I have a variable that is an array of string s and I want to print its values, but these values and consequently the quantity of them is only defined after the system works.
How can I print in a MessageBox , for example, all values of all positions in only MessageBox instead of making a for and print one by one?
Another option would be as follows
var dataTransacao = new string[] {"01/01/2015", "02/02/2015", "03/03/2015" };
MessageBox.Show(String.Format("Datas de transação: {0}", String.Join(", ", dataTransacao)), MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
You can use string.Join()
In the example below the variable strDados contains all comma-separated array items.
string[] dados = { "um", "dois", "três" };
string strDados = string.Join(", ", dados);
MessageBox.Show(strDados);
The MessageBox will show:
one, two, three
You can make this impression by using the Aggregate . For example:
MessageBox.Show(dataTransacao.Aggregate( (acumulador, posicao) => acumulador + ", " + posicao, "Título"), MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
If you declare dataTransacao like this:
var dataTransacao = new string[] {"01/01/2015", "02/02/2015", "03/03/2015" };
It will exit in MessageBox like this:
01/01/2015, 02/02/2015, 03/03/2015
