FaultException未处理 [英] FaultException was unhandled

问题描述

我是WP7和Web服务的新手。我在WP7中创建了一个登录页面并创建了一个

Web服务。我需要通过Web服务在访问数据库中存储用户详细信息。我成功地在WP7中使用了Web服务，但是在referance.cs文件中运行时'FaultException未处理'时显示错误。

App_code / Services.cs（webservice code）：

 [WebMethod] 
  public   string  userDetail（ int  id， string  uname， string  pwd，< span class =code-keyword> int  age， string  gender， string  place，  string  country）
 {
 OleDbConnection con; 
 OleDbCommand cmd; 
 con =  new  OleDbConnection（  Provider = Microsoft.ACE.OLEDB.12.0;数据源= C：\\Users \\Amma \\Documents\\UserDetail.accdb）; 
 con.Open（）; 
 cmd =  new  OleDbCommand（  insert into登录（id，uname，pwd，年龄，性别，地点，国家）值（？，？，？，？，？，？，？），con）; 
 cmd.Parameters.Add（ ？，id）; 
 cmd.Parameters.Add（ ？，uname）; 
 cmd.Parameters.Add（ ？，pwd）; 
 cmd.Parameters.Add（ ？，年龄）; 
 cmd.Parameters.Add（ ？，性别）; 
 cmd.Parameters.Add（ ？，place）; 
 cmd.Parameters.Add（ ？，country）; 
 cmd.ExecuteNonQuery（）; 
 con.Close（）; 
  return  uname; 
} 

MainPage.xaml.cs（WP7）

  string  name，pwd，gender，place，country; 
  int  age，id =  0 ; 
  private   void  BtnRegister_Click（ object  sender，RoutedEventArgs e）
 {
 ServiceReference1.ServiceSoapClient ws =  new  ServiceReference1.ServiceSoapClient（）; 
 ws.userDetailCompleted + =  new  EventHandler< userDetailCompletedEventArgs>（ws_userDetailCompletd）; 
 
 ws.userDetailAsync（id，name，pwd，age，gender，place，country）; 
} 
  void  ws_userDetailCompletd（ object  sender，userDetailCompletedEventArgs e）
 {
 id = Convert.ToInt32（textBoxId.Text）; 
 pwd = Convert.ToString（textBoxPwd.Text）; 
 name = Convert.ToString（textBoxName.Text）; 
 age = Convert.ToInt32（textBoxAge.Text）; 
 
  if （radioBtnMale.IsChecked ==  true ）
 { 
 gender =  男性; 
} 
  else  
 gender =  女性 ; 
 place = Convert.ToString（textBoxPlace.Text）; 
 country = Convert.ToString（textBoxCountry.Text）; 
 MessageBox.Show（ 已成功注册）; 
} 

referance.cs

  public  Test.ServiceReference1。 userDetailResponse EnduserDetail（System.IAsyncResult result）{
  object  [] _args =  new   object  [ 0 ]; 
 Test.ServiceReference1.userDetailResponse _result =（（Test.ServiceReference1.userDetailResponse）（ base  .EndInvoke（  userDetail，_ args，result）））; 
  return  _result; 
} 

有人请帮助我。谢谢。

解决方案

你需要 catch 异常并处理它。请参阅 http://msdn.microsoft.com/en- us / library / system.servicemodel.faultexception（v = vs.110）.aspx [ ^ ]。

我更改了其他语句，但我无法更改为Int32.TryParse。它抛出了一个错误。 没有重载方法'TryParse'需要1个参数。



我的代码：

age = Int32.TryParse（textboxAge.text）;

I'm new to both WP7 and web service. I created one login page in WP7 and created one
web service.I need to store user detail in access databse through web service. I successfully consumed web service in WP7 but it show error during runtime 'FaultException was unhandled' in the referance.cs file.
App_code/Services.cs (webservice code):

[WebMethod]
    public string userDetail(int id, string uname, string pwd, int age, string gender, string place, string country)
    {       
        OleDbConnection con;
        OleDbCommand cmd;
        con = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\Amma\\Documents\\UserDetail.accdb");
        con.Open();
        cmd = new OleDbCommand("insert into login(id,uname,pwd,age,gender,place,country)values(?,?,?,?,?,?,?)", con);
        cmd.Parameters.Add("?", id);
        cmd.Parameters.Add("?",uname);
        cmd.Parameters.Add("?", pwd);
        cmd.Parameters.Add("?", age);
        cmd.Parameters.Add("?", gender);
        cmd.Parameters.Add("?", place);
        cmd.Parameters.Add("?", country);
        cmd.ExecuteNonQuery();
        con.Close();
        return uname;
    }

MainPage.xaml.cs (WP7)

string name, pwd, gender, place, country;
        int age, id = 0;
        private void BtnRegister_Click(object sender, RoutedEventArgs e)
        {
            ServiceReference1.ServiceSoapClient ws = new ServiceReference1.ServiceSoapClient();
            ws.userDetailCompleted += new EventHandler<userDetailCompletedEventArgs>(ws_userDetailCompletd);

            ws.userDetailAsync(id, name, pwd, age, gender, place, country);
        }
        void ws_userDetailCompletd(object sender,userDetailCompletedEventArgs e)
        {
            id = Convert.ToInt32(textBoxId.Text);
                   pwd = Convert.ToString(textBoxPwd.Text);
                   name = Convert.ToString(textBoxName.Text);
                   age = Convert.ToInt32(textBoxAge.Text);
          
                   if (radioBtnMale.IsChecked == true)
                   {
                       gender = "Male";
                   }
                   else
                       gender = "Female";
                   place = Convert.ToString(textBoxPlace.Text);
                   country = Convert.ToString(textBoxCountry.Text);          
                   MessageBox.Show("successfully Registered");
        }

referance.cs

public Test.ServiceReference1.userDetailResponse EnduserDetail(System.IAsyncResult result) {
                object[] _args = new object[0];
                Test.ServiceReference1.userDetailResponse _result = ((Test.ServiceReference1.userDetailResponse)(base.EndInvoke("userDetail", _args, result)));
                return _result;
            }

Someone pls help me. thanks.

解决方案

You need to catch the exception and deal with it. See http://msdn.microsoft.com/en-us/library/system.servicemodel.faultexception(v=vs.110).aspx[^].

I changed other statements but i can't change to Int32.TryParse. It thrown an error. "No overload for method 'TryParse' takes 1 arguments.

my code:
age=Int32.TryParse(textboxAge.text);
