我是靠谱客的博主要减肥皮卡丘，最近开发中收集的这篇文章主要介绍flex调用webservice中的自定义类的方法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

 
public class ReturnResult 
{ 
public int curIndex { get; set; } 
public DataTable idxList { get; set; } 
} 
//测试数据库连接 
[WebMethod(Description = "！！！测试数据库连接,链接字符串在web.config中")] 
public bool conectDB() 
{ 
strCon = ConfigurationSettings.AppSettings["sqlConDuke"]; 
conn = new SqlConnection(strCon); 
try 
{ 
conn.Open(); 
return true; 
} 
catch (Exception) 
{ 
return false; 
} 
finally 
{ 
conn.Close(); 
} 
} 

复制代码代码如下:

 
[WebMethod(Description = "根据 <b>照片名</b> 获得详细数据(DataTable)，strTb,eg:PanView;strImgName,eg:20131019072740-0000150")] 
public DataTable getInfoByImgName(string strTb, string strImgName) 
{ 
bool ifCon = conectDB(); 
if (ifCon) 
{ 
string sql_BfCar = "SELECT * FROM dbo." + strTb + " where ImageName LIKE '%" + strImgName + "%'"; 
da = new SqlDataAdapter(sql_BfCar, conn); 
myds = new DataSet(); 
da.Fill(myds); 
return myds.Tables[0]; 
} 
else 
{ 
return null; 
} 
} 


[WebMethod(Description = "根据 <b>照片名</b> 获得所在Link的所有数据(ReturnResult)，strTb,eg:PanView;strImgName,eg:20131019072740-0000150")] 
public ReturnResult getLinkDTByImgName(string strTb, string strImgName) 
{ 
ReturnResult returnResult = new ReturnResult(); 
bool ifCon = conectDB(); 
if (ifCon) 
{ 
returnResult.curIndex = Convert.ToInt32(getInfoByImgName(strTb, strImgName).Rows[0][0]); 
string strLinkGuid = getInfoByImgName(strTb, strImgName).Rows[0][1].ToString(); 
string sql_BfCar = "SELECT * FROM dbo." + strTb + " where LinkGuid LIKE '%" + strLinkGuid + "%'"; 
da = new SqlDataAdapter(sql_BfCar, conn); 
myds = new DataSet(); 
da.Fill(myds); 
returnResult.idxList = myds.Tables[0]; 
return returnResult; 
} 
else 
{ 
return null; 
} 
} 

Flex代码：

复制代码代码如下:
