Hello.

I am trying to do a substring or something like that to extract the middle
portion of a string.

12345 TEST FACILITY 1_Letter 1A
12346 TEST FACILITY 2_Letter 1A

I would like to be able to extract the part after the number and before the
_.

TEST FACILITY 1
TEST FACILITY 2

I am new to C# and still learning, so any help is greatly appreciated.

Rhonda,

Do you know that the number always comes first, and has a space after
it? If so, I would get the index of the first space, and the first
underscore, and then get the substring using those two indexes, like this:

// Assuming str has your string, you could do:
// The index of the space.
int spaceIndex = str.IndexOf(' ');
int ulIndex = str.IndexOf('_');

// Get the substring based on the indexes.
subStr = str.Substring(str.IndexOf(' ') + 1, ulIndex - spaceIndex - 1);

This assumes there is always a single space before the beginning of the
section you want to get, and an underscore immediately following it.

Hope this helps.
 
Nicholas,
Yes there is always a 5 digit number first in my situation. I will try
this. Thanks for the quick response.

Rhonda,

If you know there is always a five digit number, followed by a space,
you can reduce this code to:

// Assuming str has your string, you could do:
// The index of the space.
int ulIndex = str.IndexOf('_');

// Get the substring based on the indexes.
subStr = str.Substring(6, ulIndex - 6);
