Variable.cs
public string[] CcEmails { get; set; }
Mail.cs
EDTO.CcEmails = dr["rsh_ccmail"].ToString().Split(';');
here i got two strings eg. xxxx@gmail.com ; yyy@gmail.com
MailProcess.cs
dataRPT1=get data from sql
EDTO.CcEmails = new string[dataRPT1.Rows.Count];
for (int i = 0; i < dataRPT1.Rows.Count; i++)
{
EDTO.CcEmails[i] = dataRPT1.Rows[i]["email_addr"].ToString();
}
Here i got list of string eg.aaa@gmail.com ...... I am try to add with existing but it add only new values..Anyone could help me..
I find the easiest way of doing this is to create a list, add items to the list, then use string.Join to create the new string.
var items = new List<string>();
for (int i = 0; i < dataRPT1.Rows.Count; i++)
{
items.Add(dataRPT1.Rows[i]["email_addr"].ToString());
}
EDTO.CcEmails = string.Join(";", items);
Update after changed question:
If the type of the CcEmails is an array, the last line could be:
EDTO.CcEmails = items.ToArray();
I tend to use union, although that will remove duplicate entries. But to keep all entries you can use Concat on the array.
var emailString = "me@test.com;you@test.com";
string[] emails = emailString.Split(';');
string[] emailsFromSQL = new string[3];
emailsFromSQL[0] = "everyone@test.com";
emailsFromSQL[1] = "everyone2@test.com";
emailsFromSQL[2] = "everyone2@test.com";
//No Duplicates
var combined = emails.Union(emailsFromSQL).ToArray();
//Duplicates
var allCombined = emails.Concat(emailsFromSQL).ToArray();
