Hi,

I need to extract a string from another string separated by "," like a .csv
file.
for example I have this string:

String1 = 000,federico,00,439827HGH,1233,FGB,0000,00,000

and from that string i need to extract string "federico" and string "FGB"
and separate then into another 2 strings:

String2 = "federico"
String3 = "FGB"

How this could be done in Visual Basic .NET ????

Thanks and best regards,
Federico

推荐答案

dim criteria as string ="（frederico）|（FGB）"

dim pattern as string ="（^"& criteria&"，？）|（，？"& criterion&"，？）|（，？"

& criteria&"

dim criteria as string = "(frederico)|(FGB)"
dim pattern as string = "(^" & criteria & ",?)|(,?" & criterion & ",?)|(,?"
& criterion & "

）"

dim regExp as new regEx（pattern）

dim match as匹配

dim yourString as string =" 000，federico，00,439827HGH，1233，FGB，0000,00,00 0"

regExp.Matches中的每场比赛（yourString）

console.writeline（match.value）

next


或其他什么东西。

)"

dim match as match
dim yourString as string = "000,federico,00,439827HGH,1233,FGB,0000,00,00 0"
for each match in regExp.Matches(yourString)
console.writeline(match.value)

or something therebouts.

谢谢，但是，也许我以错误的方式解释这一点，因为字符串

总是会有所不同，并且在任何时候都不知道它的价值，唯一的

将知道关于，的立场。人物。


任何想法？

Steve:

Thanks but, maybe I explain this in the wrong way, because the strings
always will be different and will don''t know its value at any time, the only
thing that will know is the position regarding the "," character.

any idea ?

Thanks again...
