Delegate CLass Method is not working

[lenniekuah]

Hi Good Friends,
I encounter another problem while trying to use DELEGATE Class method to perform calculation to return the result to the Calling FORM FrmMain.cs

Here are the error message:
Error 1 The left-hand side of an assignment must be a variable, property or indexer

this is the coding that generate the above error
dblTotalAmt=((this.dblLoanAmt*=this.dblInterest)/= 100);

------------------------------------------------
Class Delegate Coding:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharpDelegate
{
 class ClassDelegateCalculate
  {
   //declare the DelegateCalculatonClass
   public delegate double DelegateCalculate(double LoanAmt, double interest);
 
  //declare variables 
  public  double dblLoanAmt;
  public  double dblInterest;
  public  double dblTotalAmt;
 
 //constructor override
 public ClassDelegateCalculate(double Loan, double  YearInt)
 {
    this.dblLoanAmt = Loan;
    this.dblInterest=YearInt;                                    
 }
 
   //class methods - calculate interest on loan amount   
   public  Double propCalculate()
     //return variable back to calling Program
   {                               
    dblTotalAmt = (( this.dblLoanAmt *= this.dblInterest) /= 100);<--- error here    return (dblTotalAmt);  
   }                                    
    }
}

This really doesn't seem to have anything to do with delegates and methods.
Try spliting up your line, it will show you have an extra = sign

this.dblLoanAmt *= this.dblInterest;
dblTotalAmt = ( this.dblLoanAmt/ 100);//note I do not use /=100

Hi Plater,
Regarding your sample coding I am confuse about this:
this.dblLoanAmt *= this.dblInterest;

Where about do you store the result of Multiplication ?

[Plater]

Ahh, so you are just copy/pasting code and don't know what it is doing. I took that line right out of the code you posted.

this.dblLoanAmt *= this.dblInterest;
should be the same as:
this.dblLoanAmt = this.dblLoanAmt * this.dblInterest;
