remove empty string from array vb.net
提问by Dman
I am trying to get each sentence from my rtextboxinto an array. However, when I use .splitmethod, it gives me empty spaces as part of the array.
我试图将我的每个句子rtextbox放入一个数组中。但是，当我使用.split方法时，它给了我空格作为数组的一部分。
How can I either remove the empty ones or not have them come into the array in the first place?
我怎样才能删除空的或不让它们首先进入数组？
Dim senArray() = RTextBox.Text.Split(New String() {"."}, StringSplitOptions.RemoveEmptyEntries)
Thank you!
谢谢！

You can use a linq Whereexpression to remove the whitespace entries:
您可以使用linqWhere表达式来删除空格条目：
Dim senArray() = RTextBox.Text.Split(
New String() {"."}, StringSplitOptions.RemoveEmptyEntries
).Where(
Function(s) Not String.IsNullOrWhitespace(s)
).ToArray()
