i have an issue when i am trying to convert a file into byte array using this code
var fileByte = new byte[pic.ContentLength];
it converts the file but when file is uploaded it is corrupted. and when i tried the another code to convert the file ie
var pic = System.Web.HttpContext.Current.Request.Files["ImagePath"];
byte[] bytes = System.IO.File.ReadAllBytes(pic.FileName);
it thrown an exception like
Could not find file 'C:\\Program Files\\IIS Express\\slide2.jpg'.
after words i'd tried for this
byte[] b = StreamFile(pic.FileName);
private byte[] StreamFile(string filename)
{
FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read);
Create a byte array of file stream length
byte[] ImageData = new byte[fs.Length];
//Read block of bytes from stream into the byte array
fs.Read(ImageData, 0, System.Convert.ToInt32(fs.Length));
//Close the File Stream
fs.Close();
return ImageData; //return the byte data
}
but it also throw and exception like
Could not find file 'C:\\Program Files\\IIS Express\\slide2.jpg'.
First line of code doesn't convert file to byte array, it just creates a byte array with size of pic.ContentLength
.
Second example throws you an exception which clearly states that you don't have the image on specified path (defined by pic.FileName
).
To solve this, you should work with the request's file Stream
and write it into byte array.
var pic = System.Web.HttpContext.Current.Request.Files["ImagePath"];
byte[] bytes;
using (var stream = new MemoryStream())
{
pic.InputStream.CopyTo(stream);
bytes = stream.ToArray();
}
