Cum sa salvezi un stream direct intr-un fisier

Posted on 14:51 by Unknown
Cred ca este a 2-a oara când întâlnesc aceasta cerința in decurs de câteva săptămâni.
Se da un stream și o locație unde trebuie salvat, se cere să se salveze conținutul la stream in locația data. Din păcate API-ul de .NET nu ne permite să facem acest lucru doar dintr-un apel.
O soluție propusa este următoarea:
        /// <summary>
/// Save the stream to the given location.
/// </summary>
/// <param name="stream">The stream.</param>
/// <param name="filePath">The file path where is saved.</param>
/// <param name="blockSize">The size of the buffer(in kB)</param>
public static void SaveStream(this Stream stream,String filePath,SeekOrigin seekOrigin=SeekOrigin.Begin,int blockSize=1)
{
//Set the poinder to the begin of the stream.
if(stream.CanSeek && seekOrigin==SeekOrigin.Begin)
{
stream.Seek(0, SeekOrigin.Begin);
}

//Removed the existing file.
if (File.Exists(CommandLineArguments.Instance.File))
{
File.Delete(CommandLineArguments.Instance.File);
}

//Save the stream to the given location.
using (var streamWrite = File.Create(CommandLineArguments.Instance.File))
{
byte[] buffer = new byte[1024*blockSize];
int read;

while ((read = stream.Read(buffer, 0, buffer.Length)) > 0)
{
streamWrite.Write(buffer, 0, read);
}
}
}
Iar un exemplu de utilizare:
Stream stream=...;
stream.Save("d:/a.txt");
In funcție de necesitați acest exemplu se poate extinde. Din păcate nu putem să facem un extension method pe File deoarece este o clasa statica.
