Easier way of writing null or empty?

Question

I\'m sure I\'ve missed something here. With a certain project I need to check if a string is empty or null.

Is there an easier way of writing this?

To avoid null checks you can use ?? operator.

var result = value ?? "";

I often use it as guards to avoid sending in data that I don't want in methods.

JoinStrings(value1 ?? "", value2 ?? "")

It can also be used to avoid unwanted formatting.

string ToString()
{
    return "[" + (value1 ?? 0.0) + ", " + (value2 ?? 0.0) + "]";
}

This can also be used in if statements, it's not so nice but can be handy sometimes.

if (value ?? "" != "") // Not the best example.
{
}
