Next and prev links for example in a view: var next = ("page",Model. It is possible to retrieve the associated EntityManager of the current QueryBuilder, its DQL and also a Query object when you finish building your DQL. QueryBuilder::UPDATE, which returns value 2. Var url = QueryHelpers.AddQueryString(uriBuilder.ToString(),allQPs) There're currently 3 possible return values for getType (): QueryBuilder::SELECT, which returns value 0. Var allQPs = queryParams.ToDictionary(k => k.Key, k => k.Value.ToString()) Var queryParams = QueryHelpers.ParseQuery(uriBuilder.Query) Throw new Exception("nameValues: has more parameters then values or more values then parameters") I use this as extention method, works with any number of params: public static string AddOrReplaceQueryParameter(this HttpContext c, params string nameValues) To keep up to date with any changes, you can check out my blog post about this here: Var fullUri = baseUri + qb.ToQueryString() Reconstruct the original URL with new query string Use the QueryBuilder to add in new items in a safe way (handles multiples and empty values) Items.RemoveAll(x => x.Key = "key2" & x.Value = "val2") // Remove specific value for key Items.RemoveAll(x => x.Key = "ke圓") // Remove all values for key At this point you can remove items if you want Var items = query.SelectMany(x => x.Value, (col, value) => new KeyValuePair(col.Key, value)).ToList() Convert the StringValues into a list of KeyValue Pairs to make it easier to manipulate Var query = QueryHelpers.ParseQuery(uri.Query) Var baseUri = uri.GetComponents(UriComponents.Scheme | UriComponents.Host | UriComponents.Port | UriComponents.Path, UriFormat.UriEscaped) Parse URI, and grab everything except the query string.

The Code // Raw URI including query string with multiple parameters Just to point them out, here are the two important classes we'll be using: QueryHelpers, StringValues, QueryBuilder.

The easiest and most intuitive way to take an absolute URI and manipulate it's query string using ASP.NET Core packages only, can be done in a few easy steps: Install Packages If you want to add a parameter on to the query string, you can use another method on QueryHelpers: var parametersToAdd = new This is how the dictionary handles multiple query string parameters with the same name. Note that unlike ParseQueryString in System.Web, this returns a dictionary of type IDictionary in ASP.NET Core 1.x, or IDictionary in ASP.NET Core 2.x or greater, so the value is a collection of strings.
Var queryDictionary = .ParseQuery(uri.Query) To parse it into a dictionary: var uri = new Uri(context.RedirectUri) If you are using ASP.NET Core 3.0 or greater, WebUtilities is now part of the ASP.NET SDK and does not require a separate nuget package reference. If you are using ASP.NET Core 1 or 2, you can do this with in the package.
