c# - Fix a string from supplied data -

let's have these items in list full of strings:

• cash
• cheque
• postal order
• credit card
• bank transfer
• etc... etc... etc...

i found nice thing called "levenshteindistance". working point. not return correct string if type wrong.

i thinking of going regex side this.

basically want type, example, "chq" , should return "cheque".

i have code try not working correctly:

foreach (string entry in lsbsupplieddata.items) {     entr = entry.trim().replace(" ", "");     regex = new regex("^[" + inputstring + "]+$", regexoptions.ignorecase);      if (regex.ismatch(inputstring))     {         proposal = entry;         //break;     } } 

can please me right direction? have list items should suggest, @ max 20 items (not big, performance not big issue).

you can try this:

var words = new[] { "cash", "cheque" ... };  string search = "chq";  var results = words              .where(x => x.tolower()                         .intersect(search.tolower().distinct()).count() >= search.length); 

this work , ignore case sensitivity , order of letters ex if type cqh still return cheque, if don't want happen, requires more work.also can change where first or firstordefault if want single result instead of matches.

update: here version doesn't ignore order of letters:

var result = words             .firstordefault(x => x.tolower().where(search.contains).sequenceequal(search));
