Question

I have a class that contains a variable of indeterminate type, which must be overridden at runtime, how can I do this?

Sorry for the disgusting question(
Example:

public class MyClass 
{
     public e_Type TypeValue;
     public (variable of indeterminate type) Value;
}


public enum e_Type
{
    string, int, bool, byte
}

At runtime variable TypeValue should determine the type of variable Value

It sounds like you’re really after generics:

class Foo<T>
{
    public T Value { get; set; };
}

Then you can create instances for different types:

Foo<string> x = new Foo<string>();
x.Value = "fred";

Foo<int> y = new Foo<int>();
y.Value = 10;

This is still fixing the type at compile-time – but when the code using the type is compiled.

var is completely wrong here – var is just used for implicitly typed local variables. In particular, you can’t apply it to fields.

It’s possible that you want dynamic, but it’s not really clear from your question at the moment.
