Ensuring that string item is a valid string and not empty in Split?

Question

I have a method like this

public static List<string> ToList(this string str)
{
    return str.Split(',').ToList();
}

I want to know if I can keep the 1-line beauty and also check if the item in the split is actually a string without any whitespaces or a whitespace itself, so basically if its a solid word without and spaces.

ok. so if you check it....and its whitespace, then what? you can check that with linq...but ok...so what then? you have to either remove them or something, and that can be done w/linq too...you just have to add onto your 1 liner chain... — lollmbaowtfidgafgtfoohwtbs

How about this code block?

public static List<string> ToList(this string str)
{
    return str.Split(',').Where(vstr => !string.IsNullOrWhiteSpace(vstr)).Distinct().ToList();
}

Note - The above code has a distinct clause added, which will remove duplicates.

You must use a where statement from LINQ.

public static List<string> ToList(this string str)
{
    return str.Split(',').Where( s=> !string.IsNullOrWhiteSpace(s)).ToList();
}
