嘿我没有得到任何地方把wcf变成一个宁静的服务。所以我在想，如果当你开始一个WCF服务应用程序在这里的一些人可以利用的基本代码：将WCF服务转换为RESTful应用程序？
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService1
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{
[OperationContract]
string GetData(int value);
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
// TODO: Add your service operations here
}
// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class CompositeType
{
bool boolValue = true;
string stringValue = "Hello ";
[DataMember]
public bool BoolValue
{
get { return boolValue; }
set { boolValue = value; }
}
[DataMember]
public string StringValue
{
get { return stringValue; }
set { stringValue = value; }
}
}
}
，服务：
namespace WcfService1
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class Service1 : IService1
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
public CompositeType GetDataUsingDataContract(CompositeType composite)
{
if (composite == null)
{
throw new ArgumentNullException("composite");
}
if (composite.BoolValue)
{
composite.StringValue += "Suffix";
}
return composite;
}
}
}
所有我已经没有启动这个WCF服务应用程序，打开了另一个VS2010灵魂提示，它带有一个带有文本框按钮和标签的基本表单，并在另一个解决方案中拷贝了serviceapp的服务位置，所以当我键入一个数字时，我得到服务的响应。
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
public ServiceReference1.Service1Client testClient = new ServiceReference1.Service1Client();
private void button1_Click(object sender, EventArgs e)
{
label1.Text = testClient.GetData(Convert.ToInt32(textBox1.Text));
}
}
}
真的很快又脏，但达到其目的。
现在，如果任何人可以帮助代码，你怎么把它变成一个宁静的服务？我的配置文件的
结束部分：
<system.serviceModel>
<services>
<service name="WcfService1.Service1" behaviorConfiguration="WcfService1.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="wsHttpBinding" contract="WcfService1.IService1">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.

<identity>

</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>

与Justins配置代码编辑更新：
所以，当过我触摸配置文件我通常的错误是：无法添加服务。服务元数据可能无法访问。确保您的服务正在运行，揭露元

啊，是的，WCF很喜欢REST（正如我所提到的）。不过，我已经从一篇旧的MSDN文章更新了我的答案，即如何针对您的情况更具体地实现这一点。 – 2012-03-24 18:25:00
