Is it possible to concreate variable in c# [duplicate]

Question

I have some variables and there results which are going into database.

For example

        float[] qty1;
        Quote quote = new Quote();
        quote.qty1 = qty1[0];
        quote.qty2 = qty1[1];
        quote.qty3 = qty1[2];
        quote.qty4 = qty1[3];

I try to make this process more dynamic

           for (int i = 0; i <= 3; i++)
            {
            
            quote.qtyi = qty1[i];
            }

please help me how i can use quote.qtyi and value of i, so it will read quote.qty1, quote.qty2, quote.qty3, quote.qty4

maybe Quote.qtyx should also be an array, as qtyx is? That would be the best solutuon — MakePeaceGreatAgain

@HimBromBeere Yup, though I suspect Quote may be a DB entity given the first sentence. — DavidG

Use reflection:

for (int i = 0; i <= 3; i++)
        {
        
        quote.GetType().GetProperty("qty"+i).SetValue(quote,qt1[i]);

        }

quote.getType().getProperty("qty"+i) -> Gets the property called "qty"+i from the object "quote".

.setValue(quote,qt1[i]) -> sets the value "qt1[i]" to the property (if she exists) of the object "quote".

My first answer had TYPOS, now it's compilable

Code-only answers are particularly unhelpful. Explain what you did and why, also list potential issues (e.g. performance of using reflection)

in particula when they don't even compile

Already edited, had some typos now it should work
