May I pass list as a parameter in web api method?

Question

public static Document GetDocument(List<long> IdList)
{
          //my code
}

I am passing the parameter from UI as:-

 getMulipleDocument: function (documentId) {
            return $http({
                url: apiUrl + "Info/GetDocument?IdList=" + documentId,});

Do some few modification in your code. Use FromUri to build your list

public static Document GetDocument([FromUri]List<long> IdList)
{
          //my code
}

Build url like this

var requestUrl = apiUrl + "Info/GetDocument?IdList=" + id1 + "&IdList=" + id2;

Build requestUrl like query string starting with first id by ?IdList= and then append next ids to url by using &IdList=

In above case you can pass only one id as well bu using only ?IdList= and followed by your id
