get info from text box

superjoe30superjoe30 Posts: 174Member
This may sound dumb, it's 'cause I'm new to C#.

I have a text box: txtInput
The user enters a value: 3.1415926535
I have a variable: double value

I need value to equal what the user entered, but I get a "Cannot convert string to double" error when I do this: (double) txtInput.text

Help appreciated. Thanks.

    Use Double.Parse() method.

    value = Double.Parse(txtInput.Text);
