Hello,
What should I do if I want to show two values in one message box?
I mean something like:

MessageBox.Show("Your name and age will be: " + name +age ,"New guy");

But this will only split two strings together so it's useless.

This is still one value, which is fine. String concatenation is pretty bad. Use string.Format.

concatenating strings (using +) is generally considered bad practice.

use string.Format(). This allows you to provide any number of 'bits' to insert into a string and allows you to specify where, and what formatting to use

in your above example you would need:

C#

MessageBox.Show(string.Format("Your name and age will be: {0}{1}",name,age) ,"New guy");

Solution 2

Use this...

C#

MessageBox.Show("Your name and age will be: " + name +" "+ age ,"New guy");

OR
Use String.Formate function like this...

C#

MessageBox.Show(string.Format("Your name and age will be: {0}{1}",name,age) ,"New guy");

I'm not a native English speaker, so I might miss the important point here, but I just don't get what "splitting something together" could mean.

For a quick message box you can do this:

C#

MessageBox.Show(
    "InitialStringLiteral"
        + integerVarialbe.ToString()
        + "IntermediateStringLiteral"
        + anotherVariable.ToString()
        + "EvenMoreStringLiteralStuff",
    "HeadingAfterTheComma"
);

You can even define what buttons and icon will be shown. Just see http://msdn.microsoft.com/en-us/library/system.windows.forms.messagebox.show.aspx[^]

Aside from the message box, if you want to concatenate large amounts of strings, consider using a StringBuilder[^].
