Finding the variable name passed to a function

Question

Let me use the following example to explain my question:

public string ExampleFunction(string Variable) {
    return something;
}

string WhatIsMyName = "

GateKiller, what's wrong with my workaround? You could rewrite your function trivially to use it (I've taken the liberty to improve the function on the fly):

static string sMessages(Expression>> aMessages) {
    var messages = aMessages.Compile()();

    if (messages.Count == 0) {
        return "";
    }

    StringBuilder ret = new StringBuilder();
    string sType = ((MemberExpression)aMessages.Body).Member.Name;

    ret.AppendFormat("
", sType);
    foreach (string msg in messages) {
        ret.Append(msg);
        ret.Append("
");
    }
    ret.Append("
");
    return ret.ToString();
}

Call it like this:

var errors = new List() { "Hi", "foo" };
var ret = sMessages(() => errors);
