非.NET语言调用.NETXMLWebServices返回的数据集合的两个方法

[WebMethod]
public  DataSet GetPersonData()
... {
    DataTable table=new DataTable("Person");        
    table.Columns.Add("Name");
    table.Columns.Add("Gender");
    table.Rows.Add(new string[2]...{"Alice","Female"});
    table.Rows.Add(new string[2]...{"Bob","Male"});
    table.Rows.Add(new string[2]...{"Chris","Male"});
                
    DataSet dataset=new DataSet("PersonTable");
    dataset.Tables.Add(table);
         return dataset;
}
图表1. 返回类型为DataSet的Web Method

图表2. 被格式化成XML的DataSet

[WebMethod]
public  Person[] GetPersons()
{
    Person Alice = new  Person( " Alice " , " Female " );
    Person Bob = new  Person( " Bob " , " Male " );
    Person Chris = new  Person( " Chris " , " Female " );
    Person Dennis = new  Person( " Dennis " , " Male " );

     return   new  Person[]{Alice,Bob,Chris,Dennis};
}

[WebMethod]
public   string  GetPersonTable()
{
    DataTable table = new  DataTable( " Person " );        
    table.Columns.Add( " Name " );
    table.Columns.Add( " Gender " );
    table.Rows.Add( new   string [ 2 ]{ " Alice " , " Female " });
    table.Rows.Add( new   string [ 2 ]{ " Bob " , " Male " });
    table.Rows.Add( new   string [ 2 ]{ " Chris " , " Female " });
    table.Rows.Add( new   string [ 2 ]{ " Dennis " , " Male " });
    table.Rows.Add( new   string [ 2 ]{ " Eric " , " Male " });
    
    DataSet dataset = new  DataSet( " PersonTable " );
    dataset.Tables.Add(table);
    
    System.Text.StringBuilder strbuilder = new  System.Text.StringBuilder();
    StringWriter writer = new  StringWriter(strbuilder);
    dataset.WriteXml(writer,System.Data.XmlWriteMode.IgnoreSchema);
    
     return  strbuilder.ToString();
}
图表3. 用.NET实现的XML Web Services

[Serializable]
public   class  Person
{
     public  Person()
    {
    }

     public  Person( string  name, string  gender)
    {
         this .Name = name;
         this .Gender = gender;
    }

     public   string  Name = "" ;
     public   string  Gender = "" ;
}

xml version="1.0" encoding="utf-8" ?>
