如何在Web解决方案中的项目之间引用类

Question

I have a project store a Address class which I want both Web Service project and Web project to use.

Project 1: (holding Address class)

namespace GeoClass
{
    public partial class Address 
    {        
        private string city { get; set; };        
        private string street { get; set; };       
        private string zip { get; set; };
    }
}

• Web Service project: I added the GeoClass as reference

   using GeoClass; namespace WSGeo { public class jsonGeo : System.Web.Services.WebService { [WebMethod} public jsonOut GetAddress(Address inputAddr) { //do something } } } 

• In Web application which is add the WebService project as web service andd add the Project 1 as reference. I call the method in Webservice likes this:

   using GeoClass; Address inputAddress = GetInputAddress(); //This function pull the data from the text boxes string WSResult; WSGeo jsonGeo = new WSGeo; WsResult = WS.jsonGeo.GetAddress(inputAddress); // I have in invalid argument error right here 

Did I miss something here? Thanks

Answer 1

I found the answer here: C# Web Service and Web Site sharing library, service returns different "type" of library object

I only have this issue with the Web application framework 3.5 (library and web service projects are framework 4.5), when I built another one with framework 4.5 (all web app, web service, and library) I haven't experienced this problem yet.
