I was wondering if I can add some variables in an array, and access them in a simply way like :
string[] ArrayName = {
string abc;
string varName;
}
//and later access them like:
Console.WriteLine(ArrayName[ab+"c"]);

I think you're just looking for a dictionary:
var ArrayName = new Dictionary<string, string> {
{ "abc", "something" },
{ "varName", "something" },
};
Console.WriteLine(ArrayName["ab"+"c"]);
First Edit
Alternatively, as you may be aware, C# lets you overload operators like the indexer -- so if you wanted to, you could write a class that defines its own special behavior for obj["string"] (returning a member of the same name, or whatever else).
public class IndexableClass
{
private string _abc = "hello world";
public string VarName { get; set; }
public string this[string name]
{
get
{
switch (name)
{
// return known names
case "abc" : return _abc;
// by default, use reflection to check for any named properties
default :
PropertyInfo pi = typeof(IndexableClass).GetProperty(name);
if (pi != null)
{
object value = pi.GetValue(this, null);
if (value is string) return value as string;
else if (value == null) return null;
else return value.ToString();
}
// if all else fails, throw exception
throw new InvalidOperationException("Property " + name + " does not exist!");
}
}
}
}
static void Main()
{
var ArrayName = new IndexableClass();
Console.WriteLine(ArrayName["ab" + "c"]);
}
Second Edit
There are also anonymous types (var ArrayName = new { abc = "something" };), and dynamic types, which you may find useful.

Doesn't the initialization need parentheses?
<string, string>() {

@AustinBrunkhorst actually parentheses are optional when you have the inline initialization

Good to know, wasn't positive on it.
Dictionaryclass.
