I am working in win forms. Getting errors while doing following operation.
It shows me System.OutOfMemoryException
error when i try to run the operation around 2-3 times continuously. Seems .NET is not able to free the resouces used in operation. The file i am using for operation is quite big, around more than 500 MB.
My sample code is as below. Please help me how to resolve the error.
try
{
using (FileStream target = new FileStream(strCompressedFileName, FileMode.Create, FileAccess.Write))
using (GZipStream alg = new GZipStream(target, CompressionMode.Compress))
{
byte[] data = File.ReadAllBytes(strFileToBeCompressed);
alg.Write(data, 0, data.Length);
alg.Flush();
data = null;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
A very rough example could be
// destFile - FileStream for destinationFile
// srcFile - FileStream of sourceFile
using (GZipStream gz = new GZipStream(destFile, CompressionMode.Compress))
{
byte[] src = new byte[1024];
int count = sourceFile.Read(src, 0, 1024);
while (count != 0)
{
gz.Write(src, 0, count );
count = sourceFile.Read(src, 0, 1024);
}
}
// flush, close, dispose ..
So basically I changed your ReadAllBytes
to read only chunks of 1024 bytes.
