I need to put an adress into a appointment. The address is constructed out of several variables. Of course I also need some newlines. But "\n" doesnt result in an new line when i open the appointment in outlook.
Ok here is code snippet:
string address = name + "\n" + strasse + "\n" + plz.ToString() + " " + ort;
if ( telefon != "") {
address = address + "\nTelefon:: " + telefon;
}
if ( natel != "") {
address = address + "\nNatel: " + natel;
}
if ( mail != "") {
address = address + "\nE-Mail: " +mail;
}
Nothing special. The Problem is when i write this to the body of an appointment, then there aren't any actual newlines.
Its pretty hard to diagnose this without seeing at least an example of the string you are passing, but one thing that I tend to do in my C# code is to use the constant:
Environment.NewLine
Or I use the StringBuilder class with the AppendLine() call to add a newline.
Edit: Based on your code snippet, I would write it this way (it will be more performant as well). With your snippet, lots of strings are being allocated (because strings are immutable). The recommended approach in this case is to use StringBuilder.
StringBuilder address = new StringBuilder();
address.AppendLine(name);
address.AppendLine(strasse);
address.Append(plz.ToString()); // This may not be neccessary depending on the type of plz, StringBuilder has overloads that will convert base types to string for you
address.Append(" ");
address.Append(ort);
if (!string.IsNullOrEmpty(telefon))
{
address.AppendLine();
address.Append("Telefon:: ");
address.Append(telefon);
}
if (!string.IsNullOfEmpty(natel))
{
address.AppendLine();
address.Append("Natel: ");
address.Append(natel);
}
if (!string.IsNullOrEmpty(mail))
{
address.AppendLine();
address.Append("E-Mail: ");
address.Append(mail);
}
return address.ToString();
Note: If you are using .Net 4.0 you can use string.IsNullOrWhitespace instead of IsNullOrEmpty to check for not just an empty string, but one that contains only whitespace.
Edit 2 - Based on your answer of needing <br /> tags instead of newlines.
const string newLine = " <br /> ";
StringBuilder address = new StringBuilder();
address.Append(name);
address.Append(newLine);
address.Append(strasse);
address.Append(newLine);
address.Append(plz.ToString()); // This may not be neccessary depending on the type of plz, StringBuilder has overloads that will convert base types to string for you
address.Append(" ");
address.Append(ort);
if (!string.IsNullOrEmpty(telefon))
{
address.Append(newLine);
address.Append("Telefon:: ");
address.Append(telefon);
}
if (!string.IsNullOfEmpty(natel))
{
address.Append(newLine);
address.Append("Natel: ");
address.Append(natel);
}
if (!string.IsNullOrEmpty(mail))
{
address.Append(newLine);
address.Append("E-Mail: ");
address.Append(mail);
}
return address.ToString();
Ok i got it now. I found out that appointments are stored in html format.
So i tried to use the html entity for \r\n, .That didn't work. I finally solved the problem by using the br tag
While you're absolutely correct about using <br/>, newline is not the only thing Exchange eats in notes/appointment body.
I ended up with the following code:
Regex NewlineRegex = new Regex("(\r\n)|(\r)|(\n)");
string valueToWrite = NewlineRegex.Replace(
SecurityElement.Escape(fieldValue), "<br/>")
.Replace(" ", " ")
.Replace("'", "'"); // ' is not in HTML.
And even after that you will read back an extra "\r\n" in the end of the body/notes, so I have to .TrimEnd() them after reading.
you should try "\r\n"

How does one store a statement in C# such as the following way
string EmailBody = "Request no.- ('" + objUserModel.ID + "') has been raised for special
vehicle by requester-( '" + RequesterInfo + "'). " +
"ORG_Unit:'"+ objUserModel.OrgUnit + "'" +
"TDC:'"+ objUserModel.TDC + "'" +
"Customer Name:'"+ objUserModel.CustName + "'" +
"Supply Plant:'"+ objUserModel.CustName + "'";
I am trying to show this variable in multilines in the email for that I need to store it in multiline in the string.
I have seen variations of #$"" but it is not working for me.
Take a look at interpolated strings for including your field values.
For the new lines, there are three distinct items to be aware of: the Enivronment.NewLine constant, the \n character literal, and the HTML <br> element. The last is especially important for emails which use an HTML body.
In this case, I suggest a C# mult-line string literal, with an interpolated value for an extra end line you can set or not as needed based on the platform.
So you end up with this:
string br = ""; // set this to "<br>" for HTML emails
string EmailBody =
$#"Request no.- ('{objUserModel.ID}') has been raised for special{br}
vehicle by requester-( '{RequesterInfo}').{br}
{br}
ORG_Unit:'{objUserModel.OrgUnit}'{br}
TDC:'{objUserModel.TDC}'{br}
Customer Name:'{objUserModel.CustName}'{br}
Supply Plant:'{objUserModel.CustName}'";
The original code was having trouble because of the concatenation. Each line of code for the string was broken up at the end like this: " +, to continue again with a new string literal on the next line. In this way, the line breaks in the code were lost in the resulting string.
The code here addresses this issue by putting everything into the same string literal. There is only one set of double quotes defining the entire string, which now includes the line breaks built into the code. The one thing to be aware of with this technique is you want to shift your strings all the way to the left, regardless of any other indentation in the code.
I suggest joining lines with required delimiter, e.g.
// Set "<br/>" if you want HTML delimiter
// Put "\n" to have a new line,
// Use Environment.NewLine to have OS specific delimiter
string delimiter = "<br/>";
string EmailBody = string.Join(delimiter,
$"Request no.- ('{objUserModel.ID}') has been raised for special vehicle by requester-( '{RequesterInfo}'). ",
$"ORG_Unit:'{objUserModel.OrgUnit}'",
$"TDC:'{objUserModel.TDC}'",
$"Customer Name:'{objUserModel.CustName}'",
$"Supply Plant:'{objUserModel.CustName}'"
);
You can create a multiline string using a verbatim string, ie one starting with #. $ is used for string interpolation on both normal and verbatim strings. BUT that doesn't mean they'll appear as you expect in an email body.
Answering your specific question, this will create a multiline string:
string EmailBody = $#"Request no.- ('{objUserModel.ID}') has been raised for special
vehicle by requester-'({RequesterInfo}').
ORG_Unit:'{objUserModel.OrgUnit}'
TDC:'{objUserModel.TDC}'
Customer Name:'{objUserModel.CustName }'
Supply Plant:'{objUserModel.CustName}'";
Printing this produces:
Request no.- ('3') has been raised for special
vehicle by requester-'(123456').
ORG_Unit:'Blah'
TDC:'XYZ'
Customer Name:'Gone'
Supply Plant:'Gone'
All tabs and spaces were included in the string. To avoid this, each line should start without indenting:
string EmailBody = #$"Request no.- ('{objUserModel.ID}') has been raised for special
vehicle by requester-'({RequesterInfo}').
ORG_Unit:'{objUserModel.OrgUnit}'
TDC:'{objUserModel.TDC}'
Customer Name:'{objUserModel.CustName }'
Supply Plant:'{objUserModel.CustName}'";
This produces:
Request no.- ('3') has been raised for special
vehicle by requester-'(123456').
ORG_Unit:'Blah'
TDC:'XYZ'
Customer Name:'Gone'
Supply Plant:'Gone'
The order of the operators isn't significant. #$ behaves the same as $#.
Sending well formatted Emails
That's a different question, whose answer starts with Don't Use .NET's SmtpClient. The documentation page of the class warns :
We don't recommend that you use the SmtpClient class for new development because SmtpClient doesn't support many modern protocols. Use MailKit or other libraries instead. For more information, see SmtpClient shouldn't be used on GitHub.
The code needed to send a message with MailKit is similar to the old SmptClient.
using (var client = new SmtpClient ())
{
await client.ConnectAsync("smtp.gmail.com", 465, SecureSocketOptions.SslOnConnect);
await client.AuthenticateAsync("username", "password");
await client.SendAsync(message);
await client.DisconnectAsync(true);
}
The Create Messages page shows how to create plain text or HTML messages. Some older email clients don't support HTML so it's often necessary to create both a plain text and HTML message.
String interpolation and verbatim strings can be used to create the text for both parts:
string plainBody = #$"Request no.- ('{objUserModel.ID}') has been raised for special
vehicle by requester-'({RequesterInfo}').
ORG_Unit:'{objUserModel.OrgUnit}'
TDC:'{objUserModel.TDC}'
Customer Name:'{objUserModel.CustName }'
Supply Plant:'{objUserModel.CustName}'";
string htmlBody = #$"<div>Request no.- ('{objUserModel.ID}') has been raised for special
vehicle by requester-'({RequesterInfo}').
</div>
<dl>
<dt>ORG_Unit:</dt><dd>'{objUserModel.OrgUnit}'</dd>
<dt>TDC:</dt><dd>'{objUserModel.TDC}'</dd?
<dt>Customer Name:</dt><dd>'{objUserModel.CustName }'</dd?
<dt>Supply Plant:</dt><dd>'{objUserModel.CustName}'</dd>
</dl>";
These can be combined in a single email message with :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Blah Blah", "blah#gmail.com"));
message.Subject = "Special Request";
var builder = new BodyBuilder ();
builder.TextBody = plainBody;
builder.HtmlBody = htmlBody;
message.Body = builder.ToMessageBody ();
Try to use + Environment.NewLine where you need the newline.
+ "vehicle by requester - ('" + RequesterInfo + "'). " + "\n" + "ORG_Unit:'" + objUserModel.OrgUnit + "'" + "\n"
+ "TDC:'" + objUserModel.TDC + "'" + "\n" + "Customer Name:'" + objUserModel.CustName + "'" + "\n"
+ "Supply Plant:'" + objUserModel.CustName + "'";```
If i have understood it correctly you just add ```+ "\n" +```
using string interpolation you can achieve what you want to do here for example:
string EmailBody = $"Request no.- ('\"{objUserModel.ID}\"') has been raised
notice the \ before the "
if you would like to add a new line in the string you can just add
string1 $" this string is writen on one line";
string2 $" this string is \nwriten on two lines";
I have code to display a vehicle by its Make and Model.
productName.Text = p.Make + p.Model
The above code displays the text as such: "BentleyContinental", how can I make the text display as such "Bentley Continental".
You can use string.Format():
productName.Text = string.Format("{0} {1}", p.Make, p.Model);
Or you can use string interpolation (if you are on C# 6 or higher):
productName.Text = $"{p.Make} {p.Model}";
Or you can do just as you have (string concatenation) but add in a space:
productName.Text = p.Make + " " + p.Model;
Use the string.concat method to concatenate string parts.
productName.Text = string.concat(p.Make, " ", p.Model);
In general, you use the string.concat when you know you'll add less than a dozen parts. More than that, or if you are in a loop, there is more benefits using the StringBuilder class.
productName.Text = p.Make + " " + p.Model
Just concatenate a space between two words. I think this is the easiest way.
I need to split string variable by multiple characters, in my case by " ";
Here is my code:
string s_var = "New String variable";
string[] s_mas = s_var.Split(" ");
The Split() method isn't working for me, it says that the argument " " is invalid.
Hoping you guys know how to solve this issue.
You're not specifying the correct arguments.
If you want to split by a string, you need to specify an array.
You also need to specify whether or not to discard empty strings.
Try this:
var s_mas = s_var.Split(new[] { " " }, StringSplitOptions.None);
I don't know what is wrong with the following string:
"Report(" + System.DateTime.Now.ToString("dd-MMM-yyyy") + " to " + System.DateTime.Now.AddMonths(-1).ToString("dd-MMM-yyyy") + ")"
I can't get the concatenated string. I am getting Report(29-Dec-2009. That's all and
the rest gets left out from the string.
What is the reason?
Try this:
string filename =
String.Format(
"Report({0:dd-MMM-yyyy} to {1:dd-MMM-yyyy})",
System.DateTime.Now, System.DateTime.Now.AddMonths(-1));
EDIT: Since in your download box you got your filename broken in first whitespace, you could to try ONE of these:
filename = HttpUtility.UrlEncode(filename); // OR
filename = """" + filename + """";
Seems some browsers doesn't handles whitespaces very nicely: Filenames with spaces are truncated upon download. Please check it you can to download other filenames with whitespace in other sites.
You need to assign it to something:
string s = "Report(" + System.DateTime.Now.ToString("dd-MMM-yyyy") + " to " + System.DateTime.Now.AddMonths(-1).ToString("dd-MMM-yyyy") + ")"
Update: I just saw your update to the question. How are you displaying the string? I'm guessing that you are displaying it in a GUI and the label is too short to display the complete text.
Try this:
string newstring =
string.Format(
"Report ({0} to {1})",
System.DateTime.Now.ToString("dd-MMM-yyyy"),
System.DateTime.Now.AddMonths(-1).ToString("dd-MMM-yyyy")
);
What are you assigning the result to? It would be easier to read the code if you used string.Format
You are not assigning the concatenated result to anything, so can't use it:
string myConcatenated = "Report(" + System.DateTime.Now.ToString("dd-MMM-yyyy") + ")";
Using this code...
string test = "Report(" + System.DateTime.Now.ToString("dd-MMM-yyyy") + " to " +
System.DateTime.Now.AddMonths(-1).ToString("dd-MMM-yyyy") + ")";
I saw the following result.
Report(29-Dec-2009 to 29-Nov-2009)
It could be that the string is being truncated later on. Make sure that you set a breakpoint right after this code is run and check the value of the variable to which it is assigned (test in my case).
If, as in your previous question, you are using this value to create a file, it may be that it's the space before "to" that is causing the problem. Try to use:
"Report("
+ System.DateTime.Now.ToString("dd-MMM-yyyy")
+ "To"
+ System.DateTime.Now.AddMonths(-1).ToString("dd-MMM-yyyy")
+ ")"
instead and see if that fixes it.
If that does fix it, you'll probably need to either figure out how to quote the entire file name so it's not treated as the three separate arguments, "Report(29-Dec-2009", "to" and "29-Nov-2009)". Or simply leave your reports names without spaces.
I'd choose the latter but then I'm fundamentally opposed to spaces in filenames - they make simple scripts so much harder to write :-)
I have a string which would be delivered to my application in the format below:
ece4241692a1c7434da51fc1399ea2fa155d4fc983084ea59d1455afc79fafed
What I need to do is format it for my database so it reads as follows:
<ece42416 92a1c743 4da51fc1 399ea2fa 155d4fc9 83084ea5 9d1455af c79fafed>
I assume the easiest way to do this would be using regular expressions, but I have never used them before, and this is the first time I have ever needed to, and to be honest, I simply don't have the time to read up on them at the moment, so if anyone could help me with this I would be eternally grateful.
What about:
string input ="ece4241692a1c7434da51fc1399ea2fa155d4fc983084ea59d1455afc79fafed";
string target = "<" + Regex.Replace(input, "(.{8})", "$1 ").Trim() + ">";
Or
string another = "<" + String.Join(" ", Regex.Split(input, "(.{8})")) + ">";
You might just be better served having a small static string parsing method to handle it. A regular expression might get it done, but unless you're doing a bunch in a batch you won't save enough in system resources for it to be worth the maintenance of a RegEx (if you're not already familiar with them I mean). Something like:
private string parseIt(string str)
{
if(str.Length % 8 != 0) throw new Exception("Bad string length");
StringBuilder retVal = new StringBuilder(str)
for (int i = str.Length - 1; i >=0; i=i-8)
{
retVal.Insert(i, " ");
}
return "<" + retVal.ToString() + ">";
}
Try
Regex.Replace(YOURTEXT, "(.{8})", "$1 ");
