Issue using switch case statement

I have code like this currently

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data;
using System.Drawing;
using System.ComponentModel;
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Excel;
namespace Excel1
{
    class Program
    {
        static void Main(string[] args)
        //public void ExcelOps()
        {
            //string str;
            Excel.Application xlApp = new Excel.Application();
            Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"D:/WebServiceTemplate.xlsx");
            Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
            Excel.Range xlRange = xlWorksheet.UsedRange;
            int rowCount = xlRange.Rows.Count;
            int colCount = xlRange.Columns.Count;
            int numSheets = xlWorkbook.Sheets.Count;
            //
            // Iterate through the sheets. They are indexed starting at 1.
            //
            for (int sheetNum = 1; sheetNum <=1; sheetNum++)
            {
                Worksheet sheet = (Worksheet)xlWorkbook.Sheets[sheetNum];
                //
                // Take the used range of the sheet. Finally, get an object array of all
                // of the cells in the sheet (their values). 
                //
                object[,] valueArray = (object[,])xlRange.get_Value(XlRangeValueDataType.xlRangeValueDefault);
                //
                // Do something with the data in the array with a custom method.
                //                
                ProcessInput(valueArray);
            }
        }
        public static void ProcessInput()
        {
        }
    }
}

I am trying to do something with the data in the array with a custom method. When I run it, I get an error "Error No overload for method 'ProcessInput' takes 1 arguments"

What is wrong? How do I go ahead and rectify this?

It means that the ProcessInput method is not visible from where you are calling it. Where is it defined? — O. R. Mapper

Where is 'ProcessInput' defined? You are calling it as if it is a member method of your Program. — Ebad Masood

if this is a complete code, the compiler is absolutely right.

You don't have any ProcessInput(..); function definition in this code.

EDIT

Looking on edited post would say that what you missed is declaring your ProcessInput functions like a static

    public static void ProcessInput()
    {
       ....
    }

Now (after the edit to your question) the problem is that you are calling an instance method (ProcessInput) without having an instance of your class Program (Main is a static method).

Mark ProcessInput as static, too, to solve the problem:

public static void ProcessInput()
{
}

Alternatively, create an instance of your Program class and call the method on that:

Program prg = new Program();
prg.ProcessInput();

Try changing to

public static void ProcessInput()
{
}
