One liner for If string is not null or empty else

Question

I usually use something like this for various reasons throughout an application:

if (String.IsNullOrEmpty(strFoo))
{
     FooTextBox.Text = \"0\";
}
else
{
          


        

Answer 1

You can achieve this with pattern matching with the switch expression in C#8/9

FooTextBox.Text = strFoo switch
{
    { Length: >0 } s => s, // If the length of the string is greater than 0 
    _ => "0" // Anything else
};
