List item name

[scarm]

Hi,

I have a list which is named:

List<TestList> TestList = new List<TestList>();

I am able to the value from it by using e.g.
string value = TestList[0].ListItem1

Is it possible to make ListItem1 variable?
so something like:

string variable = "ListItem1"
string value = TestList[0].(string)variable

Thanks

In answer - yes, you can do this with reflection.

However you shouldn't - it leads to runtime errors rather than compile-time errors (so they tend to happen infront of users which makes you look like an idiot) as well as being inefficient.

I'd suggest having a switch statement e.g.

string variable = "ListItem1"
string value = null;

switch (variable)
{
    case "ListItem1":
        value = TestList[0].ListItem1;
        break;

    case "ListItem2":
        value = TestList[0].ListItem2;
        break;

    // etc
}

However code like this in my experience is caused by a fault in the overall code design - what is it you're trying to do exactly ? ListItem1/ListItem2 suggests to me that you're trying to hook up a UI in some way. In which case a Dictionary might be a better option.

Thanks for your quick reply,
I understand I have probably chosen the wrong setup.

I want to compare a ListItem to a value.

So something like:

if (TestList[0].(string)variable == "A")
{
}

where (string)variable is "ListItem1" and is chosen from a combobox.
Could also be "ListItem2"
etc.
