whats the best way to do this?

[Steve]

I have to create 2 strings and then parse one string out to save the data
into the database.

My first string looks like this:

Jo***************@yahoo.com,Gr***********@aol.com, Ke************@gmail.com,

I then need to parse out that string to seperate them by the commas so I see
this
Jo***************@yahoo.com
Gr***********@aol.com
Ke************@gmail.com
I then need to parse out that string so I get
John
Greg
Kelly

Smith
Henry
Smith

so I can save each value to the database, what is the best way to do this?
The stored procedure I'm calling is already parsing strings by the comma, so
would it be easier to just parse out the large string in code and pass the
smaller string with the pipe (|) and make a change to the proc to parse the
values by the (|) or should I do all of this in my C# code? If the C# way,
how would that be done? I'm able to get this string format
(Jo***************@yahoo.com) but when I try to parse it out, I' get errors
(Index was outside the bounds of the array)

Hi Steve,

SJ****************@yahoo.com,Gr***********@aol.com ,Kelly|Smith|ks@gmai

The <string>.Split(<separator>) method can be helpful.

I am currently doing that but when I split the first string by the comma(,)
its fine, its the second string Jo***************@yahoo.com thats giving me
a fit.

when i do this:

String[] names= ViewState["custnames"].ToString().Split('|');
foreach (String n in names)
{
String[] u = n.ToString().Split('|');
Response.Write(u[0]);
Response.Write(u[1]);
}

I'm getting this error:
Index was outside the bounds of the array, but if I do this
String[] names= ViewState["custnames"].ToString().Split('|');
foreach (String n in names)
{
String[] u = n.ToString().Split('|');
Response.Write(u[0]);
}

I can see the first name in the string with no problem. So am I missing
something or doing something wrong in the sytnax?

Hi Steve,

Probably the exception occurs in that piece of code:
SResponse.Write(u[1]);

You should check the boundaries.
Anyway, you can try to analyse that input string is correct, for doing this
change your code to something like code below:

foreach (String n in names)
{
foreach(String justForTest in n.ToString().Split('|'))
{ Response.WriteLine(justForTest); }
Response.WriteLine("-");
}

sure:

code:
main string:

String[] users= ViewState["Stuff"].ToString().Split(',');

which returns this:
Jo***************@yahoo.com,

then I loop through that string;
foreach (string s in users)
{
string[] s= strRecord.Split('|');

strFirstName = s[0];
strLastName = s[1];
strEmail = s[2];
}
Response.Write(strFirstName + " " + strLastName + " " +

and I get this error:

strLastName = astrElements[1];

Hi Steve,

SJ****************@yahoo.com,Gr***********@aol.com ,Ke************@gmail.com,
Yes, indeed. Because you have the comma at the end of the string and it is
an empty string. You even can split it by '|' but it will be still empty.
So when you try to access it by indexer an exception will be thrown.

So, you should do these:
1. Set up a boundary checks to be sure that length of the array is enough
for access by indexer
2. Bring you string to appropriate format (use Trim methods for cutting or
such) or check that string can be splitted or was splitted correctly.

Hopefully it helps

Hi, Steve.

For that string, this works for me:

<%@ Page Language="C#" %>
<script runat="server">
void Page_Load(Object obj, EventArgs e)
{
string strRaw = "Jo***************@yahoo.com";
string[] astrElements = strRaw.Split('|');

string strFirstName = astrElements[0];
string strLastName = astrElements[1];
string strEmail = astrElements[2];

lblFirstName.Text = strFirstName;
lblLastName.Text = strLastName;
lblEmail.Text = strEmail;

}
</script>
<html>
<body>
<asp:Label ID="lblFirstName" Runat="server" Text=""></asp:Label><br />
<asp:Label ID="lblLastName" Runat="server" Text=""></asp:Label><br />
<asp:Label ID="lblEmail" Runat="server" Text=""></asp:Label><br />

Hi Steve,

See ending comma. It gives you 4 string and the 4th is empty. You can prevent
it by checking (as I mentioned before) but if it's an incorrect format it
may be better to thrown your own exception to certainly define them.

That simply isn't possible! There aren't even 80 letters in that string,
never mind 80 elements!

Are you following the method I showed you?

Specifically, you need first to split the string by the comma to give an
array of strings for each record.

Then you need to split each record by the pipe symbol to give an array of
individual elements.

I don't think you're doing that...

Yes, that's very true.

What I normally do is trim the string by the split character first

that, but we're starting to run out of options here!

You will do, because C# is case-sensitive. Try this instead:
string[] userDetails = temp.Trim(',').Split(',');

re:

To get around that, after :

string[] astrElements = strRecord.Split('|');

....iterate through the array :

Response.Write(astrElements[0].ToString() + "<br />" );
Response.Write(astrElements[1].ToString() + "<br />" );
Response.Write(astrElements[2].ToString() + "<br />" );

You can also resplit astrElements[i] and parse the individual records.

<script runat="server">
void Page_Load(Object obj, EventArgs e)
{
string temp = "Jo***************@yahoo.com,Gr***********@aol.com ,Ke************@gmail.com";

string[] userDetails = temp.Split(',');

foreach (string strRecord in userDetails)

Response.Write(astrElements[0].ToString() + "<br />" );
Response.Write (astrElements[1].ToString() + "<br />" );
Response.Write (astrElements[2].ToString() + "<br />" );
}
}
</script>
<html>
<body>
</body>
</html>

----------------

You can also resplit astrElements[i] on the pipe for the individual FirstName, LastName, Email items.
