Hi,

Q1
If you want to spilt string by number of character, perhaps you should use Substring method as the following.

str.Substring(0,3) returns 123
str.Substring(3) returns 456

Q2
Can you try Split method with StringSplitOptions.RemoveEmptyEntries as the following.

newStr.Split({" "c},StringSplitOptions.RemoveEmptyEntries)(3) returns 8.00

Hi,

System.Text.RegularExpressions.Regex.Match(str,"^.{3}").Value returns 123.

System.Text.RegularExpressions.Regex.Match(str,"(?<=^.{3}).*").Value returns 456.

for question 2 i want “morning” too.

str.Split({" "c},StringSplitOptions.RemoveEmptyEntries)(1)

For Q1, I would rather rely on String.Format or ToString with culture aware formatting or use invariant culture as describe in SO answer inked below. This can handle number with any count of digits and will format decimal “point” if needed too.

For Q2, you can splt on multiple spaces (if I understood) with a regex:

result = System.Text.RegularExpressions.Regex.Split(myText, "\s+")
