How to Change class property name at runtime in C#?

Let's Say,
public class Customer
{
public int CustId {get; set;}
public string CusName {get; set;}

}

So, during runtime I want to change property name, lets say CustId to "CustomerId" &
CusName to "CustomerName".

What I have tried:

I guess using reflection we can achieve these.

You can't do this, if you explain what you're trying to achieve there might be an alternative such as using a Dictionary or some other structure.

Actually I am implementing file write functionality, in which I got a list having type customer but while display column name to csv file I want "CustomerId" not a "CustId". & If I manipulate these things at the time of writing a file it may cause performance issue because of large record.

Note : While writing a csv file I used Nuget package CsvHelper.

No, reflection is not used to modify the assemblies. What I think would be possible, it to use attributes and pass other name as an attribute. Like

[RuntimeName("CustomerID")]

But you will have to write that attribute yourself.

Why do you want to do this? It makes no sense if you look to how Object orientated programming works

Does the library you're using support attributes on the data items? Like [Description] or [Name] or something like that.

The idea is that you don't change the property names but add an attribute that tells the export code to export a different name in the file.

Based on the comments, you're using CsvHelper[^] to export data to a CSV file, and you want to change the titles of the columns.

There's no need to change the property name to do that. Just set up a class mapping[^]:

C#

public class CustomerMap : CsvClassMap<Customer>
{
    public CustomerMap()
    {
        Map(m => m.CustId).Name("CustomerId");
        Map(m => m.CusName).Name("CustomerName");
    }
}
...
using (var writer = new CsvWriter(...))
{
    writer.Configuration.RegisterClassMap<CustomerMap>();
    writer.WriteRecords(listOfCustomers);
}
