盘锦长颈鹿美语怎么样:InitializeComponent();问题

ASP.NET刚刚新建一个WebServeice启动时候可以运行！！
但是添加一个方法之后代码：
[WebMethod]
public decimal QuerySMBill(string CardNo,int year ,int month)
{
decimal result =0;
string ConnectionString=ConfigurationSettings.AppSettings["ConnectionString"];
SqlConnection conn=new SqlConnection ();
SqlCommand comm=new SqlCommand ();
conn.ConnectionString =ConnectionString;
conn.Open();
comm.Connection =conn;
comm.CommandText ="usp_QuerySMBill";
comm.CommandType=CommandType.StoredProcedure ;
SqlParameter param1=new SqlParameter ("@year",SqlDbType.Int);
param1.Direction =ParameterDirection.Input;
param1.Value =year;
comm.Parameters .Add(param1);
SqlParameter param2=new SqlParameter ("@Month",SqlDbType.Int );
param2.Direction =ParameterDirection.Input ;
param2.Value =month;
comm.Parameters.Add(param2);
SqlParameter param3=new SqlParameter ("@Total",SqlDbType.Decimal ,10);
param3.Scale =2;
param3.Direction =ParameterDirection.Output;
comm.Parameters.Add (param3);
SqlParameter param4=new SqlParameter ("@CardNo",SqlDbType.Char ,11);
param4.Direction=ParameterDirection.Input;
param4.Value =CardNo;
comm.Parameters .Add(param4);
comm.ExecuteNonQuery ();
result=(decimal)param3.Value ;
return result;
}

一运行就会出现一个错误：
名称“InitializeComponent”在类或命名空间“TeleComServices.CustomerInquiryServices”中不存在

请高手帮忙！解决问题的加分！！
