参考别人的例子,加入跨域访问部分,留作参考.

WebServices 项目: Service1 类和 Person类 注意因为是独立的Service项目,所以需要加入2个xml文件,实现跨域访问,加在根目录下

clientaccesspolicy.xml和crossdomain.xml

public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        
public string HelloWorld()
        {
            
return "Hello World";
        }

        [WebMethod]
        
public Person[] GetPeople()
        {
            List
<Person> People = new List<Person>()
        {
           
new Person{ Name="Jack",Age=12},
           
new Person{ Name="Tom",Age=22},
           
new Person{ Name="Simon",Age=32},
           
new Person{ Name="Richard",Age=26}
        };

            
return People.ToArray();
        }

    }

    
public class Person
    {
        
public string Name { getset; }
        
public int Age { getset; }
    }

 

clientaccesspolicy.xml

<?xml version="1.0" encoding="utf-8" ?>
<access-policy>
  
<cross-domain-access>
    
<policy>
      
<allow-from http-request-headers="*">
        
<domain uri="*" />
      
</allow-from>
      
<grant-to>
        
<resource path="/" include-subpaths="true"/>
      
</grant-to>
    
</policy>
  
</cross-domain-access>
</access-policy>

 

crossdomain.xml

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
  
<cross-domain-access>
    
<policy>
      
<allow-from http-request-headers="*">
        
<domain uri="*" />
      
</allow-from>
      
<grant-to>
        
<resource path="/" include-subpaths="true"/>
      
</grant-to>
    
</policy>
  
</cross-domain-access>
</access-policy>
