I want to execute a stored procedure

CREATE PROCEDURE [dbo].[sp_Insert_Donor_Details] 
	-- Add the parameters for the stored procedure here
	@Name nvarchar(50),
	@Address nvarchar(MAX),
	@Phone nchar(10),
	@Pin nchar(10),
	@Email nvarchar(50),
	@DOB nvarchar(9),
	@Ann nvarchar(9),
	@DeathAnn nvarchar(9),
	@Family bit
AS
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;

	INSERT INTO tbl_Donor_Details (Name, [Address], Phone, EmailID, Pincode, DOB, Anniversary, DeathAnniversary, HasFamily)
	VALUES (@Name, @Address, @Phone, @Email, @Pin, @DOB, @Ann, @DeathAnn, @Family)

	SELECT SCOPE_IDENTITY() AS DonorID
END


GO

Here I want to get the DonorID in my code. My c# code to call the stored procedure is:

if (txtName_1.Text != "" || txtName_2.Text != "" || txtName_3.Text != "" || txtName_4.Text != "")
                    family = true;
                var result = GDB.sp_Insert_Donor_Details(txtName.Text, txtAddress.Text, txtPhone.Text,
                    txtEmail.Text, txtPin.Text, txtDOB.Text, txtAnniversary.Text, txtDeathAnniversary.Text, 
                    family).ToList();

Please help me out how can I get result as DonorID (scope identity from the database). Currently I am getting System.Decimal as the value of result.
