This example shows how to convert an image into a byte array.
Sample Code:
public byte[] ImageToByteArray(Image img)
{
MemoryStream ms = new MemoryStream();
img.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
return ms.ToArray();
}

This example shows how to convert a byte array into an image.
Sample Code:
public Image ByteArrayToImage(byte[] data)
{
MemoryStream ms = new MemoryStream(data);
Image returnImage = Image.FromStream(ms);
return returnImage;
}

This example shows how to use a try-catch statement for exception handling.
Sample Usage:
try
{
//Do something
}
catch(Exception ex)
{
//Handle exception
}
finally
{
//This code is always executed
}
This example shows how much time takes a procedure/function/code. It is useful for micro-benchmarks in code optimization. To do this, We use the Stopwatch class in System.Diagnostics namespace.
Sample Code:
// Create stopwatch
Stopwatch stopwatch = new Stopwatch();
// Begin timing
stopwatch.Start();
// Do something
for (int i = 0; i < 10; i++)
{
Thread.Sleep(10);
}
// Stop timing
stopwatch.Stop();
// Write result
Console.WriteLine("Total Time: {0}", stopwatch.ElapsedMilliseconds);
The conditional compilation directives are used to conditionally include or exclude portions of a source file. This example shows how to use of preprocessor directives like “#define”, “#undef”, “#if”, etc. Firstly, you should add your variables above the “using”.
#define Debug // Debugging on #undef Trace // Tracing off
#if Debug
//To do something
#endif
#if Trace
//To do someting
#endif
