[C# Help] Convert string to int

[Ultra Frosty]

How can I transform a string to an int, then output that int to a textbox again? I made the thread title Convert string to int, because I will use this for int, long, double ... etc.

       private void GetAnswer_Click(object sender, EventArgs e)
        {
            string di = diameter.Text; /* diameter is the input textbox */
            float pi = di;
            answer.Text = pi; /* answer is the answer textbox */
        }

Integer.toInt(string)

i think that will convert it to a int

I cant get that to pull up in Visual C# Express 2005. What namespace is that in? An example would be nice.

[Ultra Frosty]

I found it, it is in the System.Convert namespace.

well thats java, i thought they were close enough to work like that

EDIT:

yes i just found that on msdn too

[C#]

int.Parse(string);

or

System.Convert.ToInt32(string);

the string must be in the correct format otherwise it'll throw an exception

Um I was thinking:

int.ParseInt(string);

Java is Integer.parseInt(String);

Interger being the class and parseInt being the method.
