C# Shortcuts (Using Statement)

Often, you will need to allocate a system resource or network resources, etc. Each time you need such a resource, there are three crucial steps to go through:

You will have the resource you use, and then get rid of it. If you forget to properly dispose of it, you create a memory or resource leaks. This is best illustrated through the following models

// Step-A. Allocation of desired object here
Font myFont = new Font("Arial", 12.0f);
try
{
     // Step-B. use the resource (myFont) here
}
finally
{
     // Step-C. Dispose your object here
     if (myFont != null)
        ((IDisposable)myFont).Dispose();
}

Using allows us to use to compress this to:

//Allocate the desired resource here
using (Font myFont = new Font("Arial", 12.0f))
{
    // Use the resource here
}
// The best part is that Disposal is automatic.
