How to map your parameters correctly in wpf using c#?

Hi Team

I am experience this problem, but i am using the correct parameters. I want to get latest batchNumber sequentially so that when the windows application is opened. There should be that number and should increment every time user open the screen.

USE [Adroit_Batch_Suite]
GO

/****** Object:  StoredProcedure [dbo].[spGetPremixSheet]    Script Date: 2024/07/23 13:22:58 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[spGetPremixSheet]
    @procOption NVARCHAR(50),
    @Batch INT = NULL,
    @DateCaptured DATE = NULL,
    @Code NVARCHAR(50) = NULL,
    @Phase NVARCHAR(100) = NULL,
    @Quantity DECIMAL(18, 2) = NULL,
    @Comments NVARCHAR(MAX) = NULL,
    @PrintedBarCodes INT,
    @UnusedBarcodes INT,
	@UsedBarCodes INT,
    @PrintedVar INT,
    @UserVar INT

    SET NOCOUNT ON;

    IF @procOption = 'All'
    BEGIN
        SELECT Batch, DateCaptured, Code, Phase, Quantity, Comments, PrintedBarCodes, UnusedBarcodes, UsedBarCodes,PrintedVar, UserVar
        FROM [dbo].[Adr_Batch_PremixControl]
    END
    ELSE IF @procOption = 'PK'
    BEGIN
        SELECT Batch, DateCaptured, Code, Phase, Quantity, Comments, PrintedBarCodes, UnusedBarcodes, UsedBarCodes,PrintedVar, UserVar 
        FROM [dbo].[Adr_Batch_PremixControl] 
        WHERE Batch = @Batch;
    END
    ELSE IF @procOption = 'Date'

        WHERE DateCaptured = @DateCaptured;
    END
    ELSE IF @procOption = 'LatestBatchNumber'
