musefan has given you the perfect answer. Just be aware that if the number can't be converted to an int you will get zero.

I have an extension method that I use when working with text/xml etc files to simplify stuff.

public static class ExtensionMethods<br />{<br />    /// <summary><br />    /// Converts a string to an integer.<br />    /// </summary><br />    /// <param name="value">The string to convert.</param><br />    /// <returns>The integer value of the string if valid; otherwise, zero.</returns><br />    public static Int32 ToInt32(this string value)<br />    {<br />        int result;<br />        Int32.TryParse(value, out result);<br />        return result;<br />    }<br />}

Now I can can just use something like

int intFromFile = stringFromFile.ToInt32();

Solution 1

int result;

int.TryParse("10000", out result);
