无法将'byte []'隐式转换为'byte'

Question

My given code has an error of type conversion

 int imglength = FileUpload2.PostedFile.ContentLength;
 byte imgarray=new byte[imglength];

Answer 1

You're trying to assign an array of bytes ( byte[] ) to a single byte, hence the error.

Try the following code:

byte[] imgarray = new byte[imglength];

Answer 2

you can not assign a byte array to byte

try this

byte[] bytearray = new byte[imglength];

Answer 3

结构是这样的

byte[] Buffer = new byte[imglength];

Answer 4

You can use the below code:

int imageSize = fuImage.PostedFile.ContentLength;
System.IO.Stream imageStream = fuImage.PostedFile.InputStream;
byte[] imageContent = new byte[imageSize];
int status = imageStream.Read(imageContent, 0, imageSize);

This code coverts postedfile to byte stream

Answer 5

Check this:

int imgLength = FileUpload2.PostedFile.ContentLength;
byte[] revLength= BitConverter.GetBytes(imgLength);
Array.Reverse(revLength);
byte[] imgLengthB = revLength;
