I'm trying to upload a file. However, much of the material I find on the Internet explains how to save the file to a folder on the server, but for my solution I just needed to buffer. Is it possible? I upload the file to the server buffer, then read and clean.
Obs.: I am using telerik components, and need to read / import an Excel file.
Thanks
So if you use a binary stream, the approach to buffer it regardless of the context of execution (asp.net vs winforms or whatever) is pretty common:
public static byte[] ReadFile(string filePath)
{
byte[] buffer;
FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
try
{
int length = (int)fileStream.Length; // get file length
buffer = new byte[length]; // create buffer
int count; // actual number of bytes read
int sum = 0; // total number of bytes read
// read until Read method returns 0 (end of the stream has been reached)
while ((count = fileStream.Read(buffer, sum, length - sum)) > 0)
sum += count; // sum is a buffer offset for next reading
}
finally
{
fileStream.Close();
}
return buffer;
}
Also, check out this:
The default FileUpload component presents you the file as a Byte[] - you could just wrap it in a MemoryStream:
var strm = new MemoryStream(fileUpload.PostedFile.Contents);
// I think its PostedFile.Contents, something like that anyway
