Je crée un service Web pour obtenir les détails de l'employé dans l'application client. Pour ce faire, je l'ai suivi les étapes suivantes:Problème de service Web en C# .net
employé propertyclass:
public class EmployeeProperty
{
#region class Members.
private string _employeeid;
private string _employeename;
#endregion
#region class property.
public string EmployeeID
{
get { return _employeeid; }
set { _employeeid = value; }
}
public string EmployeeName
{
get { return _employeename; }
set { _employeename = value; }
}
classe EmployeeDAL:
public DataSet GetEmployeeById(EmployeeProperty employee)
{
SqlConnection conn = new SqlConnection(connStr);
conn.Open();
// building the command
SqlCommand oCommand = new SqlCommand("GetEmployeeById", conn);
oCommand.CommandType = CommandType.StoredProcedure;
// Parameters
SqlParameter paraemployeeId = new SqlParameter();
paraemployeeId.ParameterName = "@employeeId";
paraemployeeId.SqlDbType = SqlDbType.VarChar;
paraemployeeId.Size = 15;
paraemployeeId.Direction = ParameterDirection.Input;
paraemployeeId.Value = employee.EmployeeID;
oCommand.Parameters.Add(paraemployeeId);
// Adapter and DataSet
SqlDataAdapter oAdapter = new SqlDataAdapter();
oAdapter.SelectCommand = oCommand;
DataSet oDataSet = new DataSet();
try
{
oAdapter.Fill(oDataSet, "Employee");
if (oDataSet.Tables[0].Rows.Count > 0)
{
employee.EmployeeID = oDataSet.Tables[0].Rows[0]["Emp_ID"].ToString();
employee.EmployeeName = oDataSet.Tables[0].Rows[0]["Emp_Name"].ToString();
return oDataSet;
}
else
{
throw new ApplicationException("Business object not found.");
}
}
catch (Exception oException)
{
throw;
}
finally
{
conn.Close();
}
}
WebserviceClass:
public class EmployeeWebService : System.Web.Services.WebService
{
[Webmethod]
public DataSet GetEmployeeById(EmployeeProperty employee)
{
DataSet ds = new DataSet();
EmployeeDAL empdal=new EmployeeDAL();
return empdal.GetEmployeeById(employee);
}
}
De l'application client:
webservice .EmployeeWebService empweb = new webservice .EmployeeWebService();
EmployeeProperty empproperty = new EmployeeProperty();
string empid = Txtempid.Text;
empproperty.EmpID = empid;
empweb.GetEmployeeById(empproperty);
Txtempid.Text = empproperty.EmployeeID;
Txtempname.Text = empproperty.EmployeeName;
....like this other values should display…..but not displaying the employee name in the text box its showing empty value...
What i done is correct????pls help its not working...how can i achieve it.
Ok, vous voulez dire ds = empweb.GetEmployeeById (empproperty); alors comment peupler le membre de la classe employeeproperty ici..par exemple pour afficher empname txtempname.text = ds.EmpName .... comment puis-je faire cela ??? – sain
Vous devrez écrire le code pour cela. – leppie
