c# - One-liner if statements, how to convert this if-else-statement

Total noob here so be gentle. I've looked everywhere and can't seem to find the answer to this. How do I condense the following?

if (expression)
{
    return true;
}
else
{
    return false;
}

I can't get it to work since it's returning something vs. setting something. I've already seen things like this:

somevar = (expression) ? value1 : value2;

Like I said, please be gentle :)

return (expression) ? value1 : value2;

If value1 and value2 are actually true and false like in your example, you may as well just

return expression;
