot access the file because it is being used by another process.
This error message is mostly comes up,
when you try to access a file which is opened by
another process.
You may open an image file in one of your form in a
picturebox with using
ImageFromFile or something.
I mostly use
memorystream to open an image.
After read it in
byte[] write it into a stream and close it.
You can check whether a file is being used or not with a simple function.
Try to open a file with none share.
?
public
bool
IsFileUsedbyAnotherProcess(
string
filename)
{
try
{
File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.None);
}
catch
(System.IO.IOException exp)
{
return
true
;
}
return
false
;
}
This function will return true if
the file because it is being used by another process or not.
