如何检测结尾有空格的单词（Regex - C#）

Question

I have created this Regex Pattern (?=[Ss]table[:])(.*) , which "detect" these words:

Stable       <--- Here is one space at the end
stable       <--- Here is one space at the end
Stable:
stable:

The Patter does not detect these words which are without space at the end:

Stable
stable

What should I change to detect and these two Words!

Answer 1

You can use this:

 (?=[Ss]table([ :]|$))(.*)

Al I have changed is:

([ :]|$)

That will look ahead for a space, a colon OR end of line - assuming you use 'multiline' option.

Answer 2

When you add this in string, for examle with name str:

string str= "Stable";
            if (str[str.Length - 1] == ' ')
            {
                your block of code;
            }
