Hi,

I've been looking at a csv parse I found on CodeProject, and I don't
recognise the syntax used in the constructors. Here's an example:

public CachedCsvReader(TextReader reader, bool hasHeaders)
: this(reader, hasHeaders, DefaultBufferSize)
{
}

Is this basically saying pass through to the constructor that takes
(reader, hasHeaders, DefaultBufferSize) ?

Thanks.

Yes.

The class uses 2 constructors. The "main constructor" has 3 parameters:
TextReader, hashHeaders and a BufferSize.

If somebody creates an object _without_ declaring a buffer size he uses:

public CachedCsvReader(TextReader reader, bool hasHeaders)

In this case the "main constructor" is called with using a
DefaultBufferSize.

In addition to what the gentleman said above me, this also applies to
derived classes, in the sense if you want to call a base class
constructor from a derived class, you could use the same syntax just
replace this() with base()

Yup. See
