How to Convert Bitmap to Byte Array in order to Display Image from Resource File
I need to convert a bitmap to byte array in order to display an image from resource file on a web page in a web application.
I read the image file from App_GlobalResources resources by explicitly calling the resource file.
But I had to convert to a byte array in order to send the bitmap file as a response.
The trick is using the MemoryStream object from the System.IO.MemoryStream namaspace.
'Read bitmap resource
Dim bitmap As Bitmap = Resources.GlobalSiteResources.logo
'Convert to Byte array
Dim ConvertedByteArray As Byte()
Using memorystream As New System.IO.MemoryStream
bitmap.Save(memorystream, bitmap.RawFormat)
ConvertedByteArray = memorystream.ToArray
End Using
And here is the all code I used to display an image file from web applications resources that are stored in a Global Resource file in App_GlobalResources ASP.NET folder.
'SET Current UI Culture
Dim currentCultureInfo As CultureInfo = CultureInfo.GetCultureInfo("tr-TR")
System.Threading.Thread.CurrentThread.CurrentUICulture = currentCultureInfo
'Read bitmap resource
Dim bitmap As Bitmap = Resources.GlobalSiteResources.logo
'Convert to Byte array
Dim ConvertedByteArray As Byte()
Using memorystream As New System.IO.MemoryStream
bitmap.Save(memorystream, bitmap.RawFormat)
ConvertedByteArray = memorystream.ToArray
End Using
'Response
Response.Buffer = True
Response.ContentType = "Image/BMP"
Response.BinaryWrite(ConvertedByteArray)
