I had a co-worker recently ask me what I did to send email from a C# web application. I gave him what worked for me. He made a few adjustments and sent it back to me.  I did request that he send me what he came up with that finally worked for him. I think he did a better job than I so I am going to post it for you to see. Have a look and see how it may fit into your application or project. Improvements are welcome. He ended up writing a class to call from anywhere in the project. It takes the following arguments; from, to, subject, body, attachments, and isBodyHTML boolean.

using System.Net;
using System.Net.Mail;

public class mailer
{
public Boolean sendemail(String strFrom, string strTo, string strSubject, string strBody, string strAttachmentPath, bool IsBodyHTML)
{
Array arrToArray;
char[] splitter = { ';' };
arrToArray = strTo.Split(splitter);
MailMessage mm = new MailMessage();
mm.From = new MailAddress(strFrom);
mm.Subject = strSubject;
mm.Body = strBody+disclaimer;
mm.IsBodyHtml = IsBodyHTML;
//mm.ReplyTo = new MailAddress("replyto@xyz.com");
foreach (string s in arrToArray)
{
mm.To.Add(new MailAddress(s));
}
if (strAttachmentPath != "")
{
try
{
//Add Attachment
Attachment attachFile = new Attachment(strAttachmentPath);
mm.Attachments.Add(attachFile);
}
catch { }
}
SmtpClient smtp = new SmtpClient();
try
{
smtp.Host = "mail.domain.com";
smtp.Port = 25; //Specify your port No;
smtp.Send(mm);
return true;
}
catch
{
mm.Dispose();
smtp = null;
return false;
}
}
}

Thanks Shane!

Hope this helped someone.  Have fun coding and as always, if there are any questions or suggestions, they are welcome.  Thank you.

I know we have all have to use dates at some time or another.  I came across this posting and thought I would list it here for you.  Hope it helps.

DateTime today = DateTime.Today; // just the date

DateTime tomorrow = today.AddDays(1);

DateTime yesterday = today.AddDays(-1);

TimeSpan time = tomorrow – today;

int days = time.Days;

int hours = time.Hours;

int minutes = time.Minutes;

int seconds = time.Seconds;

int milliseconds = time.Milliseconds;

time += new TimeSpan(days, hours, minutes, seconds,

milliseconds);

As always, if there are any questions or suggestions, they are welcome. Thank you.

This will be a short post. I just wanted to display the differences between C# and VB when performing loops.  See below:

VB:

For i As Integer = 10 To 1 Step -1

Console.WriteLine(i)

If i < 5 Then

Exit For

End If

Next

Dim start As Integer = 5

For i As Integer = start To start + 10

Console.WriteLine(i)

Next

Dim str As String

Do

str = Console.ReadLine()

Console.WriteLine(str)

Loop Until str = “”

Do

str = Console.ReadLine().Trim()

If String.IsNullOrEmpty(str) Then

Exit Do

End If

Console.WriteLine(“You typed:{0}”, str)

Loop

Dim names As String() = New String() {“Bob”, “David”}

For Each name As String In names

Console.WriteLine(name)

Next

C#: 

for (int i=0; i<10; i++) {}

while (i<10) { i++; }

do { i++; } while (i<10);

foreach (ListItem item in list.Items) {}

I do not use C# much. Here is some code I found while browsing the Internet that helps to connect to a database:

using System.Data;
using System.Data.SqlClient;
string cs = @"Data Source=.\SQLEXPRESS;" +
string cs = @"Initial Catalog=NamesDB;" +
string cs = @"Integrated Security=True;";
using (SqlConnection con = new SqlConnection(cs)) {
con.Open();
string sql = "INSERT INTO Names(Name) VALUES(@Name)";
// insert a record
SqlCommand cmd1 = new SqlCommand(sql, con);
cmd1.Parameters.Add("@Name", SqlDbType.NVarChar, 100);
cmd1.Parameters["@Name"].Value = "Bob";
cmd1.ExecuteNonQuery();
// insert a second record
cmd1.Parameters["@Name"].Value = "David";
cmd1.ExecuteNonQuery();
// read records
sql = "SELECT * FROM Names";
SqlCommand cmd2 = new SqlCommand(sql, con);
using (SqlDataReader r = cmd2.ExecuteReader()) {
int iName = r.GetOrdinal("Name");
while (r.Read()) {
Console.WriteLine(
r.IsDBNull(iName)?"Null":r.GetString(iName)
);
}
}
// read a single value
sql = "SELECT TOP 1 Name FROM Names";
SqlCommand cmd3 = new SqlCommand(sql, con);
Console.WriteLine(cmd3.ExecuteScalar());
}

Good luck and Happy Coding!

int i = 0;

// convert from a string

int i = int.Parse(“1″);

// convert froma string and don’t throw exceptions

if (int.TryParse(“1″, out i)) {}

i++; // increment by one

i–; // decrement by one

i += 10; // add 10

i -= 10; // subtract 10

i *= 10; // multiply by 10

i /= 10; // divide by 10

i = checked(i*2) // check for over flow

i = unchecked(i*2) // ignore over flow
