flex调用webservice中的自定义类的方法

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;
}
}
