问题描述
我是WCF的新手,我向项目中添加了示例WCF服务,但是当我尝试通过浏览器访问Webservice方法时,它显示空白窗口.我在Google上搜索了解决方案,但是在解决一个问题时又出现了另一个问题,我想知道如何在JSON格式的浏览器窗口中获取服务返回的值.
I am new to WCF and I have added a sample WCF service to my project but when I try to access webservice method through browser it shows blank window. I searched google for the solution but on solving one issue another issue arises I want to know how to get value returned by service in my browser window in json format.
我的代码是这样的:
[ServiceContract]
public interface IService
{
[OperationContract]
[WebGet(UriTemplate = "DoWork", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
int DoWork();
}
类是这样的:
public class Service : IService
{
private int counter=0;
public int DoWork()
{
counter++;
return counter;
}
}
Web.config就像这样:
Web.config is like this:
<?xml version="1.0"?>
