Allow special characters in Web Api Get function

Question

I am trying to pass a special characters to a custom function in Web API. The function works if I don't pass special characters. The special characters that I am referring to are '#' ,'&' ,....

[HttpGet] [EnableQuery(MaxExpansionDepth = 5)] public IQueryable<Test> QueryTest(string Query) { var dbTest = db.Test.AsQueryable(); return dbTest; }

Which characters are you referring to and what exactly happens? — Onkel Toob

The characters probably have to be encoded in order to be received correctly by the backend and not be treated as something else by the HTTP protocol. — silkfire

An option is to use a post method and pass your parameter through a json object in the body message.

[HttpPost] public IQueryable<Test> QueryTest(QueryTestRequest request) { var dbTest = db.Test.AsQueryable(); return dbTest; } public class QueryTestRequest { public string Query {get; set;} }

URL encoding is the way to go. This should be done as a default you don't even think of, solves so many issues. Set the Encoding of the WebClient

client.Encoding = Encoding.UTF8;
