Stored procedure Output parameter in c# is returning Empty where as Working fine while Excecuting in SQL
0
I have created a stored procedure where I have a declared an output parameter. It is giving correct result when I execute it in SQL. but I intergrated it in c# code I am getting an Empty object.I am not sure what is the problem.
I have visited so many links but didn't find any appropriate answer.
Here is my C# function Code :-
public bool PreviewAsReviewerButtonEnableDisable(string advId, string userType)
{
bool result = false;
using (RMS_MVCEntities entities = new RMS_MVCEntities())
{
var command = entities.Database.Connection.CreateCommand();
command.CommandText = "[AdvTax].[usp_PreviewAsReviewerButton_Enable_Disable]";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add(new SqlParameter("@AdvID", advId));
command.Parameters.Add(new SqlParameter("@Type", userType));
command.Parameters.Add(new SqlParameter("@EnableDisable", SqlDbType.Bit));
command.Parameters["@EnableDisable"].Direction = ParameterDirection.Output;
entities.Database.Connection.Open();
var reader = command.ExecuteReader();
result = Convert.ToBoolean(command.Parameters["@EnableDisable"].Value);
entities.Database.Connection.Close();
}
return result;
}
Here is my Sql Stored Procedure :-
ALTER PROCEDURE [AdvTax].[usp_PreviewAsReviewerButton_Enable_Disable]
@AdvID nvarchar(20),
@Type nvarchar(20),
@EnableDisable bit output
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
If @Type='CTT Maker'
Begin
Declare @Count int=(select Count(*) from [AdvTax].[AdvTax_Computation] where AdvID=@AdvID and IsActive=1)
If @Count>0
Begin
set @EnableDisable=1
End
Else
Begin
set @EnableDisable=0
End
End
If @Type='CTT Checker'
Begin
Declare @Count1 int=(select Count(*) from [AdvTax].[AdvTax_Computation_Checker]
where AdvID=@AdvID and IsActive=1)
If @Count1>0
Begin
set @EnableDisable=1
End
Else
Begin
set @EnableDisable=0
End
End
END

You can try to assign it directly
var result = (bool)command.ExecuteReader();
Hope this helps.
