数据库有一个Person表，那么，我们做一个person实体。在webservice里面写一个发布方法，发布一个查询方法，可能查询结果有很多个Person，所以应该返回一个数组，问题在于，数组不定长，所以应该使用ArrayList做一下中转，之后调用toArray()方法变成Person[],即return (Person[])result.toArray(typeof(person)).
代码如下：
Person.cs
using
System;
using
System.Data;
using
System.Configuration;
using
System.Web;
using
System.Web.Security;
using
System.Web.UI;
using
System.Web.UI.WebControls;
using
System.Web.UI.WebControls.WebParts;
using
System.Web.UI.HtmlControls;
/**/
/// <summary>
/// Person 的摘要说明
/// </summary>
public
class
Person
...
{
private int _personID;
public int PersonID
...{
get
...{
return this._personID;
}
set
...{
this._personID = value;
}
}
private string _name;
public string Name
...{
get
...{
return this._name;
}
set
...{
this._name = value;
}
}
private string _birthday;
public string Birthday
...{
get
...{
return this._birthday;
}
set
...{
this._birthday = value;
}
}
public Person()
...{
}
public Person(string pname,string pbirthday)
...{
this._name = pname;
this._birthday = pbirthday;
}
public Person(DaTarow record)
...{
this._personID = Convert.ToInt16(record["personID"]);
this._name = record["name"].ToString();
this._birthday = record["birthday"].ToString();
}
}
Service.cs
using
System;
using

using

public const string ConnString = @"Data Source=.sqlEXPRESS;AttachDbFilename=C:Documents and SettingszhouluMy DocumentsVisual Studio 2005WebSiteswsApp_DataFamily.mdf;Integrated Security=True;User Instance=True";
public Service () ...{
//如果使用设计的组件，请取消注释以下行

return "Hello World";

using(sqlConnection conn = new sqlConnection(ConnString))
using (sqlCommand dataCommand = new sqlCommand("dbo.findbyname", conn))

//dataCommand.Parameters.Add("@name", name);
dataCommand.CommandType = CommandType.StoredProcedure;
dataCommand.Parameters.AddWithValue("@name", Name);
sqlDataAdapter dataAdapter = new sqlDataAdapter(dataCommand);
DataTable data = new DataTable();
dataAdapter.Fill(data);
for (int i = 0; i < data.Rows.Count; i++)
...{
result.Add(new Person(data.Rows[i]));
}
}
return (Person[])result.ToArray(typeof(Person));/**////////////问题所在
}
}
