Lincolle4net

By importing this library in your project, you are going to access some methods as extensions which will help you while filtering Linq and Collections in C#.

For now the current version supports only WhereIf on List, Enumerable, Queryable, Stack, Dictionary and Collection.

var filter = "DRC";
var countries = (new List<string>() { "USA", "Canada" ,"DRC", "Uganda", "China" })
  .AsQueryable()
  .WhereIf(!string.IsNullOrEmpty(filter), c => c == filter);

Note that, on each call of WhereIf, an inline IF condition is applied on specified generics. Without using this package, the above code could be written as below:

var filter = "DRC";
var countries = (new List<string>() { "USA", "Canada" ,"DRC", "Uganda", "China" })
  .AsQueryable();

if(!string.IsNullOrEmpty(filter))
{
    countries.Where(c => c == filter);
}

Use this library while filtering Dictionaries.

var dic = new Dictionary<string, string>
{
    { "test", "val" },
    { "test2", "val2" }
};
var filter = "va";

var data = dic.WhereIf(!string.IsNullOrEmpty(filter), c => c.Value.StartsWith(filter));

Roadmap

• WhereIf
• AddIf
• RemoveIf
