Error in C#: The name 'Parameter' does not exist in the current context"

[hithere8]

I was following the AU iLogic sample (AU Box & AU Shutter Assembly) to migrate some vb.net code to C# as below, however I got the error "The name 'Parameter' does not exist in the current context" as commented in the following code:

using Autodesk.iLogic.Interfaces;
using TempPlate.Utilities;

namespace TempWork
{
    public partial class TempPlate : Form
    {
        public IParamDynamic Parameter = null ;
        public IMultiValueParam MultiValue = null;
        public ILowLevelSupport iLogicVb = null;

        public TempPlate()
        {
            InitializeComponent();
        }
        
        private void TempPlate_Load(object sender, EventArgs e)
        {
            Parameter("Capacity") = 100;  //Error: The name 'Parameter' does not exist in the current context"
            
            tbxCapacity.Text = Parameter("Capacity");         
        }        
    }
}

 Can somebody help me out? Thanks a lot!

Having done some research, and found my mistake to share as below:

Parameter("Capacity") = 100;

Should be corrected as below:

Parameter["Capacity"] = 100;
