String to double
I know i ask this in a lot of different areas but its only because I have no idea how to do it. How do I change a string into a double. I tried the following to change a string into an int but it does not work.
[PHP] string myStr = "123" displayBox.text = Convert.ToInt32(myStr);[/PHP] The error that i get is this Cannot implicity convert 'int' to 'string'

Convert.ToDouble()
The reason you got an error is because displayBox.text is a String, and you are assigning an int to a string. Your conversion worked fine. |

Cannot implicity convert 'int' to 'string' The thing is that you're probably trying to put that into a textBox. So the ToInt32 worked fine , but you have to use : ToString() on it like so : displayBox.text = Convert.ToInt32(myStr).ToString(); What exactly are you trying to do ?

string x = "123"; double y = Convert.ToDouble(x); txtResult.Text = Convert.ToString(y);

crawforddavid2006, don't take this the wrong way man, but you really need to learn how to do a bit of research. This could have been found on Google with about 10 mins of searching. Maybe pick up a C# book if you have a good amount of interest in it.

After all those replies i guess that crawforddavid2006 solved the problem, but I am posting another way to do it (one-line way of the snippet submitted by Infinite Recursion):
string str = "123"; textBox1.Text = Convert.ToString(Convert.ToDouble(str)); |
