I am trying to split at every space " ", but it will not let me remove empty entries and then find the length, but it is treated as a syntax error.
My code:
TextBox1.Text.Split(" ", StringSplitOptions.RemoveEmptyEntries).Length
What am I doing wrong?

Method #1: Using remove() This particular method is quite naive and not recommended use, but is indeed a method to perform this task. remove() generally removes the first occurrence of an empty string and we keep iterating this process until no empty string is found in list.
The split() method does not change the value of the original string. If the delimiter is an empty string, the split() method will return an array of elements, one element for each character of string. If you specify an empty string for string, the split() method will return an empty string and not an array of strings.
To split the sentences by comma, use split(). For removing surrounding spaces, use trim().
To split a string and trim the surrounding spaces: Call the split() method on the string. Call the map() method to iterate over the array. On each iteration, call the trim() method on the string to remove the surrounding spaces.
Well, the first parameter to the Split function needs to be an array of strings or characters. Try:
TextBox1.Text.Split(New String() {" "}, StringSplitOptions.RemoveEmptyEntries).Length
You might not have noticed this before when you didn't specify the 2nd parameter. This is because the Split method has an overload which takes in a ParamArray. This means that calls to Split("string 1", "string 2", "etc") auto-magically get converted into a call to Split(New String() {"string 1", "string 2", "etc"})

Try:
TextBox1.Text.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries).Length
