I am using the following function to convert binary data to text:
public string BinaryToText(byte[] data)
{
MemoryStream stream = new MemoryStream(data);
StreamReader reader = new StreamReader(stream, encoding.UTF8);
string text = reader.ReadTod();
return text;
}
But I get an OutOfMemoryException for 30Mb data.
How can I solve this problem and convert data larger than 100Mb, using this or any better method?
Try this instead:
public string BinaryToText(byte[] data)
{
return Encoding.UTF8.GetString(data);
}
It will consume less memory. If it still runs out of memory, you'll need to read it in chunks - but how you are using the data will determine if that is possible. What are you doing with the returned string?
Also I will reiterate my earlier question: Is the input data really UTF8 data?
If you can handle the data being returned as multiple strings, you can do something like this:
public IEnumerable<string> BinaryToStrings(byte[] data, int maxStringLength)
{
var buffer = new char[maxStringLength];
using (MemoryStream stream = new MemoryStream(data))
using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
{
while (true)
{
int count = reader.Read(buffer, 0, maxStringLength);
if (count == 0)
{
break;
}
yield return new string(buffer, 0, count);
}
}
}
Then you can call that in a foreach loop like so:
foreach (string chunk in BinaryToStrings(data, 1024))
{
// Do something with 'chunk'...
}
