1. A text box for file name
2. A button named as "Segregate"
3. A two column list box ("Word", "Times")
4. Pressing the button should read the file contents and find out each word repeats how many times and display in the list box

I have a strings such as: s = "asd;# qwe;# zxc".

I'm splitting it to array as follow:
a = s.Split(new[] { ";#" });

But it is returns me an array without leading spaces:
"asd", "qwe", "zxc".

How can I easily fix this behavior?

Thank you!

I have a problem to compare 2 or more addresses. As you may know, user always write down their address without using fixed format. For example:

People from Microsoft wrote:
People1:
Microsoft Corporation One Microsoft Way Redmond, WA 98052-6399 USA
People2:
Microsoft Corp. One Microsoft Way Redmond, WA 98052 6399 USA

People4:

RG 14/2FN
People5:
Vodafone Limited, The Connection, Newbury Berkshire
RG-14 2FN

I want system can recognized those 5 addresses as 2 addresses only.

If anyone know the algorithm or anything that might help, please inform me. Thx. ^^

Could provide some code where you are encountering a problem ??

this is missing from the for loop

"if (H.IndexOf(needles[i]) >= 0)"

static bool NinH(string N, string sep, string H)
{
bool ret = false;
string[] s = { sep };
string[] needles = N.Split(s,StringSplitOptions.RemoveEmptyEntries);
for (int i = 0; i = 0)
{
ret = true;
break;
}
}
return ret;
}

Trying to find any of the needles in the haystack. Is there a better way?

NinH("one*two","*","two") <= true
NinH("one*two","*","bucklemyshoe") <= false
NinH("one*two","*","bucklemyoneshoe") <= true
NinH("one*two","*","three*two*one") <= true

static bool NinH(string N, string sep, string H)
{
bool ret = false;
string[] s = { sep };
string[] needles = N.Split(s,StringSplitOptions.RemoveEmptyEntries);
for (int i = 0; i = 0)
{
ret = true;
break;
}
}
return ret;
}
