Convert variable to a string of it's name

[dgerdner]

Let's say I have:

string FirstName = "JOHN"

I'd like to set another string to the variable's name, "FirstName". Is there a c# method for this?

So you want to address the variable via a name?

Put that variable into a Hashtable (key/value pair) and address it that way.

Hashtable varhash = new Hashtable();

varhash.Add("FirstName", FirstName);

Then retrieve the variable via:

string firstname = (string)varhash["FirstName"];

Also, if you need the variable's name to be a string somewhere else, you could also use reflection.

Well, ultimately what I'd like to accomplish is to avoid using the variable name in quotes. As some background, I find myself having to bind a lot of variables to textboxes on my forms, so I keep repeating code such as:

txtBox1.DataBindings.Add("Text", myTable, "MyColumn");

The problem here is that this can compile clean even if "MyColumn" is not spelled correctly, so the error is not discovered until run time. I'd rather be able to creating a binding method of my own, to which I can parse the variable to its name:

private void BindText(TextBox tb, String MyTable.MyColumn)
{
string s1 = getthecolumnname(MyTable.MyColumn)
tb.DataBindings.Add("Text", MyTable, s2)
}

This way if it compiles clean I know it's good.

Somebody else mentioned this, but I have only used reflection once before and don't know where to look for this particular item.

You'd have to do a bit of thinking and reworking, but this link will give you access to what you need to do.
