Question

I created a program to read/write with data from another program. I set a value of 7 (of type memory real) in the program, then when I read the value in visual studio, it gives me a string 7.0000000000000. So I created this conversion snippet which works for data of type int which also gives me a string in VS. I don’t know the difference between these 2 data types but logically if both data types give me a string, I should be able to run this code. Why the memory real data skips the if here?

 if (Regex.IsMatch(value, "^[0-9 ]+$"))
                {
                    ValueBox.Text = Double.Parse(value).ToString();
                }
                else
                {
                    ValueBox.Text = value;
                }

EDIT: I use 2 given dlls, I believe there is a conversion issue in the dll but my code should still work.

EDIT 2: This code is a section from my program, value and other variables are already defined

Answer 1

Skip the Regex and use TryParse

Double.TryParse Method

Int32.TryParse Method

or can just format “N0”

d.ToString(“N0”)
