how to prevent the Image.FromFile() method to lock the file

Question

I am using following code to put JPG\'s into a DataGridView\'s Image cell.

If strFileName.ToLower.EndsWith(\".jpg\") Then
     Dim inImg As Imag         


        

Answer 1

I encountered the same situation and used this code:

' Create memory stream from file
Dim ms As New MemoryStream()
' Open image file
Using fs As New FileStream(.FileName, FileMode.Open, FileAccess.Read)
    ' Save to memory stream
    fs.CopyTo(ms)
End Using

' Create image from the file's copy in memory
Dim img = Image.FromStream(ms)

I didn't dispose the memory stream because it allows to save the image later using exactly the same encoding as the original file, using this code:

img.Save(someOtherStream, img.RawFormat)
