Listing 6-11

What is the correct way to get the file content into a byte array?

Listing 6-11 shows the following C# code:

Code:

Byte myByteArray[];
System.IO.Stream myStream;
 
myStream = FileUpload.FileContent;
myByteArray = myStream.ToArray();

I'm getting two errors from this code. The first is a syntax error on the first line which I was able to correct by moving the brackets:

Code:

Byte[] myByteArray;

The second error that I'm getting is on the fourth line. The System.IO.Stream object does not have a ToArray() method. The VB example above it uses System.IO.MemoryStream, which does have a ToArray() method, but I have to cast the file content:

Code:

myStream = (MemoryStream)FileUpload.FileContent;

...which builds but is throwing an invalid cast error when I run it.

Ultimately I need to pass this into an insert parameter...

Code:

srcDocuments.InsertParameters["DocumentContent"].DefaultValue = myByteArray.ToString();

...and then dump it into SQL but the given method here for doing that is not working.

Hi there,

What about:

Code:

myFileUpload.FileBytes

It returns a byte array....

Cheers,
