Insert to database MVP C#

Question

Hi ....

 

I am trying to insert data to database table but i need it check before insert if the inserted data is Exists in database table iam getting this error :

 

CS0120 An object reference is required for the non-static field, method, or property 'ManageVisitsTypesService.InsertVisitsTypes(int, string, bool, string, int)'

 

I sure this Method is not Static.

 

First i have Stored Procedure:

Create procedure [dbo].[Save_Visits_Types]
@VisitTypeID int output,
@VisitTypeName nvarchar (Max),
@VisitTypeStatus bit,
@VisitTypeNotes nvarchar (Max),
@CreatedBy int
As
BEGIN
SET NOCOUNT ON;
If Exists(SELECT 1 FROM dbo.VisitsTypesTbl WHERE VisitTypeID = @VisitTypeID)
BEGIN
Return -3;
END;
If Exists(SELECT 1 FROM dbo.VisitsTypesTbl WHERE VisitTypeName = @VisitTypeName)
BEGIN
Return -4;
END;
INSERT INTO dbo.VisitsTypesTbl (VisitTypeID, VisitTypeName, VisitTypeStatus, VisitTypeNotes, CreatedDate, CreatedDeviceName)
VALUES (@VisitTypeID, @VisitTypeName, @VisitTypeStatus, @VisitTypeNotes, getdate(), HOST_NAME());
Return -2;
END

Then i have Data Access Layer Which i named DBHelper :

//Method To Insert , Update And Delete From Database
public static bool ExcuteData(string SpName, Action method)
{
using (SqlConnection connection = GetConnectionString())
{
try
{
command = new SqlCommand(SpName, connection);
command.CommandType = CommandType.StoredProcedure;
method.Invoke();
connection.Open();
command.ExecuteNonQuery();
connection.Close();
return true;
}
catch (Exception ex)
{
connection.Close();
Console.WriteLine(ex.Message);
return false;
}
finally
{
connection.Close();
}
}
}

Then i have Created Model Class Which contain :

namespace Team_Manager.Models
{
public class ManageVisitsTypesModel
{
public int VisitTypeID { get; set; }
public string VisitTypeName { get; set; }
public bool VisitTypeStatus { get; set; }
public string VisitTypeNotes { get; set; }
public int CreatedBy { get; set; }
}
}

Then i have created the Service Class which contain the insert Method :

//This Method For Insert Paramerters For Visits Types To Database
public SaveResult InsertVisitsTypesParamerter(int VisitTypeID, string VisitTypeName, bool VisitTypeStatus, string VisitTypeNotes, int CreatedBy, SqlCommand command)
{
var pReturnValue = new SqlParameter("@ReturnValue", SqlDbType.Int) { Direction = ParameterDirection.ReturnValue };
command.Parameters.Add("@VisitTypeID", SqlDbType.Int).Value = VisitTypeID;
command.Parameters.Add("@VisitTypeName", SqlDbType.NVarChar).Value = VisitTypeName;
command.Parameters.Add("@VisitTypeStatus", SqlDbType.Bit).Value = VisitTypeStatus;
command.Parameters.Add("@VisitTypeNotes", SqlDbType.NVarChar).Value = VisitTypeNotes;
command.Parameters.Add("@CreatedBy", SqlDbType.Int).Value = CreatedBy;
switch ((int)pReturnValue.Value)
{
case -2: return SaveResult.Ok;
case -3: return SaveResult.DuplicateId;
case -4: return SaveResult.DuplicateName;
default: return SaveResult.UnknownError;
}
}
//This Method For Insert Visits Types To Database
public bool InsertVisitsTypes(int VisitTypeID, string VisitTypeName, bool VisitTypeStatus, string VisitTypeNotes, int CreatedBy)
{
return ExcuteData("Save_Visits_Types", () => InsertVisitsTypesParamerter(VisitTypeID, VisitTypeName, VisitTypeStatus, VisitTypeNotes, CreatedBy, command));
}

And Presenter Class :

class ManageVisitsTypesPresenter
{
IManageVisitsTypes iManageVisitsTypes;
ManageVisitsTypesModel ManageVisitsTypesModel = new ManageVisitsTypesModel();
public ManageVisitsTypesPresenter(IManageVisitsTypes view)
{
iManageVisitsTypes = view;
}
// Connect Between Model And Interface
private void ConnectManageVisitsTypesModelAndInterface()
{
ManageVisitsTypesModel.VisitTypeID = iManageVisitsTypes.VisitTypeID;
ManageVisitsTypesModel.VisitTypeName = iManageVisitsTypes.VisitTypeName;
ManageVisitsTypesModel.VisitTypeStatus = iManageVisitsTypes.VisitTypeStatus;
ManageVisitsTypesModel.VisitTypeNotes = iManageVisitsTypes.VisitTypeNotes;
ManageVisitsTypesModel.CreatedBy = iManageVisitsTypes.CreatedBy;
}
// Insert Visits Types
public void VisitsTypesInsert()
{
if (iManageVisitsTypes.VisitTypeName == "")
{
iManageVisitsTypes.TheError.SetError(iManageVisitsTypes.TheStatus, "Please Type Visit Type");
return;
}
SaveResult saveResult = ManageVisitsTypesService.InsertVisitsTypes(ManageVisitsTypesModel.VisitTypeID, ManageVisitsTypesModel.VisitTypeName, ManageVisitsTypesModel.VisitTypeStatus, ManageVisitsTypesModel.VisitTypeNotes, ManageVisitsTypesModel.CreatedBy);
if (saveResult == SaveResult.DuplicateId)
{
MessageBox.Show("This ID Type Allready Exists");
}
else if (saveResult == SaveResult.DuplicateName)
{
MessageBox.Show("This Type Name Allready Exists");
}
else
{
ConnectManageVisitsTypesModelAndInterface();
GetActiveVisitsTypes();
AutoNumber();
XtraMessageBox.Show(DevExpress.LookAndFeel.UserLookAndFeel.Default, "Visit Type Saved Successflly ...", "Add Visit Type", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
