How to print each substring of a string ?

Well, we've had solutions for Windows Forms and ASP.NET, here's one for the console:

foreach(string s in str.Split(' ')) Console.WriteLine(s);

String split using Split funciton

write string str = "This is a Text Book".Split(' ');
response.write str
or
string str = "This is a Text Book".Split("\n");
response.write str;

Use string split

public partial class Form1 : Form
{
string[] mystring;
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{

}

private void button1_Click(object sender, EventArgs e)
{
mystring = textBox1.Text.Split(' ');
printPreviewDialog1.Document = printDocument1;
printPreviewDialog1.ShowDialog();

}

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
int count = 20;
foreach (string str in mystring)
{
e.Graphics.DrawString(str, textBox1.Font, Brushes.Black, 20, count);
count = count + 15;
}
}
}
