CSV Serializer Based on .NET Expression Trees

CSV Serializer for .NET

Features

• Flattens object hierarchies
• Only includes members with DataMemberAttribute if the containing type has DataContractAttribute
• Supports anonymous types
• IFlattener allows external code to flatten an instance's member's values to an IList<object>
• Supports dynamic columns: column names and keys can be passed after enumerable to serialize

CSV Usage

using (var stream = File.Create("example.csv"))
{
    Cameronism.Csv.Serializer.Serialize(stream, someIEnumerable);
}

CSV With Dynamic Columns

Column headings and keys can be provided to serialize after instance properties and fields. Dynamic columns require an indexer, the indexer will be called once for every key for every item in the enumerable.

using (var stream = File.Create("extra-columns.csv"))
{
    Cameronism.Csv.Serializer.Serialize(stream, anotherIEnumerable, new[] {
		new KeyValuePair<string, SomeType>("Gate", keeper),
		new KeyValuePair<string, SomeType>("Key", master),
		new KeyValuePair<string, SomeType>("Only", zuul),
	});
}

IFlattener Usage

var nestedInstance = new
    { 
        Hello = "World",
        Foo = new 
        {
            Bar = 42,
            Bop = Guid.Empty,
        },
    };

IFlattener flattener = Cameronism.Csv.Serializer.CreateFlattener(nestedInstance.GetType());
IList<object> values = flattener.Flatten(nestedInstance);

Console.WriteLine(String.Join("\n", values));

/*
World
42
00000000-0000-0000-0000-000000000000
*/
